Hi OP.... For the healthy adult, it does take a considerable amount of water to cause overhydration--"water intoxication"-- there have been documented deaths from water intoxication. (most recently, some hazing deaths at a fraternity that forced pledges to drink excessive amounts of water) That does not mean that you should follow your trainer's advice without consulting your doctor. I would chat with your physician first. Some pre-existing conditions can make excessive water intake more risky, as well as your medication regiment. Prescriptions drugs can definitely impact your urinary output/load on the kidneys. That said, it is important to hydrate when exercising, and the rule most people use is the old "drink til it's clear"--when you're peeing clear, you're adequately hydrated. (just keep drinking if you continue to work out, sweat a lot, esp. in high temperatures or high altitudes.) His other advice--water makes you feel more full is true, and many nutritionists suggest drinking a full glass of water before or with dinner, to prevent over-eating and help you feel full. Your body does expend some energy "heating" the water inside your body--water goes in cold, comes out hot--I would imagine however that the amount of calories it takes to "heat" the water is negligible when it comes to significant weight loss.
