How long should I wait to exercise after eating?
How long after eating should I wait to exercise, or does it not matter? I am mainly talking about cardio, not weightlifting. I am trying to lose weight, not gain it, and in large amounts.
Also you should say what is your "destination": losing weight, or gaining it ?
Do you have any bad experiences with working out directly after eating? Any reasons why you don't work out before eating? Have you found any information yourself, that was conflicting? Based on this information, I can only give you the same answer @bonhoffer and @Michael has given you.
I would ask your doctor or dietitian it is good to get the advice of an expert I am also looking for this answer and there is just too many variables some web sites say eat on an empty stomach some say don't better to get an expert answer so that you can make an informed choice
It takes 30 to 40 minutes for food to digest in your stomach and 3 to 4 hours for it to absorb in your intestines. I agree that there is no strict formula for this, since it also depends on what you eat and how you intend to expend that energy.
From my experience if I eat a large meal which is heavy in carbohydrates I see my best performance with a high intensity exercise 6 to 8 hours later. I have also consumed protein shakes within 15 minutes of a weight training circuit and have seen strengthened results. I recommend you experiment and find your own ideal wait length.
