The difference between health care and fitness can be taken as an example: the theory of fitness and weight loss says that obesity is converted into fat through excessive intake of calories, so it is necessary to continuously consume calories to achieve the purpose of reducing fat. However, health care believes that obesity is caused by insufficient energy or blocked detoxification channels, and the accumulation of body garbage and waste. Therefore, to reduce fat, it is necessary to dredge the meridians first, then make up for the deficiency of qi and blood and discharge garbage. The content of fitness is only a small part of health preservation. However, fitness only considers this small part, ignoring the natural way of keeping in good health, making fitness a short-term effective and long-term unhelpful behavior. Health care includes walking, sitting, eating and living, as well as exercise and lifestyle.
