Science says your bones are NOT bigger. "[A] study revealed that adults with excess fat in their blood and organs are more at risk from osteo-porosis, which causes bones to become progressively weaker and prone to fractures.  The researchers think that instead of protecting bones, the extra fat triggers the formation of cells called osteoclasts, which gradually wear them down. They also suspect that if large amounts of fat are stored within the bone marrow, it inhibits the production of new bone tissue." Science for the lard-asses.
