Does your body burn fat if you don't eat?

With enough time and dedication, fat stores will disappear. The body burns calories from food and beverages to boost physical activities. However, when you consume more calories than you need, you store the excess as body fat for future use. Conversely, when you eat fewer calories than you need, your body burns stored fat for energy.

Not eating doesn't directly lead to weight gain; in fact, you can lose weight because you'll temporarily eat fewer calories than you burn. The problem is that fasting is unsustainable, so any weight-loss benefit is likely to be short-lived and your health pays the price. Fat burning usually begins after approximately 12 hours of fasting and intensifies between 16 and 24 hours of fasting. Skipping meals is not a good idea.

To lose weight and keep it off, you must reduce the amount of calories you consume and increase the calories you burn when you exercise. However, skipping meals altogether can cause tiredness and can mean that essential nutrients are lost. You're also more likely to eat snacks that are high in fat and sugar, which could lead to weight gain. In addition to reducing body weight, this fast can help lower cholesterol, improve glucose control, reduce liver fat and improve blood pressure.

It prepares the body to gain fat more easily in the long term and reduces BMR, making it difficult for the body to do what it naturally does: burn calories for energy. This is because the body is now prepared to replenish lost fat stores, not lean muscle, which is lost during starvation. Foods labeled as low fat must not contain more than a specific amount of fat to legally use that label. For example, a moderately active 145-pound person burns about 2,175 calories per day and will burn 1 pound of fat per week by consuming 1,675 calories per day.

Foods that contain fat, protein, or carbohydrates contain calories, which are used as fuel for physical activities. Similarly, a study in mice found that lean mass and lean muscle mass were sacrificed during starvation; however, body fat stores were relatively the same in mice on a control diet and in obese mice on starvation diets. Conversely, the body draws on those fat stores for energy when it doesn't consume enough calories to fuel its activities. Your body stores unused calories in fat cells for energy when you need it, so you gain weight when you overeat.

Choose fruits or vegetables instead of chips, chocolate, and other snacks that are high in sugar, salt, and fat. While it may seem logical that cutting more calories leads to greater fat loss, this isn't always the case. Therefore, focusing on body composition, rather than fat loss, can help you improve your overall appearance and reduce body fat while increasing strength. In addition, once a person returns to a normal caloric range, they can often experience collateral fattening, in which weight loss leads to overeating until regaining fat.
