Pop a piece of gum. Researchers recently discovered that chewing sugar-free gum all day increases your metabolic rate by about 20%. That could burn off more than 10 pounds a year.

Supersize your H2O. Buy the big bottle when it comes to good-for-you stuff such as water.

Buy small. The bigger the package, the more you're likely to eat -- up to 44% more, according to one study.

Spray -- don't drizzle. Use an olive oil sprayer to add flavor to salads, chicken, fish, or pasta, without all the calories. A 2-second spray evenly distributes about 1/2 teaspoon of oil, compared to the 2 or 3 teaspoons you might get when pouring. That'll save you up to 100 calories per use.

Log your food. Writing down what you eat can help you stay in control because you're more accountable. No need to record it perfectly or review what you wrote: The benefit is in the writing itself

Blot the fat. You can dab off about a teaspoon of oil -- or 40 calories and 4.5 grams of fat -- from two slices of pizza.

Pick up the cordless. Burn calories while you talk: Do the laundry (68 calories), set the table (85 calories) or water plants (102 calories). (Values based on a 150-pound person and half an hour of activity.) Not only will you burn calories but you get some work done too.
 

Take a whiff. When you really want those fresh-baked cookies, try this: Indulge in the smell for 30 seconds. Then place a small piece on the tip of your tongue for another 30 seconds. Savoring the smell and taste can help you stop at just one cookie.

Drop and do 10. Before you pry open that tub of ice cream, do 10 sit-ups or pushups. Doing something physical can put you back in touch with your body and your goals.

Mix a juice spritzer. Combine your favorite juice (half of your usual amount) with plain or sparkling water. You can cut up to 85 calories per glass -- and lose 5 pounds or more per year.
