The key lies in the basal metabolic rate of the body, that is, the energy that the body must consume to maintain normal physiological activities when it is inactive all day. The energy of this basic metabolism plus the energy consumed by all activities every day, including walking, doing housework, exercising, etc. , is a person's daily necessary calories. The basis of diet diet is to make the daily intake of calories lower than the daily consumption of calories, and slowly consume the accumulated fat, so as to achieve the purpose of losing weight.

However, the human body is a very "precise instrument". When dieting or even fasting, because the calorie intake is lower than the need to maintain normal physiological function, after a period of time, the body will actively adjust the basal metabolic rate downwards, that is to say, for example, your daily calorie requirement may be 1500 calories. If you only eat 1200 calories a day because of dieting, you will lose weight at first, but go on a diet. The body will adjust the daily demand to 1000 calories. At this time, if you still consume 1200 calories every day, your weight will stagnate or even increase because the calories you consume are greater than the calories you need to consume. This is the main reason why dieters or dieters can't lose weight after losing weight to a certain extent.

Therefore, it is still an old saying that "eat less calories and exercise more" is the only way to lose weight. After you achieve a goal through dieting, if you want to maintain your weight or lose weight further, the best way is not only to continue dieting, but also to remember to keep regular exercise, because exercise can not only consume calories, but also improve the body's basal metabolic rate, so as to ensure that the calories consumed during dieting can be lower than the calories consumed, thus losing weight successfully.
