Post Menopausal Women Who Lose Weight May Also Lose Bone

In a recent study, it was determined that post menopausal women who successfully lose weight also seemed to lose bone density in the process.

In this study, 343 women were randomly assigned to a low-fat diet along with an exercise program while the other half just maintained their normal lifestyle. In the study, the women on the diet and exercise lost modest amounts of weight while the control group put on some pounds. When bone densities were performed, it was noted that the women who lost the weight also had lower hip bone densities. (Journal of Clinical Endocrinology and Metabolism. October 2007)

In my opinion, this study does not suggest that losing weight increases the risk of bone loss. Instead, this study suggests that women who go on a low-fat diet with a little bit of aerobic exercise will end up with some bone loss. This is not an ideal way to lose weight, especially because the studies have demonstrated the importance of healthy fats in the proper growth of bone.

We also know that people who eat a low-fat diet also have a tendency to increase their carbohydrates which can promote bone loss. Mild to moderate aerobic activity does little to improve bone density, especially in the presence of malnutrition, which we often call by a different name…dieting.

If you want to lose weight, or more accurately lose fat, then focus you diet on eating low-carb, real foods, full of protein, fiber, and healthy fat. While pursing a healthier diet, supplement with extra calcium, magnesium, vitamin D, fish oil and other nutrients known to support bone health.
