The answer is osteoporosis.
Osteoporosis is a condition characterized by loss of bone tissue, so bones become more fragile. It is the result of deficiency in calcium or D vitamin or of hormonal changes. Human body cannot produce calcium, but 99% of all calcium in the body is in the bones. Also, human skin is able to produce D vitamin in sunlight. Both calcium and D vitamin are necessary for strong bones.
Thus, if a person eats a lot of food that is high in calories and fat and takes daily calcium and vitamin D supplements, this suggests that osteoporosis is diagnosed.
