Drink low-fat hi-cal milk

If you drink milk, switch from whole milk to 1 percent fat.

Studies show calcium-rich dairy products can help adjust your body's fat-burning machinery and help you lose weight. But you don't need the extra fat.

If you drink 8 ounces of milk each day, and all you do is switch from whole milk to 1 percent, you'll save enough calories to lose 5 pounds in a year. That's pretty effortless.
