So how are you going to be sure you’re correctly fueled even in case you’re not hungry?
Your optimum fueling technique is extremely individualized, Starla Garcia, RD, a Houston-based dietitian and marathoner, tells SELF. Whereas your physique can at all times profit from refueling after any exercise, there are, nonetheless, three questions that may allow you to decide whether or not you want meals ASAP.

What to do earlier than a exercise
In the event you’re understanding lengthy or laborious within the morning, it’s vital to have one thing for breakfast, says Garcia—even in case you don’t get up hungry.
Morning pre-workout gasoline turns into much more very important in case you slept poorly the night time earlier than, says Garcia. Cortisol, your physique’s major stress hormone, is of course elevated proper while you get up—and it may be even larger in case you’re sleep-deprived. As a part of the “battle or flight” response, cortisol triggers the discharge of glucose into your bloodstream (so that you’ll be able to “battle”), which suggests you’re going into your exercise with elevated blood sugar. When you begin exercising, “your blood sugar goes to drop instantly,” which can lead to points like decreased vitality, mind fog, and irritability, says Garcia. All of this can be a completely pure physiological response to train and your circadian rhythm, however the results turn out to be amplified in case you’re including in intense train on high of them.
However consuming earlier than your exercise, significantly one thing carb-y with a little bit protein in it, helps hold your blood sugar secure for longer, which may translate to extra even, sustained vitality and higher efficiency, Garcia explains.
