Creatine does not appear to make you gain weight, although some people may notice a slight increase in weight after starting this supplement. This usually happens because creatine can increase water retention in the muscles, especially during the first few weeks.
Over time, creatine may also increase muscle mass. However, it does not seem to significantly increase body fat and, in some people, may be linked to a small reduction in fat.
Before starting creatine supplementation, consult a doctor or registered dietitian to ensure it is used safely and effectively. For weight loss, it is also important maintain a healthy, well-balanced diet combined with regular physical exercise.
