Thank you Sajehill for writing what I have been thinking as well. This is not a fad diet or a way to drop a lot of pounds for a special occasion. It is a protocol for people that really want to change their life. For me the pounds and inches lost is a great thing but my real holy grail is stabilizing my metabolism. I have followed pounds and inches and dedicated myself to this protocol so I can reset my metabolism for a lifetime of healthy eating. P3 for 3 weeks to stabilize by adding more foods with the exception of starch and sugar. P4 is a minimum of 3 weeks to start adding back in starches very slowly so you can figure out which foods trigger a gain for YOU and avoid those foods for the rest of your life. Or eat them in moderation. Dr. Simeon never says add back in sugars, he says slowly add back in starches. Here is an exact excerpt from Pounds & Inches:
For the following 3 weeks all foods allowed except starch and sugar in any form (careful with very sweet fruit).
After 3 weeks very gradually add starch in small quantities, always controlled by morning weighing.
The three weeks of P4 rule comes in because he states that you need to take 6 weeks off between rounds. However if you have done your final round or don't plan to do another round for a longer period of time then P4 becomes your lifetime maintenance.
Your analogy of an alcoholic is dead on for me. I noticed while loading for this round that once I started eating carbs and sugar combined it set off an addiction that made me crave more. I wasn't hungry but wanted more. Consequently I gained 7.2 pounds on my load days this round. That was an eye opener for me to be very diligent in my P3 and P4 efforts after this round.
I think a lot of people are going to clinics or buying HHCG or HCG off the internet and not understanding the original protocol. So they are treating this weight loss plan like all others that they have failed at. Everyone needs to read Pounds & Inches and really understand the protocol before ingesting any HCG.
