What should I do if I suddenly lose weight? Is the god of knowledge flustered?

Since you exercise, you have to explain why and what is bad for your health. The reason why I don't know my weight may be because I have entered a platform period, or it may be because dieting can't provide the calories needed by the body's basic metabolism. Losing weight is a metabolic process. If you go on a diet and you can't provide the calories you need for metabolism, then your body's metabolism will slow down. If it is a platform period, don't worry, it is normal. Adjust the mentality and increase the amount of exercise appropriately. Don't limit yourself to your weight, it's actually good to have a thinner waist. Of course, I suggest that you resume your diet and at least ensure your basal metabolic calorie intake and nutritional balance. You know, if the body lacks a certain nutrient, it will affect weight loss, and even this nutrient includes fat. Therefore, a normal diet is better. Drinking a glass of slimming tea half an hour after a meal can promote fat metabolism, which will also help you get through this stage.
