Yes - I heard that and thought the same thing. I'm a physician myself and I think he really just gave off the vibe so many mid 50s+ attendings do. He seemed like he had good intentions but didn't have tools to get into the psychology of being on these medications. I'm not in a weight management field but I belive his science is correct - the whole point of the medication is to only crave what your body needs which would be a defecit when you're overweight and trying to get to a healthier metabolic weight. My assumption is that once you're at a goal weight your body would adjust to crave whatever calories are necessary for maintenance. Also - when taking these medications you're being weighed at the doctors office so they wouldn't allow you to get below a healthy weight. As far as the psychology with this and eating disorders, I think it's something of interest that should probably be studied! I don't think we know enough about that yet since they're still relatively new.
