Basis for measuring weight loss effect:
The National Institutes of Health (NIH) recommends the following four factors to evaluate the weight loss effect:
1. Has the body mass index decreased?
Body mass index (BMI) is an index closely related to body fat, which mainly reflects overweight and obesity. It is a standard widely used in the world to measure the body's fatness and health. Because the body mass index calculates the proportion of body fat, it is more accurate to measure the risk of heart disease, hypertension and other diseases because of overweight than to identify them simply by weight.
2. Has the subcutaneous fat decreased?
Waist circumference, leg circumference and arm circumference can obviously reflect the thickness of subcutaneous fat.
Measurement of fat in abdomen, scapula and lower arm: The thickness of subcutaneous fat is measured by paired measuring instruments-subcutaneous fat meter, so as to estimate the whole body fat.
3. Have you lost weight?
It is necessary to eliminate the weight loss caused by physical and psychological diseases, excessive physical expenditure and bad weight loss methods (dieting, diarrhea, etc.). ).
4. Have indicators of obesity-related diseases improved?
Such as hypertension, high LDL ("malignant") cholesterol, low HDL ("benign") cholesterol, hyperglycemia, etc.
In China, people who lose weight are mainly characterized by losing weight, and there are some misunderstandings in measuring the weight loss effect. They are used to taking weight as the only indicator to measure the weight loss effect, ignoring the evaluation of bmi index and subcutaneous fat, and even falling into the trap of bad weight loss methods.
WHO (World Health Organization) stipulates that the principle of uniform weight loss is to lose 0.5- 1 kg a week, and weight loss can only be within this range, so as not to harm the body.
The WHO (World Health Organization) three standards for healthy weight loss stipulate: no anorexia, no diarrhea and no fatigue.
