Does the Body Burn Fat When You Are Hungry?

Your body stores fat as a way to help protect you against starvation if you can’t take in enough food. However, your fat reserve isn’t the first place your body goes for food. Instead, it reaches out for sugar for energy. 1.

Hunger is normally a reflection that your body has used up energy from recent food you ate and has moved onto getting energy from sugar in your blood. 2. The more sugar you take in, the more fuel your body has to use before it reaches out to the fat stores. If your body doesn’t have enough sugar to supply the energy it needs, it begins to burn fat when you’re hungry instead.

Missing meals and going hungry can change your metabolism (新陈代谢) so it stores fat instead of burning it. 3. However, if you skip meals for several days and severely lower your calorie (卡路里) intake, your body begins to store as much fat as possible.

4. Your body burns up sugar stored in your system and begins to burn fat as you continue to exercise. However, exercising when you’re hungry won’t help you burn fat faster. A recent study shows that the body burns the same amount of fat regardless of whether you are hungry when you exercise.

Staying hungry all day won’t necessarily help you burn fat, but cutting calories is key to losing weight. 5. Snack (吃点心) in between meals to keep your metabolism working all day, which helps it burn more fat than if it’s allowed to slow down when it’s not meal time. Snacking in between meals can help you control your meal sizes at meal time.

A. Exercise is key to burning fat.

B. You shouldn’t cut out food to cut calories.

C. This doesn’t happen in a day of missing meals.

D. Just being hungry doesn’t mean your body is burning fat.

E. If you take in less food than your body burns, you’ll lose weight.

F. Your body stores sugar in case you need it when you feel hungry.

G. Eat five or six small meals throughout the day instead of three large ones.
