Many people who lose weight in terms of exercise are more inclined to aerobic exercise, for the strength of the exercise to much less, because aerobic exercise can be carried out for a longer period of time, can consume more energy, but also to bring themselves a stronger sense of satisfaction, while strength training slow, easy fatigue, ignored by many dieters, but for weight loss, these two exercises are actually very important. Although aerobic exercise can consume body fat, but also will break down the body’s muscle, and muscle is an important part of energy consumption, muscle loss also means a decline in the basal metabolic rate, which is very detrimental to long-term weight loss. Strength training can make up for the muscle loss from aerobic exercise and maintain the body’s basal metabolic rate, while also providing a plastic effect. In the Chinese Guidelines for the Surgical Treatment of Obesity and Diabetes (2019), it is stipulated that obese people should perform at least two to three times of strength training per week in addition to no less than 150 minutes of aerobic exercise after weight loss metabolic surgery to avoid muscle loss and affect the weight loss effect. The health managers at weight loss metabolic centers such as Youdao Doctor Group will also advise patients to work out appropriately after six months of basic body recovery from surgery, which has the effect of shaping and preventing skin laxity, in addition to enhancing weight loss results. Just as it is difficult to achieve satisfactory weight loss with dieting alone, aerobic exercise alone often works only at first, and needs to be combined with strength training and diet control for effective long-term weight loss.
