I'm not sure I follow you here. Aside from a medical condition you're not gonna accumulate water. And I'm not sure " breath less" would be a popular or effective diet technique. Yes, your body needs water and oxygen as part of using food, and turning into muscle or fat, but it's the food that does all the damage. A very brief evidence of this fact are those that exercise all the time (hence have both elevated breathing and water intake, and yet don't gain weight.) Regarding the tree, you're absolutely right. If only you were a tree that would be a useful comment. Unfortunatly the metabolic process of a tree (all plants) is different to that of an animal. A plant requires water, carbon dioxide and sunlight. Throght the process of photo-synthesis (which only plants can do) carbon is removed from the atmosphere using sunlight as the primary fuel. So, if you like a plant "breaths" sunlight, "eats" air and defecates oxygen.
