The magic of the HCG Diet is not Human Chorionic Gonadotropin. HCG is a placebo injection. Google the American Society of Bariatric Physician’s position paper on HCG. The magic of HCG is the 500-650 calorie Simeon’s Diet. Going to a physician’s office 7 days a week for HCG injections, reinforces weight loss by keeping you focused enough to follow a 650 calorie diet. HCG injections do nothing to help you lose weight. The injection I use for weight loss is GLP1. The injection is 97% pure GLP1, so it’s almost not a drug. GLP1 (Glucagon Like Peptide 1) is one of the 4 hormones that control body weight. The more GLP1 you have on board, the less fat storage and the lower your appetite. The other 3 hormones that control body weight are insulin, ghrelin and leptin.
