The human body is constantly trying to maintain a static temperature of 98.6 degrees. The colder the surrounding or internal conditions, the more calories the body burns to keep warm . Metabolism acts like a furnace that must burn fuel to keep the body nice and toasty. Luckily, the body’s fuel of choice for keeping warm is “brown fat,” more commonly known as the stuff comprising muffin tops (and not the tasty kind).
Drinking iced water is one of several ways to harness this mechanism for weight loss, since the body must compensate for the sudden temperature drop. One 16 ounce glass of cold water can burn up to 17.5 calories, no treadmill required. Cold showers, a lowered thermostat, and vigorous swims in pools full of orange juice concentrate all utilize this same mechanism. But don’t run off with the penguins just yet: exposure to extreme cold might do a lot more harm than good and can cause severe complications in people with cardiovascular conditions. Plus, fewer than 20 calories per glass will hardly transform modern-day Val Kilmer back into Iceman.
Still looking to melt off extra pounds (or at least ounces)? For that thermodynamic edge, throw some ice in a drink and get ready to harness that inner, slimmer cool cat.The Tip
Drink ice water to speed metabolism and rev up weight loss (a little, at least).
