Hunger

How many rolls, cookies or baby carrots would you have to eat to feel full. It's probably more than you'd want to admit . It may not even be possible with carrots. But what if you ate that volume of filet mignon? Hunger and fullness are controlled by hormones that send messages between your gut and your head. And different foods send different messages. Some say eat more and others warn you to slow down. Now a study finds that protein is, indeed, key in generating signals of fullness. The work is in the journal Cell.
