No, taking the HCG drops are not advisable as they are hormones used for other medical conditions not weight loss. The diet does cause weight loss but also gallstones and blood clots. Your problem is you have dropped your basal metabolic rate to a point you are too fatigued to do anything to get it back up and you can t lose weight because you cannot create an energy deficit. That is what is causing your exhaustion and difficulty exercising. You have little glycogen and what you do have is used up quickly when you attempt to exert yourself. To raise your metabolism begin by drinking green tea three times a day; start with low carbohydrate or you will gain water weight and focus on slowing increasing carbohydrate and emphasize low fat protein sources and good fats like cooking with canola oil, using virgin olive oil, nuts, etc. As The green tea will increase your metabolism as will caffeine. Once it starts going up you can add a little more carbohydrate. If you need more guidance, feel free to come back to HCM. Kathy Shattler, MS,RDN
