Yo-yo no more.
Even though thin women are generally more susceptible to osteoporosis than overweight women, women who are chronic dieters may also be at increased risk of weak bones regardless of how much they weigh. Studies suggest that years of dieting may have a cumulative negative effect on bone health: Some women eat so poorly that they haven't taken in the nutrients needed to build or maintain their bone strength. Dieting by severely restricting food intake is never a good idea. (If you want a better way to lose weight and keep it off for good, feel free to check out my Online Weight-Loss Program.)
