When it comes to eating before exercise, it's all about timing. No matter what time of day you choose to exercise, make sure to plan your workout two to three hours after your meal. Going overboard with too much food right before a workout will leave you feeling sluggish and can lead to stomach discomfort.
Regarding this, is it OK to exercise after breakfast?
The best time to work out, Vigil said, is before you eat. A post-exercise nutrition program helps recovery and minimizes muscle damage, Virgil said. However, if your schedule demands you eat first, Vigil suggestsed waiting an hour or two after your meal before exercising. That will allow the stomach to empty out.
How long after breakfast can you run?
Wait Time and Meal Size. How long you should wait to run depends on how much you've eaten and your own digestive system. As a general rule, give yourself at least an hour after a small snack, two to three hours after a small meal and three to four hours after a large meal.
