The main cause of obesity is metabolic diseases. The metabolic problem is that cells lack nutrition, which leads to the decline of cell vitality. After the cell vitality decreases, the work efficiency of spleen and kidney tends to decrease, and the metabolic cycle of cells is 2 1 day to 30 days. Nutritional therapy needs to adopt professional nutritional formula, supplement cellular nutrition within 42 days, improve the self-healing ability of cells, and the metabolic problems of obese patients will be restored. All metabolic diseases are caused by the decline of self-healing ability of cells. After the self-healing ability of cells is improved, metabolism will return to normal. Even after 42 days of nutritional therapy, we need a reasonable diet and moderate exercise to keep our cells and bodies in the best condition!
