i did it. i love weight. i freaking hated it. i was so hungry that i felt faint on more than one occasion. the foods for my "shape" were mostly foods i would never ever eat or didn't have a clue how to prepare. there was a limit to how many times i could eat 1/8 of a can of tuna fish on a freaking lettuce leaf.
We returned ours and got our money back before the 6 weeks was up.However, my hubby had a better body type and his food was manageable. He didn't hate it nearly as much as i did. i lost about 20 lbs, he lost about 35 and we both gained it all back almost immediately.
Seems like a crash diet and something most people would not want to continue doing over a long period of time. However - i have heard there have been changes and it was about 6 years ago that I tried this plan.
