Hi Lisa, just to let you know i have been doing 790 for 5 weeks and have lost 22lbs !! so definately doing just as well as some on ss. I feel fantastic, and have something to look forward to in the evening with family albeit a small meal I love it!! i did LL 1st for 2 weeks but changed to cd because i wanted to have SOME food.It is still a vlcd ,most cdc's say their clients lose about the same on both programmes. Oh and i have been in ketosis all the time. I cant shout loud enough about the 790 plan. BTW i have altogether lost 1st in 2 wks on LL then 1st 8lbs in 5 weeks on cd 790 ! not bad eh ?2 1/2 stone in 7 weeks altogether!! Rather be doing 790 than giving up completely cos i want a little food!! Good luck in making your decision ,hope this is some help!! Sarahxx
