Losing weight does not mean losing fat. We should put a scale that can measure body fat rate at home. Next, we have to bargain for the lost weight. Have you lost any fat or muscle? Remind you to remember: the goal of slimming is to reduce fat, not muscle! The truth behind dieting to lose weight is that before implementing the weight loss plan, your weight record was 50 kg and your body fat rate was 30%. When you start your devil's diet, you may take diet pills, starve yourself, or refuse any starchy food, but like most people, you are just too lazy to exercise. Two months later, on the weighing scale at the station, you saw that you lost 3 kilograms, but your body fat rate was still 30%. The figure of body fat rate is so stubborn that I believe many people who lose weight have learned it. It's really an eyesore to see it fixed there and unable to fall off. Let's calculate the above example, Look at the changes of body composition before and after losing weight: before losing weight: body fat weight: 50kg * 30% = 15kg LBM weight: 50kg- 15kg = 35kg: after losing weight: body fat weight: 47kg * 30% =14./kloc-0. After two months of diet adjustment and exercise training, her weight was 47 kg, but her body fat rate dropped to 25%. It is difficult to achieve this effect by diet control alone. We can calculate her figure changes: before losing weight: after losing weight: body fat weight: 50 kg *30%= 15 kg body fat weight: 47kg * 25% =1/0.75kg LBM weight: 50kg-15kg = 30.
