I have read a lot on the net lately about the evils of 1200cal diets. I won't go in to my philosophy (you know it well ) but the forums/blogs I read are full of people whose metabolisms have been screwed by 1200cal plans. They might work in the short term for some, but they really do destroy your body so when you're an old chook like me, you start reaping with whirlwind

Good luck Ill be watching with interest
