I looked up the information on the internet and didn't see the original literature. As far as Baidu Encyclopedia is concerned, as far as basic biological principles are concerned. If you eat three meals a day normally, you can't achieve the effect of reducing fat if you separate starch from protein, because the supply of fat cells is not calculated by the hour. If you don't give it protein this time, it will absorb protein in the next meal, and it won't starve to death because there is no food. At the same time, any kind of food, such as potatoes, contains a lot of carbohydrates, but also contains a certain amount of protein, so if you eat normal food, it is impossible to completely separate starch from protein.

Furthermore, after reading the principle of Baidu Encyclopedia, "If protein is always mixed with starch, your stomach will secrete different gastric enzymes to digest these two ingredients respectively, and the digestive system will be very hard and it will take you more digestion time!" There are some mistakes in this paragraph. The stomach can only secrete one enzyme, which is involved in protein's digestion. Enzymes secreted by the stomach can't digest starch. Besides, I don't agree that more digestion time is needed. First of all, after years of evolution, the digestive system should have adapted to the digestion of various foods. If you only digest a single food at this time, it may bring damage to the digestive system (for example, if you eat too much protein food, the enzymes secreted by your stomach will not be digested so much, and if you eat too much starch food for the second time, your stomach will secrete too many enzymes and waste them). ?

To sum up, I think this method is not credible. The key to lose weight is to eat less and eat more meals, ensure the balance of starch, protein and other nutrients, and exercise more. There should be no shortcuts.
