I did this diet about 2 years ago for about 4 weeks but then have up. There was weight loss but until this day I've swore it's the most vile diet ever. Anyway now I'm hypo I'm finishing it quite hard to burn calories so thinking of going back on the lipotrim. However what puts me off is that a 500 calorie meal replacement diet must do some damage to the metabolism so with my body already being out of balance it wouldn't be a good thing, on the other hand I've read some amazing reviews from people with an under active thyroid who have done it. Can anybody shed some light?
