The method of improving metabolism level by low metabolism needs to be chosen according to the cause of low metabolism. If the low metabolism is caused by disease factors such as hypothyroidism, medication can be chosen to increase the metabolism level; if the low metabolism is caused by lack of exercise or improper diet, the metabolism level can be improved by adjusting the diet and increasing exercise. 1. Hypothyroidism is a generalized low metabolism syndrome caused by hypothyroidism or thyroid hormone resistance due to various reasons. Low metabolism can be improved by taking levothyroxine and other medications for replacement therapy. 2. Low metabolism caused by non-disease factors can be improved by improving lifestyle, regular work and rest, increasing protein intake, and reducing carbohydrate and fat intake. In addition, regular exercise is needed to enhance cardiorespiratory fitness, which is conducive to improving metabolism. Patients with low metabolism can consult their doctors for treatment if necessary.
