Losing weight and losing weight are not necessarily the same thing. If you lose weight by starving, it is a diet. Because the body can't get the basic nutrition needed to maintain the normal operation of the body, the body will break down its own fat and muscles into sugar to provide energy for the body. There is more fat in the chest, and the parts with more fat accumulation will become thinner when the fat is decomposed, and the chest will of course become smaller. This method "loses weight" at the same time, the body will reduce metabolism to reduce calorie consumption. At this time, weight loss is caused by muscle and fat decomposition. This situation is actually very harmful to health, so this "weight loss" method is strongly recommended. And this way of losing weight leads to the decrease of basal metabolism. Once you return to a normal diet, you will even get fat, because you have consumed more calories than your body needs, and most of them are fat. It will be more difficult to lose weight in the future. It is not difficult to lose weight healthily. You can lose weight easily by doing three things. First, improve your diet. Eat high-quality protein fruits and vegetables with high dietary fiber and low calorie (not fruit and vegetable juice) for three meals a day and then drink more water (that is, ordinary white water is not a drink or even milk tea outside the chart). The second is proper exercise. Choose an aerobic exercise that you feel a little tired but can continue to exercise for half an hour to an hour at a time, such as jogging, brisk walking, swimming (swimming can be done first if possible, because you can mobilize many muscle groups, and the burden on your knees is small), skipping rope, etc., and you can exercise for about 45 minutes at a relatively fixed time every day (you can moderately increase the daily exercise or increase the number of times if you have spare capacity); The third is to ensure regular and adequate sleep every day. Above three points, you can form a habit, stick to it and lose weight easily.
