Diets that didn't work

[Skandi]

Has anyone tried a diet, whether it was a "fad" diet or otherwise that really didn't work, could you tell us what it was and why you think it didn't work? That way we can hopefully avoid it!

I have only considered such things I was looking at the GI diet I have one of the books but I stopped reading at the point where it was recommending artificial sweeteners and low fat margarine.

The Lemon Detox Diet.

It made me crave fatty foods, feel weak and unenergetic. After coming off the diet I was about 4kg lighter and physically looked skinnier but it only lasted a week until I'd put it back on and it didn't help my eating habits at all.
