Eating creatine will not make you fat. When you first start using creatine, you will obviously feel that your muscles are getting bigger and stronger. This is because creatine can make muscle cells of human body store a lot of water; When all muscle cells absorb more water and increase their volume, muscles will naturally become fuller and more tangible. Stop using creatine and lose weight naturally. Cell expansion and obesity are two concepts.
But eating creatine should be combined with carbohydrate intake. A lot of carbohydrates are bound to make you gain more fat while gaining muscle. There is no way.
Fat loss and muscle gain cannot be perfect at the same time, only depending on your focus.
