Low or no carbs before workouts?

WHAT IF I consumed very little to no carbs prior to my workouts? Would it make my body burn fat for energy instead? And hence help 'fat' loss. I'm not trying to go into a ketosis state as I would take in carbs post my workouts. Anyone tried this? Any opinions?

    I find I can't workout as strenuously if I don't have carbs before my workouts.

    Well I thought if I took in too many carbs then my body would only use that for energy and not burn fat

    Be careful. I tried a very low carb diet once, was eating excellently otherwise, and it made me very ill. I was constantly dizzy and vomiting, and I wasn't working out at the time. Some people simply have to have carbs to function.

    I'm not thinking of going low on carbs..maybe get up in the morning have a low carb high protein breakfast then workout. And then later have the usual diet of adequate carbs and other macronutrients

    probably during your workout but when you eat carbs after it would store as fat. If you ate carbs before the workout then you would burn fat the rest of the day, assuming you are in a caloric deficit

    Not 100% how it works but gives you a simplified version of the acutal process. If you eat the same amount of calories per day, you will store the same amount of fat, or lose the same amount of fat (surplus/deficit) regardless when you eat them.

    So either burn carbs during your workout and fat after, or burn fat during and carbs after, 6 of one, half a dozen of the other.

    I sometimes have a cup of coffee and go for a walk before breakfast but I can not match the speed or endurance I have if I ate breakfast (with carbs) and was able to wait an hour to walk. I burn more calories if I can exercise longer and stronger.

    If you're not in ketosis, then your body won't be fat adapted and burning ketones for fuel. So, you're got two issues here. If it's a low intensity exercise where your body can provide adequate oxygen to the cells for aerobic respiration, your body will burn more fat versus muscle (activities like walking and hiking) once you work through your blood glucose and glycogen stores. Aim for 60-70% of maximum heart rate (often called the "fat burning zone"). This is one reason walking for 30 mins or so first thing the morning (before eating) is recommended to burn fat.

    However, if you're doing higher intensity working out -- like running, jogging, etc. -- your body will not be able to breakdown fat quick enough for energy and will start to break down more muscle. This is usually in the "cardiovascular zone" -- 70-80% of maximum heart rate. You'll burn more overall calories here, but a larger percentage of the tissue break down to provide energy to your body will be from muscle rather than fat. You often will "bonk" when you get to this point once your blood glucose and glycogen stores are gone, but it varies for each individual.

    If you're even higher (80%+ of maximum heart rate), you'll go into anaerobic cellular respiration where lactic acid will build up in your cells, causing cramping and you won't be able to keep up energy needs due to the lack of oxygen getting to the cells quickly enough -- this is why you need breaks between sprints or heavy lifting. And many who do so on an empty stomach, will likewise "bonk" as in the above example.

    So then low or no carbs after workout? Would that result in my body using up fat for energy?

    You should eat carbs before a workout and protein after. Carbs give you the energy to work hard.

    If you're getting in a good work out, recovery drink is essential. 1:4 ratio of protein to easily digested carbs is ideal. The carbs replenish your glycogen stores so your body can use the protein to rebuild your muscle during heavy lifting or prolonged cardio exertion. Chocolate milk is a poor man's recovery drink -- has almost the ideal ratio of carbs versus protein.

    So what's the solution here..I'm trying to loose belly fat..my current diet consists of 30% protien 20% fats(good) and 50% carbs..I'm just worried that by consuming 50% carbs I might not be giving a chance to my body to use up the fat cells for energy..I am on a 500 deficit though

    Someone has too many accounts and too much time on their hands.

    You are way over thinking it. Your body doesn't need any special measures to burn fat - just a calorie deficit.

    When you exercise you will burn a blend of glycogen and fat in different proportions dependant on intensity but your calorie deficit will determine how much weight (fat) you lose over time.

    Carbs cannot make you fat if you are in a calorie deficit.

    Belly fat will go along with all the other fat on your body.

    I started having a protein shake for breakfast and noticed an increase in my energy during my workout...the shake does have carbs but I think a nice balance helped me. Being able to give your all during your session will in the end burn more

    Previously I was having a wheat english muffin and egg - I would lose my drive half way through.

    Why even track carbs?

    As a diabetic I keep close track of my carbs. I find that I need some sort of carbs before a workout to fuel it. If I don't, it will make me sick.

    I think you should do some test runs and see what works best for you!
