1. Copenhagen diet: The Copenhagen diet will require dieters to strictly control their diet according to a 13-day diet. The standard breakfast is black coffee and toast, and a piece of toast can be added in a few days; Lunch is usually 2 grams of ham, cod or two boiled eggs, which can be accompanied by vegetables; For dinner, there are 2 grams of steak, 25 grams of chicken and so on, and there are unlimited vegetables. The diet in Copenhagen is very strict. If you eat food outside the diet, you need to stop the diet for a while before you can start again. Because of the high proportion of meat in the diet menu, it is the first choice for meat eaters to slim down.

2. Atkins diet: Atkins diet was put forward by Dr. Atkins in the United States in 1972. He believed that the culprit of obesity was carbohydrates, so he encouraged eating less starch and more meat. The specific operation can be divided into several stages: in the first two weeks, you can only eat no more than 2 grams of carbohydrates every day, most of which come from vegetables, and you can eat any amount of meat and fat; Next, the intake of carbohydrates will be appropriately increased until the weight loss goal is achieved; After that, the intake of carbohydrates should be kept at the level when the weight loss goal is achieved. It is more complicated than the Copenhagen diet, but it is also popular with meat dieters.

3. No food after noon: No food after noon comes from Buddhist precepts. When people lose weight by this method, they usually only eat breakfast and lunch two times a day, and stop eating two to three hours after lunch. This method requires a good breakfast and a full lunch, and the principle is that two meals must be full. After lunch, I stop eating except water, tea and low-calorie drinks. Sometimes you are so hungry at night that you can eat a little low-calorie fruit. This method can basically be completed by controlling the diet every afternoon and evening, which is convenient and fast, so it is very popular among white-collar workers.

4. fast food to lose weight: fast food means normal diet for 5 days a week and fast food for 2 days. The fasting days are discontinuous, usually Monday and Thursday, requiring women to consume less than 5 kilocalories and men to consume less than 6 kilocalories. On fasting day, it is recommended to eat foods with high protein content and low glycemic index, and only eat breakfast and dinner. For example, the theory recommended a diet for men's fasting day, with yogurt, banana slices, strawberries, blueberries and almonds for breakfast, shrimp, watercress, avocado salad and a mandarin orange for dinner, with a total amount of 599 kcal. Supporters of fasting diet believe that this method of losing weight is not as unacceptable as complete fasting, but also can repair the body by fasting and achieve the so-called "detoxification and weight loss" effect.

5. Diet-only diet: This kind of diet suggests eating a lot of certain foods for a period of time, and only a small amount of them are matched with other foods. There are many kinds of such diet methods, such as "three-day apple diet", "cucumber and egg diet", "boiled egg diet" and "7-day vegetable slimming soup". Or, like the "apple diet", eat only apples within three days; Or, like the last few, for a period of time, take specific food as the staple food. The diet menu of every meal every day is defined very simply and rudely, because it is too simple, it will be chosen and used by most first-time dieters.
