Sports coffee mainly provides energy through the stimulation of caffeine and enhances the metabolism of the body. In the case of moderate intake, sports coffee will not directly lead to weight gain. However, if you consume a lot of sugar or high-calorie food while drinking sports coffee, and you don't consume these extra calories through proper exercise, it may lead to weight gain.
In addition, caffeine has diuretic effect, which may lead to dehydration of the body. Long-term dehydration may affect metabolism and body function, thus leading to long-term weight gain.
In short, moderate drinking of sports coffee will not directly lead to weight gain. However, if you want to control your weight, it is recommended to achieve the best results through reasonable diet and moderate exercise. If you are worried that your personal situation can't control the intake of sports coffee, please consult a professional doctor or dietitian.
