Posts: 58
I'm stuck with what should be in my pre and post workout snacks.
I heard that there should be a lot of sugar in a post snack? (Is that true)
Because I go to the gym after work, I usually have a muesli bar or a fruit an hour or half before. A lot of the times I forget to take my snack before gym and get worried. Does a muesli bar or an apple fit in to these meals/snacks? I do 40 minutes of cardio and usually 20-25 minutes strength training/cardio.
What would be some snack ideas? And not too complicated as I'm at work and usually pack my lunch the night before.

for the sugar part i suggest to take half a grapefruit pre and post workout - that should be enough sugar and has some more benefits for your workout. If you can manage it somehow - get a fresh one.
Quote: "A study from the Scripps Clinic (San Diego) reported that subjects eating half a grapefruit or drinking 8 ounces of grapefruit juice three times a day while otherwise eating normally lost an average of 4 pounds in 12 weeks, with some test subjects losing more than 10 pounds without dieting. The researchers suggest the effect is likely due to grapefruit’s ability to reduce insulin levels. Try adding half a grapefruit to a few of your meals such as breakfast, lunch and preworkout."
Besides that you could take some (1-3) eggs or tuna fish for protein - eggs have all the neccessary amino acids included. Or combine both in a salad - of course self made and without these calory bomb dressings. create your own yoghurt or olive oil (e.g. my fav. is olive oil with mustard and balsamico + some fresh herbs) dressing.
no matter if you want to lose weight or gain muscels (or both) - protein rich fresh food is the way to go. in first case - (losing weight) remove muesli bars from your meals list ;-)
ps: i'm doing workout 5-6 days a week, alternating between a) strength training with 30mins normal cardio (running) and every 2nd day 50-60 mins hiit cardio training with only ~15mins strength training. i try to eat not so much calories, good fats (fish,olive oil, nuts), a lot protein (chicken,turkey, low fat curd cheese, eggs, tuna, etc.) and good carbs (potatoes, natural brown rice, wholemeal noodles..).0 -
This website has excellent info on pre/post workout meals...

It's the one i've used for my program and is working well
Hope it helps!0 -
My pre workout meals are foods rich in carbs or vitamin c
and my post workout meals are foods rich in protein & calcium or drink protein shake0 -
I heard a glass of chocolate milk is good for a post workout snack
i like tru moo.0 -
Thanks everyone! I get it now!
Pres and posts should be packed with protein and carbs!!

To be fair, there's no real need for specific pre and post workout meals. As long as you get your required macros for the day, you're fine.
In short, eat whatever helps you perform better at the gym. Some people need big meals right before working out, others do better completely fasted. Some people love having big post workout meals after a gym session, others can't eat at all. Look at overall totals, and don't worry about trying to micromanage every gram, because it doesn't matter.0 -
I've just joined MFP. I exercise in the morning and in the early evening. Can anyone tell me how long i should wait after eating before i start my exercise regime. Thanks0

"50 Rules Of Fat-Burning: The Strongest Clinical Research From Around The World
Whatever your doing must not be working. Why else would you be reading this?
You swapped fried chicken for grilled and your treadmill is finally getting more attention than your TiVo. But your body isn’t quite where you want it to be. Don’t worry: Your bag of fat-burning tricks isn’t empty yet. We’ve collected 50 comprehensive tips, all backed by more science than a NASA shuttle launch. By the time you’ve incorporated these fat-burning gems, we’ll have 50 more for you. But by then, you probably won’t need them.
What You Eat
Getting lean obviously relies heavily on a solid nutrition plan. So it should come as no surprise that what and how you eat can have a big impact on your success. Use these 11 food rules to amp up your fat-burning potential.
1. Go Pro
A high-protein diet not only promotes hypertrophy but also enhances fat loss. Researchers at Skidmore College (Saratoga Springs, New York) found that when subjects followed a high-protein diet–40% of total daily calories from protein–for eight weeks, they lost significantly more bodyfat, particularly abdominal fat, than those following a low-fat/high-carb diet. One reason eating more protein may work is that it boosts levels of peptide YY, a hormone produced by gut cells that travels to the brain to decrease hunger and increase satiety.
2. Slow Down
When you reach for carbs, choose slow-digesting whole grains such as brown rice, oatmeal and whole-wheat bread, which keep insulin levels low and steady, and prevent insulin spikes from halting fat-burning and ramping up fat-storing.
A study conducted by researchers at Pennsylvania State University (University Park) found that subjects following a low-calorie diet with carbs coming only from whole grains lost significantly more abdominal fat than those following a low-calorie diet with carbs from refined sources.
3. Get Fat
Not only will certain fats–particularly omega-3s –not lead to fat gain, but they can actually promote fat loss. Eating fat to lose fat seems counterintuitive, but if you keep your fat intake at about 30% of your total daily calories by choosing fatty fish such as salmon, sardines or trout as well as other healthy fat sources such as olive oil, peanut butter and walnuts, you can actually boost your fat loss compared to eating a low-fat diet.
4. Egg You On
Eggs are packed with protein and have been shown to promote muscle strength and mass, and research shows that subjects consuming eggs for breakfast not only eat fewer calories throughout the day but also lose significantly more bodyfat. We recommend eating eggs for breakfast daily, scrambling three whole eggs with three egg whites.
5. Unforbidden Fruit
A study from the Scripps Clinic (San Diego) reported that subjects eating half a grapefruit or drinking 8 ounces of grapefruit juice three times a day while otherwise eating normally lost an average of 4 pounds in 12 weeks, with some test subjects losing more than 10 pounds without dieting. The researchers suggest the effect is likely due to grapefruit’s ability to reduce insulin levels. Try adding half a grapefruit to a few of your meals such as breakfast, lunch and preworkout.
6. Milk It
Dairy products are rich in calcium, which can help spur fat loss, particularly around your abs. This may be due to the fact that calcium regulates the hormone calcitriol, which causes the body to produce fat and inhibit fat-burning. When calcium levels are adequate, calcitriol and fat production are suppressed while fat-burning is enhanced. Adding low-fat versions of cottage cheese, milk and yogurt (Greek or plain) to your diet are great ways to boost protein intake and aid fat loss.
7. An Apple A Day
Apples are a great slow-digesting carb that contain numerous beneficial antioxidants. One group of compounds known as apple polyphenols has been found to boost muscle strength, endurance and even fat loss, especially from around the abs. While apple polyphenols appear to directly decrease bodyfat by increasing the activity of genes that enhance fat-burning and decrease fat production and storage, the boost in endurance and strength can help further fat loss by allowing you to train harder longer.
A typical large apple provides about 200 mg of apple polyphenols and about 30 grams of carbs.
8. Spice It Up
Hot peppers contain the active ingredient capsaicin, a chemical that has been shown to promote calorie-burning at rest as well as reduce hunger and food intake. Its effects are particularly enhanced when used with caffeine, and research also shows that it boosts fat-burning during exercise. Try adding crushed red pepper, hot peppers or hot pepper sauce to your meals to burn extra calories and fat. If you can’t stand the heat, try supplements that contain capsaicin.
9. Go Nuts
A study from Loma Linda University (California) reported that subjects following a low-calorie, higher-fat diet (40% of total calories from fat) with the majority of fat coming from almonds lost significantly more bodyfat and fat around the abs in 24 weeks than subjects consuming the same calories but more carbs and less fat. So be sure to include nuts such as almonds, Brazil nuts, macadamia nuts and walnuts in your diet.
10. Be Multi-Organic
Sure, it’s pricier, but organic beef and dairy are worth the extra bucks. UK scientists found that organic milk had about 70% more omega-3 fatty acids than conventional milk, and a study published in the Journal of Dairy Science found that grass-fed cows produced milk containing 500% more conjugated linoleic acid [CLA) than cows who ate grain. Meat from organically raised cattle also contains higher levels of CLA and omega-3 fats. Since omega-3s and CLA can help you drop fat as well as gain muscle, it makes sense to shell out the extra cash for organic cheese, cottage cheese, milk and yogurt as well as grass-fed beef.
11. Add Some GUAC
Avocados are full of monounsaturated fat, which isn’t generally stored as bodyfat. They also contain mannoheptulose, a sugar that actually blunts insulin release and enhances calcium absorption.
As mentioned earlier, keeping insulin low at most times of day is critical for encouraging fat loss, and getting adequate calcium can also promote fat loss. Try adding a quarter of an avocado to salads and sandwiches.
What You Drink
Beverages can play an important role in your ability to drop fat. Consider sipping or passing on these eight beverages to get extra-lean.
12. Go Green
The main ingredient in green tea, epigallocatechin gallate (EGCG), inhibits the enzyme that normally breaks down the neurohormone norepinephrine. Norepinephrine keeps the metabolic rate up, so preventing its breakdown helps you burn more calories throughout the day. Drinking green tea is a great way to stay hydrated during workouts, as a new study in The Journal of Nutrition reported that subjects drinking green tea and exercising lost significantly more abdominal fat than those drinking a placebo.
13. In The Black
Green, oolong and black teas all come from the same plant, but different processing causes black and oolong teas to lose their green color and turn brownish/black. Oolong tea has been shown to enhance metabolic rate due to polyphenols other than EGCG. Black tea may also aid fat loss: Researchers from University College London reported that black tea consumption can help reduce Cortisol levels, which encourages fat storage especially around the midsection.
14. Be Aqua Man
German researchers have shown that drinking about 2 cups of cold water can temporarily boost metabolic rate by roughly 30%. The effect appears to be mainly due to an increase in norepinephrine.
15. Get Energized
Certain energy drinks have been shown to boost fat loss. University of Oklahoma (Norman) researchers reported in a 2008 study that when 60 male and female subjects consumed a diet energy drink containing 200 mg of caffeine and 250 mg of EGCG from green tea extract for 28 days, they lost more than 1 pound of bodyfat without changing their diets or exercise habits.
16. Whey Lean
Drinking whey protein as a between-meals snack is a smart way to enhance not only muscle growth but also fat loss. UK researchers found that when subjects consumed a whey protein shake 90 minutes before eating a buffet-style meal, they ate significantly less food than when they consumed a casein shake beforehand. The scientists reported that this was due to whey’s ability to boost levels of the hunger-blunting hormones cholecystokinin and glucagonlike peptide-I.
17. Say Soy-Anara To Fat
Soy protein is a proven fat-burner. In fact, in a 2008 review paper University of Alabama at Birmingham researchers concluded that soy protein can aid fat loss, possibly by decreasing appetite and calorie intake. The scientists also found that subjects drinking 20 grams of soy daily for three months lost a significant amount of abdominal fat.
18. Get Thick
When you whip up a protein shake, consider making it thicker by using less water. It could help you feel less hungry while dieting. In a study from Purdue University (West Lafayette, Indiana), subjects drank two shakes that were identical in nutritional content, and reported significantly greater and more prolonged reductions in hunger after drinking the thicker shake.
19. Not So Sweet
Even though artificially sweetened drinks are calorie-free, drinking too many can actually hinder your fat-loss progress. It seems that beverages like diet soda mess with your brain’s ability to regulate calorie intake, causing you to feel hungrier than normal so you eat more total calories.
Other research suggests that the sweet taste of these drinks can increase the release of insulin, which can blunt fat-burning and enhance fat storage.
What Supplements You Take
While whole foods are the key element to getting lean, supplements can provide a potent fat-burning stimulus. Consider using these six supps.
20. Go Even Greener
The majority of studies showing the effectiveness of green tea for fat loss have used green tea extract. One study confirmed that the EGCG from the extract was absorbed significantly better than the EGCG from the tea. Take about 500 mg of green tea extract in the morning and afternoon before meals.
21. See CLA
You’ll also want to add the healthy fat CLA to your supplement regimen. CLA can significantly aid fat loss while simultaneously enhancing hypertrophy and strength gains. Research shows it can even help specifically target ab fat.
22. Go Fish
As mentioned in tip No. 3, the essential omega-3 fats in fish oil promote fat loss, which is enhanced with exercise. This is also true for fish-oil supplements containing omega-3 fats. Take 1-2 grams of fish oil at breakfast, lunch and dinner.
23. You Bet Your Astaxanthin
Japanese researchers reported in a 2008 study that mice supplemented with astaxanthin combined with an exercise program for four weeks saw accelerated fat-burning, greater fat loss and enhanced endurance compared to mice that just exercised. The scientists determined that astaxanthin protects the system that transports fat into the mitochondria of muscle cells where it’s burned as fuel. Take 4 mg of astaxanthin with food once or twice per day, with one dose taken with your preworkout meal.
24. Go Commercial
A 2009 study reported that lifters taking the fat-burner Meltdown by VPX (containing caffeine, synephrine, yohimbine and beta-phenylethyl-amine, to name a few) burned 30% more calories and had a more than 40% increase in markers of lipolysis (fat release from fat cells) for the 90 minutes afterward when researchers measured calorie burn compared to when subjects consumed a placebo. Regardless of the brand of thermogenic you choose, follow label instructions and take the other five supplements mentioned here as well.
How You Lift
The way you weight-train can have a huge effect on how much fat you burn. Consider these eight rules when hitting the iron.
25. Carry More Fat Away With Carnitine
This amino-acidlike compound is critical for carrying fat in the body to the mitochondria of cells, where it’s burned away for good. Research confirms that taking carnitine when dieting can help maximize fat-burning efforts. Take 1-2 grams of carnitine in the form of L-carnitine, L-carnitine L-tartrate or glycine propionyl-L-carnitine.
26. Go Heavy
Excess post-exercise oxygen consumption refers to the increased metabolic rate you enjoy after a workout. Scien- tists at the Norwegian University of Sport and Physical Education (Oslo) analyzed multiple studies and found that training with heavier weights for fewer reps produces a greater rise in resting metabolic rate that’ll last longer compared to training with lighter weights and doing more reps. Although most guys may think they need to train with higher reps to burn more fat, you still want to lift heavy (3-7 reps) some of the time to maximize the calories and fat you burn when you’re not at the gym.
27. Go Light
While lifting heavy does burn more calories post- workout, performing higher reps burns more calories during the workout, as College of New Jersey (Ewing) researchers reported at a 2007 annual meeting of the National Strength and Conditioning Association.(51) Be sure to mix up your training by using lighter weight and higher reps (10-20) during some workouts and heavy weight and low reps (3-7) in others. Another way to get the best of both worlds is to perform four sets of most exercises, doing your first two sets with heavy weight and low reps and the last two with light weight and high reps.
28. Rest Less
Researchers from the College of New Jersey (Ewing) also discovered that when subjects rested 30 seconds between sets on the bench press, they burned just more than 50% more calories than when they rested three minutes.
To maximize fat toss, keep your workout moving by resting less than a minute between sets.
29. Force It
A study on collegiate football players found that using a high-intensity weight program–just one set per exercise for 6-10 reps to failure, plus forced reps and a static contraction for several seconds–caused more bodyfat loss in 10 weeks than a lower-intensity program consisting of three sets of 6-10 reps per exercise taken just to muscle failure. This could be due to a greater hike in growth hormone (GH) in the high-intensity group: In a study from Finland, forced reps boosted GH three times higher than training to failure. Go past failure when trying to get lean by using forced reps, static contractions, rest-pause or drop sets.
30. Be Free
Using free weights, especially in multijoint moves such as the squat, has been found to burn more calories than doing similar exercises on machines like the leg press. Scientists said the difference may be due to the greater number of stabilizer muscles used during multijoint exercises done with free weights.
31. Feel The Need For Speed
Fast, explosive reps burn more calories than the typical slow, controlled reps you’re used to doing in the gym, say researchers from Ball State University (Muncie, Indiana). They believe that because fast-twitch muscle fibers are less energy-efficient than their slow-twitch counterparts, they burn more fuel during exercise. To perform fast reps in your workouts, choose a weight equal to 30`% of your one-rep max (or a weight you can lift for 15-35 reps) for each exercise. Do your first two sets with 3-8 fast reps, then follow with 2-3 sets of normal-paced reps.
32. Be Negative
In one recent study, subjects who performed a negative-rep workout of three sets of the bench press and squat increased their GH levels by almost 4,000%. Since GH frees up fat from fat cells, using negative reps may help you shed extra bodyfat. To add negatives to your routine, either have a spotter help you get 3-5 negative reps after reaching failure on a regular set, or load the bar with about 120% of your one-rep max and have a spotter help you perform five negative reps that take you 3-5 seconds each to complete.
33. Tune In
Listening to your iPod can boost your workout intensity and fat-loss efforts. A study conducted by the Weider Research Group and presented at the 2008 annual meeting of the National Strength and Conditioning Association found that trained subjects listening to their own music selection could complete significantly more reps than when they trained without their preferred music.
How You Run
Cardio, obviously, is a primary component of getting lean. It’s the easiest way to burn the most calories during exercise. Use these eight rules to help you maximize your fat loss.
34. Go After It
Do your cardio after you hit the weights. Japanese researchers found that when subjects performed cardio after resistance training, they burned significantly more fat than when they did cardio first. The scientists also reported that fat-burning was maximal during the first 15 minutes of cardio following the weight workout, so hit the stationary bike, elliptical machine or treadmill after you lift, even if it’s for just 15 minutes.
35. Hiit It
The best way to burn the most fat with cardio is via high-intensity interval training (HIIT). This involves doing intervals of high-intensity exercise (such as running at 90% of your max heart rate) followed by intervals of low-intensity exercise (walking at a moderate pace) or rest. A litany of research confirms that this burns more fat than the continuous, steady-state cardio most people do at a moderate intensity, such as walking for 30 minutes at 60%-70% of their max heart rates.
36. Stagger It
In one study, subjects who did three 10-minute bouts of running separated by 20-minute rest periods found the workout easier than when they ran at the same intensity for 30 minutes. The intermittent cardio even burned more fat, and has also been shown to burn more calories postworkout than the same amount of continuous exercise.
37. Fashionably Late
The time of day you do your cardio can impact how many calories you burn post-workout. University of Wisconsin, La Crosse, researchers reported that endurance-trained subjects who performed 30 minutes of stationary cycling between 5 p.m. and 7 p.m. raised their metabolic rates higher postworkout than when they did the same cardio exercise between 5 a.m. and 7 a.m. or between 11 a.m. and 1 p.m. While your best bet is to train whenever it best fits your schedule, try training in the evening to enhance your postworkout calorie burn.
38. Be Scottish
University of Edinburgh (Scotland) researchers reported that when subjects did 4-6 30-second sprints on a stationary cycle separated by four minutes of rest for just two weeks, their blood-glucose and insulin levels were reduced by almost 15% and 40%, respectively, and insulin sensitivity improved by about 25%, following consumption of 75 grams of glucose. Keeping insulin levels low and steady can help maximize fat-burning and minimize fat storage.
So even if you don’t have 20-30 minutes for a cardio workout, doing just 2-3 minutes of sprinting can at least help keep insulin down and fat-burning up.
39. Climb It
Consider other forms of cardio. A recent study from Italy found that when subjects rock-climbed, their average heart rates were about 80% of their max, which equates to a pretty intense cardio session. In addition, subjects burned about 12 calories per minute for a 180-pound guy, or just less than 400 calories in 30 minutes. Check out indoor or outdoor rock-climbing sites in your area.
40. Kick It
Another way to get your cardio is with martial arts. Wayne State College (Nebraska) researchers found that when beginning martial artists performed a tae kwon do workout of cycling between front kicks, butterfly stretches, forearm strikes, crunches, side kicks, quad stretches and push-ups, their heart rates rose 80% and they burned about 300 calories per half-hour. Besides tae kwon do, you can try aikido, jiu-jitsu, judo, karate, kung fu or any other style of martial arts.
41. Spit It Out
University of Birmingham (Edgbaston, UK) scientists found that when trained cyclists rode as fast as possible while rinsing their mouths with a beverage similar to a sports drink and spitting it out every 7-8 minutes, they could cover a certain mileage three minutes faster than when they rinsed with water. We don’t suggest you try this in an indoor cycling class, but rinsing your mouth every 10 minutes with a sports drink and spitting it out could help you train at a higher intensity–without the added calories.
Other Rules
Some things that can impact your ability to lose fat may not be directly related to what you eat or drink, or to your exercise routine. Still, these nine tips could aid fat loss.
42. Get Up
Research from Australia found that out of 2,000-plus subjects who exercised vigorously for at least 2.5 hours per week, those who watched more than 40 minutes of television per day had higher waist circumferences than those watching less than 40 minutes. The scientists theorize that sitting for prolonged periods compromises the body’s ability to burn fat, which was shown by University of Missouri-Columbia researchers in both animals and humans. Avoid this slump by getting up and stretching at least every 20 minutes while sitting at work or at home.
43. Take A Picture
A picture could be worth a thousand calo- ries. Researchers from the University of Wisconsin-Madison found that test subjects who recorded with photographs what they ate for one week reported that the images triggered critical evaluation of the food before eating it, prompting them to make better food choices. This wasn’t the case for subjects who simply wrote down what they ate. Try keeping a photo food log as well as a journal in which you calculate your macronutrient intake.
44. Portion It
One study from Cornell University (Ithaca, New York) reported that when moviegoers were given a large acontainer (about 22 cups)of fresh popcorn during a movie, they ate 45% more than those given a medium container (about II cups). Even more disturbing was that subjects given a large container of stale popcorn still ate about 35% more than those given a medium container, even though they rated the popcorn’s taste as bad.
You can use this research in a couple of ways: For lean protein sources, give yourself a large amount; for side dishes such as rice, potatoes and bread, keep the serving on the small side.
45. Laugh It Off
Japanese scientists found that when subjects ate a 500-calorie meal while watching a 40-minute comedy show, their blood-glucose levels were much lower than when they consumed the same meal during a boring 40-minute lecture. The researchers suggest that laughter may have altered subjects’ brain chemistry in such a way that glucose entered the blood more slowly, or blood glucose was taken up by the muscles more rapidly. Try eating meals while watching something funny on TV to keep your blood-glucose and insulin levels low to help encourage fat loss.
46. Sleep On It
One study in the American Journal of Epidemiology reported that subjects sleeping five hours or less per night were one-third more likely to gain 30-plus pounds over the 16-year study than those who slept seven hours or longer per night. This may be due to an imbalance in the hormones leptin and ghrelin: While leptin decreases hunger and increases the metabolic rate, ghrelin boosts hunger. A study by University of Chicago researchers found that men who were sleep-deprived for two days experienced a rise in ghrelin levels and a drop in leptin levels, along with a concomitant rise in hunger. A Stanford University (California) study showed that subjects who slept the least had lower levels of leptin and higher levels of ghrelin and bodyfat compared to those who slept eight hours.
Try to get 7-9 hours of sleep every night to not only enhance your recovery but also aid your health and help you keep fat off.
47. Chew It
A study done at Glasgow Caledonian University (Scotland) found that subjects who chewed gum between meals ate significantly less food at the second meal than those who didn’t chew gum. The researchers concluded that chewing gum increases satiety and therefore reduces food intake.
48. Be A Transporter
Remember, any activity you do burns calories, and burning more calories than you consume is the most critical aspect of getting lean. So consider how far away certain destinations are such as work, the gym, the grocery store and your friends’ homes. Depending on the distance and the time you have, walk or bike to burn more calories and fat.
49. Feel The Vibe
In a study from Stony Brook University (New York), mice placed on a vibrating platform for 15 minutes a day for up to 15 weeks were found to have less bodyfat than mice not exposed to vibration. Research in humans has seen similar results with vibration exposure enhancing fat loss. If your gym has a vibration machine–often called a Power Plate–get a trainer to walk you through it and consider using it for a few minutes a couple of times per week.
50. Be A Gamer
The popular and very active video game Dance Dance Revolution can provide a great workout, according to researchers from the University of Wisconsin, La Crosse.
They reported that adult subjects burned as many as 10 calories per minute playing the game, which is equivalent to a good run.

"A Scientific Approach To Pre/Post Exercise Nutrition To Maximize The Training Effect
When implemented properly and consistently, strategic pre- and post-workout supplementation can greatly increase the effectiveness of your training. Without optimum nutritional strategies, the body’s response to training can only be considered a compromise at best.
From this perspective, training and diet cannot be considered as separate factors. The food and supplements that you take, and the work that you faithfully perform in the gym, are both part of your training. On the day of competition it will not be the athlete who trained harder who wins, it will be the athlete who trained smarter.
Introduction
Exercise causes acute changes in the metabolic environment of muscle tissue. First there is a significant increase in blood flow to working muscles. There is also a sharp increase in catecholamines (e.g. noradrenalin, adrenalin). These changes favor catabolism during exercise, and anabolism immediately after exercise. Because these changes are acute, some lasting only a few hours, the pre and post exercise meals are critical to optimizing the anabolic effect of exercise. This article will discuss pre- and post-exercise nutritional strategies based on current research in this area.
Before
Pre-workout nutritional strategies are based on providing alternative energy substrates (mainly carbohydrate) to preserve energy stores, and taking advantage of increased blood flow to muscle tissue.
Carbohydrates
High intensity exercise places great demand on glycogen stores. Glycogen is the sugar stored in the liver and muscles. Because high intensity exercise burns energy at such a high rate, the body is unable to supply sufficient oxygen to be able to use fat for fuel. Instead, it must use sugar both stored in the muscle and brought in from the blood.
Consuming simple sugars right before training can reduce the amount of glycogen used during exercise. This can prolong performance. More importantly, higher blood sugar and insulin levels appear to create a hormonal milieu favorable to anabolism (growth).
During exercise, cortisol accelerates lipolysis, ketogenesis, and proteolysis (protein breakdown). This happens in order to provide additional fuel substrates for continued exercise. The effects of cortisol may also be necessary to provide an amino acid pool from which the muscle can rebuild new contractile proteins if there are insufficient amino acids delivered from the blood. This ensures that some degree of adaptation can occur regardless of the availability of dietary protein. Over time however, if this process is not balanced with additional dietary protein, the net effect will be only maintenance or even a decrease in functional muscle tissue, as is evident during periods of starvation or prolonged dieting. Fortunately, there is only a non-significant rise in cortisol levels when carbohydrates were consumed during exercise. (Tarpenning, 1998) The net effect is a more rapid increase in the cross sectional area of the muscle fibers with the greatest effect seen in type-II fibers.
This may be a less expensive option for those who were thinking of using phosphatidylserine. In this case, carbohydrate administration appears to down regulate the hypothalamic-pituitary-adrenal axis, probably through insulin or perhaps through the presence of carbohydrate itself. This would, in effect, greatly reduce the body’s catabolic response to exercise stress. All good news for bodybuilders.
Protein
Another pre-workout strategy involves taking advantage of increased blood flow to working muscles. Because the availability of amino acids is often the limiting factor for protein synthesis, a pre-workout protein meal will enhance the delivery of amino acids to muscle tissue. Research has demonstrated the effectiveness of a pre-workout protein drink.
Amino Acids
Delivery of amino acids has been shown to be significantly greater during the exercise bout when consumed pre-workout than after exercise (Tipton, 2001). There is also a significant difference in amino acid delivery in the 1st hour after exercise, with the pre-exercise protein drink providing a significant advantage. Net amino acid uptake across the muscle is twice as high with a pre-workout protein drink as compared to consuming it after. Phenylalanine disappearance rate, an indicator of muscle protein synthesis from blood amino acids, was significantly higher when amino acids were taken pre-workout.
These results indicate that the response of net muscle protein synthesis to consumption of a protein solution immediately before resistance exercise is greater than that when the solution is consumed after exercise, primarily because of an increase in muscle protein synthesis as a result of increased delivery of amino acids to the leg.
After
During exercise muscles use metabolic fuels at an accelerated rate. In order for physical work to be continuous, the body mobilizes stored fuels to make fatty acids, glucose, and amino acids available for oxidation. This is a catabolic process and cannot occur simultaneous to anabolic processes such as glycogen formation and protein synthesis.
In order for the body to recover from exercise, the catabolic environment must be quickly changed to an anabolic environment. The food that you eat after training affects the hormonal milieu in your body in order for this to take place. With the rapid introduction of carbohydrate, protein, and fat into the system post exercise, the body is able to begin reparations on damaged tissue and replenish fuel reserves.
Carbohydrates
Carbohydrates are important for performance and perhaps more importantly for glycogen recovery. Studies have shown an increased ability of muscle tissue to take up serum glucose immediately following strenuous exercise (Goodyear 1998). This is due to what is called, “non-insulin dependant glucose uptake”. After a meal, muscle cells transport glucose across the cell membrane in response to the hormone insulin. Insulin binds with its receptors at the cell surface causing a cascade of events that ends with proteins, called glucose transporters, being translocated to the cell surface. Once at the cell surface, these glucose transporters allow glucose to pass through the membrane where they can be phosphorylated and eventually stored as glycogen. Membrane transport of glucose will exhibit saturation kinetics similar to the effect of increasing substrate concentration on the activity of enzymes. The number of glucose transporters limits the rate of glucose entry into your muscle cells. Once all available glucose transporters are associated with a glucose molecule, the rate of glucose entry will go no higher.
There are at least 5 different classes of glucose transporter proteins. They are designated GLUT1, GLUT2, GLUT3, GLUT4, and GLUT5. Each class of GLUT protein differs in its kinetic parameters and is found in specific tissues. GLUT-4 is the primary isoform regulated by insulin, and sensitive to muscle contraction.
Muscle contractions, much like insulin, cause a separate set of GLUT-4 proteins to be temporarily translocated to the surface of the muscle cell (Sherman 1996). This greatly increases the rate at which muscle tissue can take in glucose from the blood after a bout of exercise. The effects of exercise on glucose uptake last for a few hours into the post exercise period. If the post exercise meal is lacking in carbohydrates, the replenishment of glycogen is delayed.
If carbohydrates are lacking in the diet, exercise will cause a glucose deficit and glycogen stores will continue to fall without being replenished to pre exercise levels.
Simple vs. Complex
There has been some controversy about which type of carbohydrate is best for post exercise glycogen replenishment. Some argue that simple sugars such as dextrose are best after exercise. Others say that drinks with glucose polymers are best. Still others say that there is no need to buy fancy sports drinks and that simply eating a meal high in carbohydrates such as pasta or rice is sufficient. Studies have shown no difference between different types of carbohydrates eaten post exercise and the rate of glycogen replenishment as long as sufficient quantities of carbohydrate are consumed (Burke 1997). Even when the post exercise meal contains other macronutrients such as proteins and fats, the rate of glycogen replenishment is not hindered, given there is sufficient carbohydrate in the meal as well. These studies tell us that the rate-limiting step in glycogen replenishment after exercise is not in digestion or the glycemic index of a given source of carbohydrate. Over a 24-hour period it is the total amount of carbohydrate consumed that is important. The rate-limiting step in glucose uptake during exercise is determined by the rate of phosphorylation once glucose has entered the muscle cell (Halseth 1998). Glycogen synthase activity is also a possible rate-limiting step (Halseth 1998).
These processes are not readily influenced by the composition of the “post exercise” meal, but rather by the extent to which glycogen was depleted during exercise as well as the amount of carbohydrate and fat consistently included in the diet.
Recommendation
It is recommended that at least 0.7 – 1.0 gram of carbohydrate per kilogram body weight be consumed immediately after exercise and then again 1-2 hours later. If you experience gastric upset try increasing the amount of water you consume with the carbs. Try to shoot for a total of 7-10 grams of carbohydrate per kilogram of body weight over a 24-hour period 3 for maximum glycogen storage. This may well be in excess of caloric needs but it is important to shoot for this intake if glycogen storage is your primary goal.
Protein
Protein is another critical nutrient post-exercise. Protein is essential to post exercise anabolism. Protein provides amino acids that are used to rebuild damaged tissues as well as provide enzymes and carrier proteins necessary for adaptation to exercise.
Without protein, which supplies essential amino acids for endogenous protein synthesis, the body’s ability to adapt to exercise is greatly diminished.
The Research
Studies have shown a 12 to 14 day period after the onset of an unaccustomed exercise program, in which nitrogen balance, the ratio of protein intake to protein loss, is negative (Butterfield 1987). Any study looking at protein needs and exercise must take this into account. Nitrogen balance during this period appears to be insensitive to total caloric intake, but can be improved with a high protein intake if adequate calories are supplied (Gontzea 1975). Even though additional protein intake will prevent nitrogen balance from becoming negative, it will still fall despite high protein intake during the first two weeks of exercise.
Muscle specific messenger RNA (mRNA) produced subsequent to training has a half-life of only 4-5 hours. It is so short because mRNA has no “quality control” mechanism built into the coding. By keeping the half-life short, any errors in the sequence won’t be able to produce enough defective proteins to do irreparable damage to the cell or organism. This also allows tight control of protein metabolism.
Importance Of Timing
The timing of protein intake is important. If the anabolic stimulus from exercise is to be maximized, a steady flow of amino acids must bathe the muscle while mRNA content is high. It should be no surprise that the optimum time for protein intake after your workout is relatively brief compared to frequency of training a particular muscle. Muscle protein synthetic rate (MPS) is elevated in humans by up to 50% at about 4 hours following a bout of heavy resistance training, and by 109% at 24 hours following training. A study done by Macdougall (MacDougall et al 1995) further examined the time course for elevated muscle protein synthesis by examining its rate at 36 hrs following a bout of heavy resistance training. Six healthy young men performed 12 sets of 6- to 12-RM elbow flexion exercises with one arm while the opposite arm served as a control. MPS was calculated from the in vivo rate of incorporation of L-[1,2-13C2] leucine into biceps brachii of both arms over 11 hours. At an average time of 36 hours post-exercise, MPS in the exercised arm had returned to within 14% of the control arm value, the difference being nonsignificant.
The following conclusions can be drawn from this study, following a bout of heavy resistance training, muscle protein synthetic rate increases rapidly, is more than double at 24 hours, and then declines rapidly so that at 36 hours it has almost returned to baseline.
Recommendations
Current recommendations for total protein intake for athletes is between 1.6-1.8 grams per kilogram body weight, depending on who you read, however, it is not uncommon for bodybuilders to consume in excess of 2 grams per kg of body weight with no ill effects. It should be remembered that the body does not have the capacity to effectively store amino acids. Protein should be eaten at least every 3-4 hours. The evening meal should contain slowly digesting protein that will allow a steady release of amino acids into your system well into the night. Dinner is a perfect time for steak or other meat dishes.
Fat
Little is known about the effects of fat in the “post-exercise” meal. Total fat intake is probably more important for a bodybuilder than just considering the post-workout meal. Essential fatty acids in sufficient quantities have the ability to alter physiology. Fatty acids such as omega-3s’ and omega-6s’, when consumed in differing ratios in a consistent and deliberate manner, can alter the composition of cell membranes which alters the production of prostaglandins in working muscles and thereby can modify everything from glucose transport to protein synthesis (Hayashi 1999). These effects are seen after at least 5 days of consuming of these fats in moderate to high doses. Eating them immediately after training and at no other time will most likely not have any dramatic effect.
Some forms of fat may delay gastric emptying which theoretically could slow the rate at which nutrients become available to tissues. We can only speculate whether this would have any “long term” effect on gains. Most research indicates that glycogen replenishment is delayed but not reduced when gastric emptying is prolonged.
There is some indication that cholesterol may be an important nutrient immediately after high intensity resistance exercise. Total cholesterol has been shown to be significantly lowered for at least 90 hours following a single bout of resistance exercise (Smith 1994). Serum cholesterol may be needed for incorporation into damaged cell membranes after resistance exercise. I’m not implying that you should eat a high cholesterol meal right after training.
Taken together, research is still lacking where the optimal levels and composition of post-exercise fats are concerned.
Fluids
I couldn’t really write an article about pre- and post exercise nutrition without at least mentioning fluid replacement. Hydration is extremely important on the cellular level. Muscle growth is inhibited by dehydration. In bodybuilding we tend not to focus on fluid replacement because, unlike runners or cyclists, most bodybuilders do not become dehydrated after a single workout. The rate at which you become dehydrated from training depends on how much you sweat (Gisolfi 1990). Some people sweat a lot when lifting and others don’t sweat a drop.
A good rule of thumb is to drink 1 ml for every calorie that you need. So, if you eat 3,500 calories a day, try to drink 3 liters. If you exercise in hot or humid climates add 2 cups of water for every pound you lose while exercising.
It’s about synergy
As mentioned earlier, macronutrient intake modulates post-exercise protein synthesis in ways that are just beginning to be understood. Yes, protein is required to supply essential amino acids for protein synthesis, but what is the mechanism by which protein is controlling this process? Also, are carbohydrates and fats needed only for fuel replacement, or do they play an “interactive” role in post exercise protein synthesis? Recent research has shed light on these questions.
Research
Researchers from the Division of Nutritional Sciences at the University of Illinois examined the effect of post exercise meal composition on protein synthesis. To do this, they looked specifically at the activity of specific proteins known to regulate protein synthesis at the translational level. Initiation of translation (the binding of mRNA to the ribosomal pre-initiation complex) requires group 4 eukaryotic initiation factors (eIFs). These initiation factors interact with the mRNA in such a way that makes translation (the construction of new proteins from the mRNA strand) possible. Two eIFs, called eIF4A and eIF4B, act in concert to unwind the mRNA strand. Another one called eIF4E binds to what is called the “cap region” and is important for controlling which mRNA strands are translated and also for stabilization of the mRNA strand.
Finally, eIF4G is a large polypeptide that acts as a scaffold or framework around which all of these initiation factors and the mRNA and ribosome can be kept in place and proper orientation for translation.
The researchers in this study looked at the association of the mRNA cap binding protein eukaryotic initiation factor-4-E (eIF4E) with the translational inhibitor 4E-eukaryotic initiation factor binding protein-1 (4E-BP1) in the acute modulation of skeletal muscle protein synthesis during recovery from exercise. Fasting male rats were run on a treadmill for 2 h at 26 m/min and were fed immediately after exercise with saline, a carbohydrate-only meal, or a nutritionally complete meal using Ensure Powder (54.5% carbohydrate, 14% protein, and 31.5% fat). Exercised animals and non-exercised controls were studied 1 h post-exercise.
Protein Synthesis
Muscle protein synthesis decreased 26% after exercise and was associated with a fourfold increase in the amount of eIF4E present in the inactive eIF4E.4E-BP1 complex and a concomitant 71% decrease in the association of eIF4E with eIF4G. Refeeding the complete meal, but not the carbohydrate meal, increased muscle protein synthesis equal to controls, despite similar plasma concentrations of insulin. Additionally, eIF4E.4E-BP1 association was inversely related and eIF4E.eIF4G association was positively correlated to muscle protein synthesis.
This study demonstrates that recovery of muscle protein synthesis after exercise is related to the availability of eIF4E for 48S ribosomal complex formation, and post-exercise meal composition influences recovery via modulation of translation initiation.
Results
The results of this study tell us a few things:
#1 | Insulin
Insulin (via carbohydrate intake) alone is not enough to prevent 4E-BP1 from sequestering eIF4E. EIF4E must be free to bind to eIF4G in order for protein synthesis (i.e. recovery from training and net muscle growth) to begin. Insulin as well as amino acids must be present at the same time as indicated by the results from the group that were fed a mixed nutrient meal. So although feeding of the carbohydrate meal resulted in elevated blood glucose and elevated insulin levels, carbohydrates alone are not sufficient to allow protein synthesis to begin.
#2 | Cortisol Levels
The only group that experienced a significant drop in cortisol levels was the mixed meal group. The carbohydrate-only group showed that neither blood glucose nor insulin had any effect on reducing cortisol levels. In contrast, the mixed meal group showed cortisol levels even below those in the control group who did no exercise and were also fed the same meal. It would have been nice for the authors of this experiment to explore the effect of the fat content in the “mixed meal”. From the results we saw that cortisol was lower in the mixed meal group. We can only speculate whether this was due to the protein, the fat, or some combination of protein, fat and carbs. Further research in this area should take into consideration all components of the post exercise meal.
One other issue that might be addressed in humans is the time frame during which re-alimentation is critical to “long term” adaptation to exercise.
In Closing…
Pre- and post-exercise nutrition is critical if one wants to maximize the anabolic effects of exercise. The pre-exercise meal should be high in a quickly digestible protein. This will ensure high delivery of amino acids to the muscle tissue. Carbohydrates can also be taken in to minimize glycogen loss and suppress catabolic hormones. Fat should be avoided pre-exercise unless the exercise is for endurance. The post exercise meal should consist of carbohydrate, protein and perhaps a small amount of essential fats, in a form that is easily and quickly digestible. There are many meal replacement products that fit the bill. Just pick the one you like the most. Don’t worry about sugar content because right after a workout, fat storage is not a big issue. A liquid meal is the most practical method of post-exercise feeding although it is probably not essential.
The ratio of macronutrients depends somewhat on the nature of the training session. An emphasis on high glycemic carbs, complete readily digestible proteins such as whey, egg, or high quality casein, and essential fats such as fish or flax oil will meet the criteria for an effective post exercise meal.

I find, like some people do, that I get tired if I eat before workouts.
I find taking pre workout supplements and drinking plenty of water helps a lot.
I focus on my food after the workout for recovery. Each to their own!
I have found this supplement to give me a great advantage when I workout.

Just eat what suits you to perform the best. Some people needs to eat a lot before workout, some don't. It really depends on you. IF you are looking for some snacks, check this website: http://musclebuildingcookbook.net/0

To be fair, there's no real need for specific pre and post workout meals. As long as you get your required macros for the day, you're fine.
In short, eat whatever helps you perform better at the gym. Some people need big meals right before working out, others do better completely fasted. Some people love having big post workout meals after a gym session, others can't eat at all. Look at overall totals, and don't worry about trying to micromanage every gram, because it doesn't matter.

As i mentioned on other post, i have been using this system for a while now. It works pretty well for me. It is 4 formulas including both workout and the nutrition. It customizes the nutrition to everything about you; your age, weight, height, and metabolism. It also customizes the nutrition to your somatotype and your weight training regimen. Specifically allocates your calories and macronutrients throughout the day depending on when or if you’re working out, You will find here information here, http://www.therippedbody.net/0

Small protein filled snack before workout - like a yogurt or a handful of nuts.
Chocolate milk immediately after workout. Scientifically proven to be the very best thing you can ingest after a workout.
Then eat a full meal sometime in the nest few hours. The chocolate milk allows you to go a while before eating in case you need to cook or get home from the gym without losing energy.0 -

AS for timing, again, it's all personal preference. Your body is constantly utilizing food you eat. Food you've eaten a couple hours before working out will be used just fine for repair and recovery after your workout, provided you are eating enough total calories and macros every day.
If you happen to be a world class elite athlete, then you may need to consider nutrient timing, but even then, most don't.0 -
Thanks for the info! I will try the CLA because I'm definitely:flowerforyou: stuck.0
