I've been hearing just drinking more water can help lose weight?

Can help: Drinking water may not help you burn more calories, but it avoids adding extra calories that have little nutritional value. By drinking water you allow your body to burn more of the calories you obtain from foods rather then having to "waste" the effort burning the calories obtained from soda, ice tea, or some other sweetened drink. So, you need to cut back on the sweetened drinks for it to work.
