I have been doing Optifast for about two months.
I lost 3 kilo in the first week.
I then got a bit naughty and put on a kilo or three and since then have been better.
All up I have lost about 5 kilo.
I feel great, get a little bit hungry sometimes, but when that kicks in I drink lots of water (about 3-4 litres per day) and I try and do at between 30 - 90 minutes walking per day.
I must say I dont stick to the whole thing religiously as I believe in moderation with everything and I do love my glass of wine at the end of a day!
I feel toned, aside from my fat belly which I believe will only ever go away with surgery! Bring on my 40th birthday as I have begged my husband to buy me a tummy tuck as a gift!
I am interested to hear if any other slimmers have used this, and what success did you have.
