Question 4: What is the most dangerous fat on your body?
A) The fat in your thighs
B) The fat in your buttocks
C) The fat in your belly

The correct answer is C.

"The thighs will cost you a few dates, but it's the fat in your belly that we worry about," Dr. Oz says.

When the fat is stored in your stomach, your body has easy access to it, Dr. Oz explains. The fat then creates an inflammatory process that irritates your arteries and puts you at risk for blocked arteries.
