There are many studies on fasting at home and abroad. Although they are all small samples, the conclusions are basically the same. It is believed that fasting has a good therapeutic effect on diabetes, hyperlipidemia, hypertension, obesity and other metabolic diseases. At the same time, some studies have proved that fasting can be delayed, as the name implies. The method of light diet is not only effective, but also will not harm people's health and affect people's quality of life. The specific implementation method of fast food diet is to maintain normal eating habits five days a week, but of course you can't eat too much. In addition, the "hunger" of fast food is short and intermittent. You don't need to calculate calories when eating, but eat less deliberately. This is not only more satisfying, easy to adhere to for a long time, but also as much as you want, and it is not easy to lack nutrition.

In short, FMD is actually a fast food for five consecutive days, with only about 600 kilocalories per day. Some foreign doctors use it to treat metabolic diseases such as diabetes. The remaining five days are free to eat and unrestrained. With the development of the times, great changes have taken place in our eating habits. Eating and drinking all day has become the "normal state" of our lives, and the energy intake every day is generally beyond the standard. Fast food caters to the low calorie of modern people's diet, mainly four highs and two lows. Four high diets are high in energy, calories, fat, sugar and oil. The two lows are lack of exercise and lack of sleep. It is precisely because of this diet structure and unhealthy lifestyle that many basic metabolic diseases are gradually fasted for a period of time 1-3 days. Some people are suitable for once a week, while others are suitable for once a month, on the premise that they don't feel unwell.

In fasting days, we should reduce the salt intake and adopt low-salt cooking methods, such as putting salt later and replacing salty taste with sour taste. At the same time, you can eat foods rich in calcium and magnesium in moderation, such as skim milk and nuts. Only once a day, usually from noon 12 to 3 pm. This is the most obvious method in the short-term "fast food" method! Generally speaking, 24-hour fast food is eaten 2-3 times a week.
