Why does losing weight make me less happy?

Nowadays, many girls feel fat no matter how thin they look. When they eat snacks, they are afraid of gaining weight. They have a heart to lose weight, but they have a mouth to eat and a stomach to fill. But do they really need to lose weight? Did you lose weight successfully? How to judge whether you are in a healthy weight range?

Let's take a look at what weight loss is. Some girls around me stare at their weight every day, saying that they will be happy if they lose a pound, and they will regret if they eat two pounds. I used to be like that, and I was really distressed by girls who lost weight. Is it necessary? It is normal for a person to weigh 2 ~ 4 kg every morning and evening, including the amount of water he drinks, the amount of food he eats, and the food residue he does not absorb or exclude. This also denies the saying that' losing weight is losing weight'.

The ultimate goal of weight loss is to reduce body fat rate and internal fat rate to the standard range, and improve muscle mass, water content and basal metabolism. We all know the volume difference between a catty of fat and a catty of muscle (see the picture below, image source network). Why do some girls lose 10 kg, but there seems to be no obvious change? If you want to know what this 10 kg is, it is probably 5 kg of water and 3 kg of muscle, and the fat really lost is even minimal.

Having made this clear, girls who really want to lose weight in the future should pay more attention to the changes of body circumference instead of the changes in the numbers on the weighing scale.

Let's talk about whether girls who don't look fat and whose body mass index is within the standard range need to lose weight. For example, sy is 162 and weighs 52.6kg, so the result of body mass index is 20, which is within the range of 18.5 ~ 23.9 according to the reference standard of body mass index of China people, so it seems that 20 is still a very healthy indicator. However, the body mass index is only a reference value to measure the degree of obesity. Through the measurement of professional body fat scale, the body fat rate of sy is as high as 28.5 (standard range 16 ~ 28) and the muscle rate is 3 1.4 (standard range 3 1.5 ~ 45.5), which is not optimistic. High body fat is the invisible killer of the body and the chief culprit of cardiovascular and cerebrovascular diseases such as coronary heart disease. Low muscle rate means that the body consumes less calories. Eating the same amount of food will consume fewer calories than people with high muscle mass. If it can't be consumed, it will be converted into fat storage, which will affect basal metabolism.

In this way, although sy's weight and body mass index are normal, it still needs to lose weight. Here' fat' refers to subcutaneous fat. Only by reducing body fat rate and increasing muscle rate can the body be in a real healthy state.

Finally, remind the little fairies who need to lose fat, don't be superstitious about some short-term slimming methods, not only will they not lose fat, but they will also lose muscle and reduce basal metabolism!
