There are lots of claims that HCG, a pregnancy hormone, works great for loosing weight. I'm here to tell you that if you really want to loose this is not the way to go. HCG diets do work, at first, because along with the hormone they have you reduce your daily calorie intake to a ridiculously low number. Of course when you starve yourself you are going to loose weight and the minute you quit doing so it is going to come right back. If you're going to try to loose weight in the new year, I know I am, make sure you do it in a healthy way so your body can feel the joy of your weight loss instead of eating itself to survive!
