I have been following primal pretty strictly for several weeks now, and I am surprised how i am not overly concerned with my next meal or crazily hungry. I have always been a big eater(volume wise), and I am surprised by how may appetite has been controlled by eating this way. I can go many more hours than usual without food without getting really edgy and hungry. I know some say it is the protein keeping us satieted. I think it might be more the fat and/or the quality of nutrients. I did well losing weight following Body for Life, which is pretty high in protein, but low in fat, but I was always amping for the next meal. I think the lack of fat was causing that. What do you guys think?
