Sensitive topic-- unhealthy weight gain

[sushiritto]

Because of this additional stress, extra weight, even from fat, may reduce the risk of osteoporosis, even though extra fat may increase other medical risks.

Not according to the NIH:

Excess body weight due to obesity has traditionally been considered to have a positive effect on bone; however, more recent findings suggest that bone quality is compromised.

Personally, I’d rather eat/take more Vitamin D and calcium and exercise more and lose the weight.
