  1. There are particular regions of the brain that regulate hunger, and tell us
  2. when we're hungry, or when we're full. The most important region is the
  3. hypothalamus. In particular, there is one important part. The lower middle of
  4. the hypothalamus controls the sensation of feeling full. So in animal studies,
  5. when they lesion, or cut this part of the hypothalamus, the animal becomes
  6. obese. Because the signal for being full is broken. So the lower-middle portion
  7. of the hypothalamus controls the sensation of feeling full. On the other hand,
  8. the lateral area of the hypothalamus controls the sensation of being hungry.
  9. Again, in animal studies, lesions in this part of the hypothalamus. Leads
  10. animals to become very, very thin, because they don't know they're hungry.
