5. Trick your metabolism with fat-fighting foods.
I know you've heard it before, but it's true: It's really not just about how much you eat, but how much of which foods. There are plenty of healthy foods you can eat all you want of -- and no, that doesn't mean stuffing your fridge with celery sticks, 1970s-style. Instead, make a few simple tweaks to your diet, incorporating foods that actually fight fat instead of those that trigger it. Then eat other foods in moderation, and you should be OK.
6. Make muscles an ally in your weight-loss campaign.
There's one thing the exercise gurus have gotten right: The more muscle mass you have, the more effectively your metabolism burns calories. But sad to say, a natural tendency of aging is to lose muscle, gradually replacing it with fat. So in order to enlist the calorie-burning abilities of muscle, we do have to work at it.
A common misconception, though, is to mix up muscle-building with aerobic exercise. Both are good, but the aerobic part -- though it does burn calories -- isn't what we're talking about here. What you really need to focus on for long-term benefit is basic strength training. Buy some hand weights, a bar, and some stretch bands, and channel your high school gym teacher. Make it as pleasant as possible; work out while you watch the evening news or your favorite sit-com. Slowly and gradually build up those biceps, abs, deltoids, and glutes, and you'll have some key allies in your fight to prevent age-related weight gain.
