There are many possible reasons why losing weight does not change your body shape-the sudden decline of physical health level, the inconspicuous change of body circumference and so on. But for people who lose weight, the biggest possibility is that you have used radical methods to lose weight, so that losing weight is mainly due to muscle loss and water reduction, not fat reduction, so although you have lost weight, your body looks little changed. With the same mass of fat and muscle, the volume of fat is almost four times that of muscle, so when muscle is lost, the impact on appearance is basically small, but it has a great impact on weight. If this is the case, then you should adjust your thinking of losing weight as soon as possible, because muscle is the main place of energy consumption, which is directly related to the level of metabolism (that is, daily energy consumption). If muscle loss and consumption are reduced, then your next step will be to lose weight slowly or even rebound, because the accumulation speed of fat far exceeds the synthesis speed of muscle. And if you use radical methods to temporarily reduce water in your body (such as the three-meal apple method), your weight will rebound with the supplement of water in your body. It can be said that these two practices have no positive effect on weight loss, and they are also what we need to avoid to lose weight. Only by combining proper diet control with proper exercise can we really lose fat, make our body slimmer and healthier, and make a good change in weight and body shape. Mint fitness expert group
