First of all, the main component of protein is amino acid protein, which cannot be converted into fat! The protein content of protein powder is generally more than 70%, and its carbohydrate and calorie are extremely low, which can be basically ignored!
Another reason for recommending protein powder to lose weight is that the digestion process of protein powder is complicated, and you will feel full after using it, which is a very safe and effective way to control your appetite.
Finally, I need to add my friends upstairs. Losing weight does not mean that you must go on a diet, but that you need to control your calorie intake reasonably, pay attention to aerobic exercise and eat less and more low-calorie foods. This is the most reasonable way to lose weight.
