Obesity is so much more than eating too much. Body type, medication, hormonal changes, physiological problems ,one pill could never solve this complex issue. Most of us know someone who seems to eat what they like do very little exercise yet remain fairly slim -this does not mean they are healthy as they could be laying down fat internally which is not seen. Others will do moderate exercise have quite a healthy diet but will always be a bit n the chunky side -you can't make a cart horse into a thorobred by starving it! Education and cheaper 'healthy' foods would be a start but if there ever was a pill someone would make a fortune.
