More water is the starting place for virtually all health concerns, weight loss included. For one thing, drinking more water keeps you feeling full with less food. But even better, chugging water has been found to increase the number of calories burned for an entire hour after you drink it.
Cold water especially seems to spur a 25% increase in resting body expenditure, or calories burned while doing nothing. In fact, boosting your daily water consumption over 1 liter could net you an extra 4.4 pounds of weight lost over a year’s time.
