According to the western standard theory of female manikin, about 36% of a person's body weight is muscle, 9%- 15% is essential fat, 15% is stored fat, 12% is bone, and about 25% is other tissues, including internal organs, skin and blood. Therefore, except for people who are particularly fat, the proportion of fat in people's weight is generally a minority. Most of our weight is not fat, but lean. So, lose weight without losing weight, lose weight without losing weight. Only reducing fat is called losing weight.
