It's not really bone desntity although it could be, for example some people have extremly huge abs while having medium bodyfat, so their stomach sticks out as if they have a fat stomach...your weight distribution is based on the alpha 2 recepotr sites, which your estrogen levels dicatate, basically it's your bodies favorite spot to store fat, for men it's mostly love handles and mid section and chest, for women its lower body...and yes you can spot reduce look into lipoderm-Y at 1fast400.com its a topical fat burner, and someone don't come at me claiming that it only drains that area of water, it doesn't. peace
