HCG Hormone Diet on Newsfeed -Trying to lose weight? Well, don’t worry there’s a new diet that you can not stick to! It’s the HCG diet. HCG is a substance produced by women when they are pregnant to help turn fat from problem areas, into food for the growing baby. It’s also what home pregnancy tests look for in urine to see if you’re knocked up. Now the HCG diet isn’t going to have you drinking some girl’s pee, it consists of getting daily injections of the hormone for 23 to 40 days and only eating 500 calories a day. Wow, only 500 calories a day? I think I’d be so hungry I’d want to drink that girl’s pee.
