How much do bones weigh?

The bones that make up the human skeleton comprise about 15 percent of the body weight. Thus, a 200-pound person has a bone weight of about 30 pounds.

The direct relationship between body and bone weight means that weight loss can lead to bone loss. The initial body weight determines the risk of bone loss if a person loses weight. If weight loss through dieting involves reduced intake of calcium or efficiency of absorption, bones are substantially affected.

The Huffington Post recommends exposure to sunshine or other sources of vitamin D, which facilitates calcium absorption, and decreased intake of caffeinated foods or drinks to avoid compromising bone health when losing weight.
