Interesting!

Very interesting.

I learned in my nutrition class that fat cells shrink when you lose weight they don't go away. Fat cells don't like to be starved so when you lose weight, a hormone in the fat cells (could be leptin, I forgot) sends signals to the brain to eat more! Your appetite increases. This is why its especially hard for those who have been overweight as a child into adulthood to lose the weight and keep it off. Its scary! Good article. Thanks!

This reaffirms my decision to get the sleeve and helps to explain why have always yo yo'd.
