First of all, it is certain that if a person consumes 3000 calories a day, no matter what he eats and how the nutrients are matched, if the total calorie intake is only 2300 calories, he will never gain weight, but in the long run, his basal metabolism will be reduced, which will make it difficult to lose weight.

Secondly, let's look at the nutrition ratio. If the total calorie intake per day is limited to 2300 calories

1. When the nutrition ratio is balanced, you can achieve the effect of losing weight, because the calories are consumed after intake, which is not enough, and there are still 700 calories left, then your body will mobilize glycogen and fat to get calories.

2. When the source of 2300 calories is fat. As we all know, fat is easier to be stored in its original form, instead of being converted into sugar or protein, and your body needs not only fat, but also nutrients in sugar and protein every day. At this time, the body will obtain these nutrients through other channels, and the excess fat will be stored, but the sugar and protein obtained by the body through other channels also need heat energy to maintain the supply, which will mobilize fat and decompose fat to obtain energy.

Therefore, compared with the two, eating a balanced diet is easier to lose weight.
