Grass controls the diet too much and has a rebound. Filamentous birds are better, but they don't seem to be as fast as grass. The way to lose weight varies from person to person. The most effective way for me to lose weight is acupuncture. Anyway, no matter which way you lose weight, you should develop good eating habits. You can't just count on ways to lose weight, you have to do it yourself. After all, there are successes and failures in every way. It's up to you. But you should note that once you choose to lose weight, it will be a lifetime thing, because there is no way to lose weight without rebounding! If you are not too fat, I advise you not to lose weight.
