I think with a lot of these health trends, it doesn't take account for the fact that humans are animals.
Animals can't always guarantee they'll get enough water, or enough food, or the right kinds of food. Bodies aren't like a machine that requires specifically calibrated amounts of inputs. Instead if you drink too much you'll pee out more. If you drink too little your pee will be more concentrated so your body retains more liquid. If you get more nutrients than you need, the extra will be eliminated.
It's probably true that with many things (except calories) it's better to get a bit too much rather than too little. Maybe it's true that for water it's better to get nearly the maximum rather than slightly more than the midpoint amount. But, it seems unlikely to me.
This has always interested me, especially when I've read here and there that issues such as obesity is much more accurate as being a diet problem rather than an exercise problem. Not that the latter doesn't help at all, certainly.
Yeah it's a lot easier to eat less calories than it is to burn off that many. 100 calories is like a bag of crisps or so (depends on what) but 100 calories is also about 10 minutes of running which is a lot more work than just eating less. Not that you shouldn't run but if you're trying to lose weight it has a much bigger impact to stay at a calorie deficit.
