Is it OK to workout when hungry? Working out on an empty stomach won’t hurt you—and it may actually help, depending on your goal. But first, the downsides. Exercising before eating comes with the risk of “bonking”—the actual sports term for feeling lethargic or light-headed due to low blood sugar.
Should you be hungry before a workout? Having a snack before a high-intensity workout is definitely recommended if you haven’t had a meal or snack for a while. You need enough energy to get through the workout, and you risk getting injured or working below your peak abilities if you lack sufficient energy stores.
Does staying hungry burn fat? Missing meals and going hungry can shift your metabolism so it stores fat instead of burning it. This doesn’t happen in a day of missing meals, but if you skip meals for several days and severely lower your caloric intake, your body uses a famine response to conserve energy.
Can I workout empty stomach? While there’s some research to support working out on an empty stomach, it doesn’t necessarily mean that it’s ideal. When you exercise on an empty stomach, you may burn valuable energy sources and have less stamina. Low blood sugar levels may also leave you feeling lightheaded, nauseous, or shaky.
