Basic Biology: The human body can not directly absorb protein, but can only absorb amino acids to synthesize protein.
When you eat food and drink enzymes, enzymes break down the protein of food (not its own protein) into amino acids in your stomach, which is more conducive to the body's absorption of nutrients. When you synthesize protein, your weight will be heavier.
Why do some people say that they lose weight after drinking enzymes? Because he went on a diet and even did a lot of exercise. It's strange not to lose weight.
