Have you ever tried medical therapy for your fight against Obesity? Have you ever had surgery for your fight against Obesity? If you answered yes to either of the two questions, then you will be very interested in the study results found by Dr. Juan P. Valderas and his colleagues published in the Journal of Clinical Endocrinology and Metabolism. They found that gastric surgery increases peptide YY (which controls appetite in the gut) and reduces hunger and appetite, while medical therapy has no change on peptide YY, hunger, or appetite. These findings occurred in study participants after they achieved the same amount of weight loss two months after their method of treatment. This explains the difference in success of medical therapy versus surgical therapy in the fight against obesity!
