Very different things true - but not mutually exclusive. I WAS on subQ HCG as part of hormone replacement therapy which included testosterone cream (prescribed by a doctor, compounded at a local pharm, and paid for by insurance if anyone doubts the authenticity) but am now taking it "off label" and in different doses/ways for weight-loss purposes (again doctor, pharm and health reimbursement account). HCG will not make you lose weight but HCG allows me to feel great while on a greatly reduced calorie diet. I'm coming up on 2 weeks and feel great, have great energy, have quit blood pressure meds as well as reflux meds and have zero hunger. My bodyfat percentage is decreasing (based on my ironman scale) and I'm eating more green veggies than most others on here. In short - its working for me and is a great way to jumpstart/restart dietary changes.
I guess it would just be easier to eat less and exercise more, but for SOME of us its like telling a bald guy to just grow hair, or a short guy to just get taller.
