Things You Didn't Know About Your Body

Guzzle -- don't sip -- water: Downing big gulps cues your body to get it into the system faster.
To lose weight, drink cold water. Your body has to expend extra calories to heat up the H2O in your stomach, resulting in a rise in your resting metabolic rate. In fact, in a 2003 German study researchers estimated that drinking two additional icy quarts a day would help you burn about 100 extra calories -- or the equivalent of a pound of fat every five weeks -- with no other changes in exercise or diet.
So that's why we like sushi. By simultaneously eating "bad" high-glycemic foods (pasta, rice, etc.) and protein (fish, meat, etc.), you greatly lower the former's absorption rate -- and reduce their tendency to be stored in the body as fat.
Eat cheap tuna. More expensive canned albacore "white" tuna has been found to contain as much as three times the mercury of canned "light" tuna.
Why settle for some overprocessed vending machine offering when you can have a second lunch? A whole-wheat PB&J sandwich at 3 pm will keep your energy up until dinner, help your heart with a megadose of monounsaturated fats, and has fewer calories than cheesy peanut butter crackers.
