This statement was put forward by British scientists, because the main reason of human obesity is the role of sugar substances such as starch. But not all carbohydrates can make people gain weight. For example, cellulose is a kind of carbohydrate that won't make people gain weight. There is also a kind of carbohydrate-resistant carbohydrate. This kind of resistant carbohydrate is difficult for the body to absorb, so the principle is similar to cellulose. Although you eat so much, your absorption is actually very limited.

so who is this resistant carbohydrate? Let me analyze it for you at the micro level. The structure of normal carbohydrates is a long string of sugar molecules. The resistant compounds are molecular clusters one by one. These molecular groups not only contain sugars, but also a large number of fatty substances, which stick together and are difficult to be directly digested by digestive enzymes in the human body. People will find ways to avoid difficult problems, and so will digestive enzymes in the body. When digestive enzymes find that these molecular clusters can't be processed, they will push them away and give them to the digestive organs below.

this is actually determined by the characteristics of enzymes. Enzyme is a kind of catalyst for biochemical reaction, which is characterized by small amount but high catalytic efficiency. Moreover, the enzyme does not participate in the reaction, but only needs to contact with the corresponding substances, which can improve the reaction degree. However, the premise is to contact, and there is everything on the split group, so the area of enzyme contact is small, so the catalytic efficiency is low. An enzyme can only catalyze one reaction. Such as alcohol dehydrogenase and acetaldehyde dehydrogenase. Alcohol dehydrogenase is only responsible for converting ethanol into acetaldehyde, and acetaldehyde is responsible for the process of converting acetaldehyde into acetic acid. No matter how much acetaldehyde accumulates, alcohol dehydrogenase will not care.

so how do you get resistant carbohydrates? Take bread for example. Under normal circumstances, you can choose to use brown bread-whole wheat bread. The flour used in whole wheat bread is not so fine, so as long as you eat serious black bread, you won't get fat. Because there are too many fibers in it that human beings can't digest and absorb. If you don't have brown bread on hand, you can put it in the freezer of the refrigerator, freeze it, take it out overnight, and thaw it in the oven or other equipment, so that the content of resistant carbohydrates in white bread will be much higher.

to put it bluntly, losing weight is very simple-it is to ensure that the energy you consume every day is greater than the energy you consume. And many people say that it takes more than an hour to lose weight after exercise, which is wrong. When you start running, your body has already begun to consume energy. And for weight loss, practice three points and eat seven points. I used to eat a lot of vegetables every day, such as broccoli, Shanghai green and lettuce. Vegetables account for about 61%, and 15% of the remaining 41% are fruits. Finally, there are various trace elements and carbohydrates. Carbohydrate is not a poison, but a serious nutrient. You should eat it every day.
