Years ago, a friend said, "They can take away my health insurance because I smoke and have HIV on the same day they take away health insurance from the fat-assed Americans who eat themselves to death."

In Study, Hormone Reduced Appetite in Mice
Hungry or full, fat or thin: it is mostly a matter of hormones, dozens of them, carrying messages between the digestive tract, the fat cells and the brain. Eat. Don't eat. Burn calories. Store fat.
