How does the HCG Protocol work?
You begin with 2 load days (48 hours). It will take up to 72 hours for the HCG to be in full force in your system. This is why you can load for 48 hours. By the time the HCG is at full force you must be eating 500 calories from the list of approved foods. Dr. Simeons gives a two meal eating schedule that may be used as a guide. He clearly states in the manuscript that the user may eat smaller, more frequent meals if desired as long as all of the food is eaten and no food group is intentionally missed.
