I LOVE weight watchers! Its the best weight loss program I have ever done, to date. Not only does it help you lose weight but it teaches you the tools and knowledge you need to be able to continue to make wise food and exercise choices for the rest of your life.
I also know that Weight Watchers takes in to account breastfeeding which i think is brilliant for those mums who are nursing but would like to drop those few extra KGs that they accumulated during pregnancy. I havent personally breastfed while doing WW but I have friends who have and they had great success.
I love the online feature as I found loads of great recipies, and preferred to do my tracking online rather than paper.
Overall I lost 17 kg with WW and did not find it that expensive to do the meetings.
