Hello! I used Herbalife after my 3rd son and easily got back into my size 3's I hadn't worn since I was 22. However , just like with any weight loss program you have to stay on it for maintaining that weight loss. So, my advice is do something that you can live with for the long run whether it is weight watchers, Herbalife, Slim Fast, diet and exercise, etc.
The one kudo I will give to Herbalife is it was super easy to follow, there is a lot of support if you have the right distributor, I felt great and had a lot of energy on it, and it really targeted my belly fat which is always difficult to lose after you have children! I am now pregnant with my 4th child and I will use it again to lose and maintain my weight if that is any reference for you.
Whatever you choose, good luck!!
