Enzyme is the Japanese name for "enzyme" in Chinese and enzyme in English, which is a special protein. In nature, enzymes, like beef, are protein. Eating protein needs to be digested and broken down into amino acids, which enter the amino acid bank in the body, and then these amino acids are transported to different parts of the body and recombined into the amino acids needed in that part. Enzymes are enzymes and catalysts for biochemical reactions in our bodies. Junior high school chemistry has said that catalysts can only accelerate chemical reactions, and no amount of catalysts will change the direction and products of biochemical reactions. Therefore, as a catalyst, enzymes will not change the biochemical reactions of our bodies. Enzymes can neither break down fat nor prevent fat synthesis.
For example, digestive enzymes are a special protein in the stomach. The protein-containing food we eat is broken down into amino acids which enter the amino acid pool, and then the amino acids are transported to the stomach to synthesize digestive enzymes again. So eating digestive enzymes is not conducive to digestion, because it will be broken down in the digestive system. Because enzyme, as an enzyme, is also decomposed into amino acids in the digestive system and absorbed by the human body, it is impossible to directly act on fat. Therefore, even if the enzyme does have the function of decomposing fat when it comes into direct contact with fat, in the body, the enzyme will not come into direct contact with fat anyway, so naturally it will not have any magical effect.
As for the homemade fermentation enzyme, it may be because there is a word "enzyme" in the Chinese name, and it is mistakenly believed that this thing needs fermentation. In fact, an enzyme is an enzyme and does not need to be prepared by fermentation. What is obtained by fermentation is at best similar to the effect of yogurt, and it may not be able to lose weight and cure all diseases.
Therefore, in any case, enzymes will not make any sense to lose weight, and there is no other magical effect.
