Just drink two tablespoons of extra-light olive oil early in the morning... don't eat anything else for at least an hour afterward... and in a few days it will no longer take willpower to eat less; you'll feel so full all the time, you'll have to remind yourself to eat.

...and then increase the dose to 4 tablespoons if that doesn't work, and then try some other stuff such as crazy-spicing your food if that doesn't work, according to page 62 and Chapter 6 of Roberts' "Shangri-La" Diet" book. I hope you at least tried the higher dose before giving up.
