I tried Weight Watchers before finding Slimming World and in my first month with WW I don't think I lost more than 3lb. When I calculated my homecooked meals on WW, I was finding I was hitting 20-25 potions for a homemade spag made with extra lean meat on Slimming World, that same recipe - which is my luxury wine edition spag is 1.5 syns and comes with about 1/3 superfree's from the onion, garlic, pepper, mushroom and celery not to mention just about everything else I cook in slimming world easily being no syns with just a little bit of change.
Slimming World have been a revelation in comparison - I've lost 1st3.5lb since I start just over a month ago, I was Slimmer of the Week last week as well as being Slimmer of the Month and getting my first stone of loss. it's been amazing.
