I did it for a month or so to lose a few kgs before we got pregnant early this year. I found it easy apart from the evening meal with DH. Not being allowed anything like potatoes/pasta was hard as we have pasta a couple of times a week as it's quick and easy and DH loooves his potatoes!

But, during the day it was a cinch and the weight just fell off. I lost about 5 kgs in 3 weeks and was wearing my "skinny " clothes that had been sitting in the wardrobe for a while.

Just make sure you excercise and drink the recommended water. Chromium supplement tablets are a good idea too if like me you are addicted to sugar!

Good luck.
