Hi - well it's only day 1 on CS for me, so can't really comment from experience, however, I did do 12 weeks of LL foundation last summer with no lapses and lost close to 4 stone in that time. I didn't do development or route to management, I simply followed a healthy eating routine after our family holiday, until I hit December and put on around 10lbs! When I finished LL I did still had around a stone or so to lose to get to my goal of 25bmi, so now I've got around 2 stone to lose on CS.
I found LL easy and hard, I did get hungry (I think this happens on EVERY diet), so I'm prepared for days on CS where I'm hungry but at least with CS you can have a meal and snacks to curb the hunger pangs - I hope!
I firmly believe that if your mind is set and you're in the "zone" any and all diets will work - but if you're not, you've no hope of success - been there done that many, many times. I know I'm in the "zone" just now and totally focused on my CS journey ahead - so here goes!
