Losing weight fast is a bad idea. It's very stressfull on the body and psyche and most importantly it's ineffective and unhealthy.

Your body fat acts like a storage for water insoluble toxins, such as the xenoestrogens mentioned above, which get liberated and reach high levels in the blood stream when you quickly lose a lot of fat.

Also, dropping pounds fast can cause stretch marks as your tissue cannot adapt that fast. Doesn't look very attractive, imho.

I don't believe in crash diets or diets at all as you have to lose weight and then maintain it...you need to think long term.
