15% of the body weight is made up of the bones that make up the human skeleton. So, a 200-pound person has around 30 pounds of bone weight.
Weight reduction can result in bone loss because there is a direct correlation between bone weight and body weight. The likelihood of bone loss when a person loses weight depends on their starting weight. Bones are significantly impacted if weight loss through dieting results in a decrease in calcium intake or absorption efficiency.
The Huffington Post advises limiting intake of caffeinated foods or beverages in order to prevent bone health when reducing weight, as well as sun exposure or other sources of vitamin D, which aids calcium absorption.
