In the process of exercise, the body will not consume fat at first, but mainly glycogen. Only when the exercise time reaches about 30 minutes, will it begin to consume fat mainly. Then, some people think that if I eat little or nothing, the calorie intake is low, which makes my body hungry and naturally consumes fat. Theoretically, it can burn fat.
When the body is hungry, the body will start the protection mechanism to protect the fat from accumulating energy out of instinctive reaction. This reaction is to prevent you from starving quickly in extreme famine. So the answer is clear. When the body is hungry, it mainly consumes not fat, but muscle, and fat only consumes a small amount.
Most people who go on a diet to lose weight, although they lose weight quickly in the early stage, are only "illusions". What they really lose is not fat, but muscle and water. After consuming a lot of muscles, the body's metabolic ability is reduced, and the overall figure doesn't look so thin. When you can't control your diet and start eating, it is inevitable to gain weight because your metabolic ability is reduced.
Excessive calorie intake will cause obesity; Too little calorie intake leads to a decrease in metabolic capacity and a fat constitution. So, what can we do to lose weight better?
Controlling diet is the key to losing weight!
So how to eat it is suitable? The fat-reducing diet should conform to the calorie intake in one day and should not be lower than the basic metabolism of the body; At the same time, it can't be higher than the total amount of calories consumed by the body in one day.
How to calculate basal metabolism? The formula is as follows:
Female basal metabolic rate =66 1+9.6* weight (kg)+ 1.72* height (cm)-4.7* age.
Male basal metabolic rate =67+ 13.73* weight (kg)+5* height (cm)-6.9* age.
In general, men have more muscles than women, so the basic metabolic capacity of men is higher than that of women.
