Loss of appetite may be due to the lack of nutrients you normally need, decreased metabolism, and hormone secretion to make your body run in an "energy-saving state". Poor spirit, bad appetite, unhealthy. Give you some advice on how to reduce it: (1) Never go on a diet. Control your diet. Healthy eating is not dieting. Find a food calorie meter. You carefully check the calories of the food you eat every day, and then reduce high-calorie foods, such as high-fat and high-starch foods. Meanwhile, don't eat too much. It is very, very unscientific to lose weight quickly without eating. Losing weight quickly, from the perspective of Chinese medicine, is a very vital thing. As a result of losing weight quickly, your face will be poor, your skin will be wrinkled, your spirit will be haggard, your body will be weak and your weight will be uneven. Your legs and arms may be thin, but your stomach will still be T-shaped. And lose weight quickly and rebound quickly. Not eating or eating less is even more nonsense. Not to mention how your stomach and organs can stand it, I'm afraid you have lost half of your protein (muscles and organs). What you want to lose is fat, not your muscles and organs! Ensure the daily intake of 75-100g of protein. If protein is insufficient, the body will decompose the protein of your own body and organs to supplement the metabolism of the new city. Proper fat intake is also necessary, otherwise you will have hormonal disorders, such as acne, affecting reproductive function, irregular menstruation of girls and so on. If you consume less energy, your body will automatically adjust your basal metabolism, which will make you run in an "energy-saving state" and your energy and spirit will be seriously reduced. (2) Developing a good routine can make you energetic, secrete hormones well and increase your metabolic rate. (3) Insist on aerobic exercise. Buy a pair of jogging shoes, walk fast, keep the speed of 6-7 kilometers per hour, sweat, barely talk, and keep your heartbeat around 120. So walk at least five times a week for more than 40 minutes each time, and then do sit-ups for more than 60 times a day, reaching 100. In this way, your waistline can be reduced by at least 4 cm in a month. Jogging is not recommended. Jogging is too fast to persist, which has a great influence on joints. The only thing to pay attention to is to slow down when walking. Another way is to practice boxing and buy CDs to practice at home, and the effect is also very good.

(4) For the goal of weight, it is generally appropriate to lose one kilogram a week.
