Obesity is a mental disease, rather than a physical one. The hormonal pathways in your body fail to function properly, causing you to not feel satisfaction from eating food and causing overindulgence. Bariatric surgery causes weight loss by not only physically downsizing the stomach, but hereby also severely decreasing ghrelin production (hunger hormone). That caused me to think; why are there no medicine targeting the receptors of ghrelin and/or leptin? We treat depressed people with medication altering the uptake of mental hormones. Why not do the same with appetite hormones?

This also account much better for differences in body weight and the difference in difficulty between people to maintain a healthy weight
