Do I have to follow a special diet while taking the HCG drops?

Yes! The HCG protocol is very precise and the guidelines must be followed exactly or one cannot expect results. It is the combination of the HCG drops and the HCG diet guidelines that produces results – simply taking HCG drops alone is not effective for weight loss.  

Think of the protocol as a treatment or a prescription, not as a diet. On regular diets, you can cheat without making much of a difference. On the HCG protocol, cheating even once means you have stopped the treatment and you run the very real risk of stalling for several days or gaining. You can recover from that, but you lose more ground than you would on a diet.
