There has been quite a bit of research done regarding the issue of bone loss as it relates to weight loss.  As I was researching this article I saw that Science Daily had wrote up a great article on this subject with clinical research, and here is what they said, “A higher-protein diet that emphasizes lean meats and low-fat dairy foods as sources of protein and calcium can mean weight loss without bone loss–and the evidence is in bone scans taken throughout a new University of Illinois study.”

The research, which compared the results of a high-protein, dairy-intensive diet with a conventional weight-loss diet based on the food-guide pyramid, was published in this month’s Journal of Nutrition.

“This is an important finding because many people, especially women in mid-life, are concerned with both obesity and osteoporosis,” said Ellen Evans, a U of I associate professor of kinesiology and community health and member of the U of I Division of Nutritional Sciences.

“Furthermore, treating obesity often increases risk for osteoporosis. Many people lose bone mass when they lose weight,” she said.
