Your diet that you posted requires a 500 calorie per day limit. I agree that bodies do go into starvation mode but only in very certain situations and only if those situations have lasted for certain periods of time. I believe the starvation mode excuse is way overused these days!!!!
However, if you limit me to 500 calories per day and put me on an island for two months, when you come back, I will not be overweight :-) ...and I didn’t even need your HCG drops..
the “rotation diet” from years back was based on the premise that you could cut calories drastically for a few days....3 days IIRC....increase calories a bit for the next few days...and then continue on like that...your body won’t react to “starvation” if you feed it near normally periodically..
