Fidget. Studies show that lean people fidget for about 150 minutes a day more than obese people do. That kind of low-grade activity (tapping feet and fingers, twirling hair, gesturing while speaking, etc.) can burn 350 calories a day, which translates into 10-30 pounds a year! It’s called Non-Exercise Activity Thermogenesis (NEAT), which is basically any movement that isn’t intended as exercise. You can burn an extra 100-150 calories an hour by increasing NEAT. Here are some ideas:
Reach for the caffeine, pass on the sugar and cream. Caffeine tends to increase the number of calories you burn, probably because they stimulate thermogenesis — one way your body generates heat and energy from digesting food and because the boost in energy means you move around more (which means more calories burned). Having 250 milligrams of caffeine with a meal can increase the calories spent metabolizing the meal by 10%. Green tea, in particular, seems to be especially conducive to burning calories.
So instead of having soda or any other calorie-laden drink with your meals, go for an unsweetened cup of coffee or tea. Skip the sugar, milk, cream, or any other caloric enhancements so that you don’t replace the extra calories you’re burning. Drinking coffee or tea plain will take some getting used to, but purchasing high-quality beans or tea leaves will certainly help.
Drink lemon juice in lukewarm water. This formulation gets more effective when done on an empty stomach.
Drink ice water. The colder the water you drink, the more calories you burn, since your body expends more energy warming up the water. If you have 8 glasses (64 oz) of ice-cold water in a day, you’ll burn 70 more calories than if you drank 8 glasses of a body temperature beverage. In fact, this principle will work with any calorie-free beverage, as long as it’s ice cold, so you might want to ice up that coffee and tea mentioned earlier for cumulative calorie-burning effects. Keep in mind, however, that the weight loss impact of this one particular practice isn’t drastic: It would take 435 glasses of ice water (about two months, assuming 8 glasses a day) to lose one pound. And, don’t go overboard. There’s such a thing as water toxicity. Follow the guidelines in How to Drink More Water Every Day.
Chill out. Shivering burns calories, so if you can spend more time outside when it’s cold, you’ll crank up the calorie furnace. Even if you don’t shiver, though, you can get a 3-7% increase in calorie burn just from your body warming itself (similar to the principle at work when you drink ice water). Just don’t run away with this idea and get yourself sick!
