It looks like you're referring to leptin, which is something else entirely from the macronutrient protein, and doesn't work in humans the way it does in rats.

A good primer on leptin is:

yes my comment was about leptin. it is possible that the research done here is producing a result which is different from the study you point to in your post.

i'm not a doctor and don't play one on TV either,so I'll just say that more tomatoes and more chicken, turkey and beef may give me something to lower many of the artificial killers of old people. time will tell. Thanks for your comment.
