Trimming some fat may eliminate some guilt, but be warned: Buying foods labeled “low-fat,” “non-fat,” or “fat-free” may encourage you to eat up to 50 percent more calories, according to three studies by Cornell University’s Food and Brand Lab. Fat’s not the issue when it comes your weight since most of these foods only have about 15 percent fewer calories than their regular counterparts. Go for the full-fat version and eat less—you probably will naturally since they taste better.

In addition to diet, exercise and other lifestyle factors can also play an important role in bone health. Smoking and drinking too much alcohol can increase your chances of developing osteoporosis, while weight-bearing exercise (such as walking, dancing, yoga, or lifting weights) can lower your risk. Strength or resistance training—using machines, free weights, elastic bands, or your own body weight—can be especially effective in helping to prevent loss of bone mass as you age.
