I did a quick search and cannot find any studies supporting high fat

diets increasing bone mass. I really want to find evidence supporting

this but everything I see supports the opposite.

I didn't get to read all the articles so forgive me if I missed the

goods ones. I wonder if it has something to do with the type of fat

they are feeding the rats. Are they giving them hydrogenated fats?

Abstract:

Abstract. Diets with a high saturated fat content can produce

deleterious effects on the absorption of dietary calcium and

consequently an adverse effect on bone mineralization in growing

animals. Hence dietary fat may have long-term consequences for skeletal

health and skeletal pathologies such as osteoporosis.
