Night Listening | The faster you lose weight, the more you gain back! This means your basal metabolic rate has decreased

Hello, this is Science Popularization China. I don't know if you have ever had the experience of losing weight. Now I recall that the whole process is long and difficult, and it is easy to rebound. This kind of weight loss rebound is like knocking down a building block that has been built with great difficulty. It is a great blow to people. But why is it so easy to rebound after losing weight? Let's talk about it today.

In fact, the most direct explanation is that we have not been able to stick to good eating and exercise habits. If we go deeper, it is because our basal metabolic rate has decreased.

The basal metabolic rate of the human body refers to the minimum energy requirement of all organs of the human body to maintain life. Generally speaking, the basal metabolism of a healthy adult is 1000 to 1200 calories per day. So even if we lie still, the body will consume calories. Of course, each person's basal metabolic rate will be slightly different, and will be affected by age, gender, ambient temperature, nutrition, physical function and other factors.

A paper published in the journal Obesity in 2016 mentioned that losing weight will cause the body to deviate from its actual weight, and the body's basal metabolic rate will also change accordingly. In this way, after losing weight, the basal metabolic rate will become lower than before. If you do not continue to maintain a healthy diet and regular exercise, it may cause fat accumulation, and your weight will naturally "rebound".

So how can you increase your basal metabolic rate? Exercise is a good way. Regular exercise not only increases the calorie consumption during exercise, but also consumes more calories when you are resting. So exercise is not only easier to lose weight, but also easier to maintain your body shape.

The most important point is: if obesity affects your health and life, then while actively losing weight, you must pay attention to gradual progress and gradually increase the amount of exercise while maintaining good health.
