Many misconceptions surround eating and exercise. Some people avoid food before a workout because they worry they’ll get nauseated or have cramps. Others don’t eat in the morning because they think they’ll burn more fat if they move on an empty stomach. Some athletes assume that hunger pangs before practice are a good thing, because they think that their body is diverting all its energy to the workout instead of digestion.
None of these beliefs are true.
The bottom line is this: When you expend energy by exercising, you need to consume extra energy to fuel the activity. How much you should eat and at what time of day depends on the type and duration of your workout, as well as when you last ate and what was on the menu.
Ideally, how much energy your body uses (how many calories you burn) and how much energy your body takes in (how many calories you eat) should be in balance all day. Keep in mind that your body burns around 100 calories an hour at rest and during sleep, so you don’t just need energy for exercise, you need food throughout the day to fuel being alive. If you are highly active, if you eat big meals, or if you go for long periods without eating, you can upset this balance and cause extreme energy highs (surpluses) or lows (deficits.)
