Exercise - Before or After You Eat

Until tonight I have always exercised before eating and incorporated meals into refueling my body. Tonight I ate, left it a couple of hours and worked out and gave me the worst heartburn. I think you just need to try what's best for you and your body and what you can fit in.all exercise is better than none and everyone's body is different.

It doesn't matter how long or how intensely I work out (or actually, maybe it'd make it worse) - I cannot eat within the hour before working out.

I workout in the AM fasted and generally fast 3 hours before my evening karate class. If I'm feeling very hungry, I'll have a banana or something.

I think it really depends on you. If you're feeling faint while working out, try to eat something before hand - something light, quick, ideally something you can eat in the car maybe. I find a banana does the trick for me, or a piece of cheese and toast if I'm peckish for something salty. But if eating before hand makes you feel gross while working out, see if eating after is an option - or if you have no appetite/time after you work out, you might find "skipping" that last meal and adding the calories elsewhere in the day more sustainable (i.e. Intermittent Fasting).

It is a preference thing. Sometimes I eat beforehand and sometimes I do not. Sometimes I eat during my workout (today I ate a banana between sets.)

I generally find that if I am doing cardio for 40 minutes or less, I am fine to go without eating first thing in the morning. If I go for longer, I like to eat something like a banana or granola bar (something in the 100-150 calorie range.) Most of the time I can weight train without eating but the workout I did today is my most intense and it was nice having a snack during it.

Long story short--it's a preference thing and you'll kind of figure it out through trial and error.

Totally up to the individual. Personally, I'm useless before I eat, I can barely walk 3 flights of stairs that later in the day I can jog up. Others get great results from exercising fasted.

Whatever scientific advantages they may or may not be, I think they would be outweighed by the individual's personal preferences because you will do better when you do it your way.

Yes

It's a matter of preference.

For me, when I lift weights, I like to do it on an empty stomach.

When I do cardio, I need to have some food in my stomach or I feel ill.

Figure out what works best for you.

It depends........ Here is some recommendation from my GYM

What should I eat before/after a workout?
It depends on lot of things. Here it is one at a time.
1 – Type of workout. If the workout will cause you to have an elevated heart rate, lots of sweating, requires lots of effort, then you will not want to eat within 2-3 hours prior (amount of time depends on how you feel during workout after food). Stick to calorie free beverages – water, coffee, tea (unless one of these upset your stomach).
2 – Time of workout. Follow the directions above if the workout is late enough in the day to allow you to eat food prior. If it is early morning, then get up, drink some water, maybe some electrolytes (ultima), and hit the workout.
3 – Weight Training. If the workout is not a heavy breather, or one that will not cause an elevated heart rate for a prolonged period of time (i.e. Deadlift, 3-3-3-3-3), then you can eat as close to the workout as you like – again, as long as you feel good throughout the workout.
4 – Things to avoid prior to a workout. Avoid foods that will cause an irregular pattern in your blood sugar. For most of you that will be foods that are high glycemic (i.e. pineapple, banana, most grains, flavoured yogurt, food bars, sugary drinks, etc.). For others this may involve not eating too much fat (oils, nuts, seeds, avacoados, etc) or protein (animal foods, dairy, eggs, etc.) prior. Just take note of what makes you feel good. Another suggestion would be to avoid dairy foods prior to any heavy breathing workout as it may cause an excessive amount of mucous for many people –… that is not a good thing.
5 – After the Workout. You will want to choose the ratios of food (protein/fat/carbohydrate) you consume based on your body fat %. For an estimate, unless you can see you abdominal muscles you are going to be higher than 12-13%. This is your starting point. If the workout is a weight training workout, then eating a balance of protein, fat, and carbohydrates within one hour following will be optimal. The higher your body fat (greater than 13%), the less carbohydrates (less than 10-15 grams) you should consume (on a linear relationship – the higher the body fat %, the lower the carbohydrates) after this type of workout. If the workout is a heavy breather of long duration (greater than 7-10 mins) with lots of sweating, you will want to consume quality protein and carbohydrate dominant foods. For most, avoiding fat is not practical as it will help you for the rest of the day. Again, if your body fat is higher, then the less carbohydrates you should consume (under 20-25 grams). The exact amounts and types of food will depend on lots of things (your body mass, body fat %, food tolerance, activity level, schedule, experience with training, etc.).

And sometimes during.
