To my mind you definitely have a place in 3FC. As others have said, many of us may be striving for something that looks similar to IE, even if we call it a diet.
If I believed for one minute that IE would work for me (i.e., allow me to live in weight equilibrium), I'd do it in a heartbeat. I simply don't trust my appetite as a guide. After all, I'm the person who ate a whole box of chocolates at age 4 without feeling any ill effects.
I still find your posts and approach inspiring and instructive. Don't leave!
