Why so over hungry?

  Do you ever feel like you can't stop eating? Like without food your life wouldn't be complete and you just NEED food!? I think everyone has, and this week I read a post about eating and obesity. People find it hard to limit fats, too much fats or too less can make you die thought, well then why does our body do this to us? Scientists have been experimenting on rats to see how their molecules react to sugar and fats. Why would scientist do something like this, you might be wondering. They do this so they can figure out some sort of drug that when ever we eat fats they wont send any messages to our brain as in if our brain wants more. While preforming the studies, it came out that endocannabinoids molecules that help the brain when it is time to eat are the molecules that make the brain want to eat more or not eat at all.
“It was a very striking effect,” Daniele Piomelli told Science News

The scientists working on this project compared the molecules with other body systems and how they interact. Thing brought up were: THS, the molecule in marijuana. This molecule activates the endocannabinoids, this is why people who smoke are most likely to feel the need to smoke.
  "For the new study, the researchers divided rats into four groups and fed each group a different diet. Three of the diets were rich in a particular nutrient. One group gobbled corn oil, a kind of fat. Another group ate a sugar-rich diet. A third group devoured a protein-heavy diet (protein found in meats, nuts and dairy products helps rebuild damaged cells in the body). The fourth group received a well-balanced diet."
 Observing all the results and rats, the scientist found out that the system was mostly activated in the high-fat diet. The reason for this study was to help overweight people loose some weight. Now people are working on making these drugs so life can be easier.
  In my perspective I found this topic interesting because I have read something like this before but it had a whole different idea behind it. I am curious to see if the drugs will actually work and how many people will believe in them and buy them. I choose this topic because I thought a lot of people now a days have problems with eating and staying fit and I thought you would like to find out why it is so. I hope the study will continue in a good way and soon people will be living a happier life in their body.
