A bit tangential but..
A couple of years ago, I researched and wrote up an article on the effects of drinking additional water and weight loss. I was just curious because I was dieting and consistently read advice to drink lots of water to help aid dieting.
tldr: "thermogenic" (calorie-burning) effects of additional water intake are mostly negligible and based on old, non-replicated research. There may be very modest benefits for obese people during dieting, but the research is unclear. No other clear benefits that have a solid backing of research (that I could find).
