I have been using New Lifestyle! They have very good comparable to Optifast and Medifast, there is only one major difference... They actually taste good!! (don't eat the pudding, ugh) Their shakes, bars, soup, hot drinks and snacks/munchies are extremely balanced and did I mention they taste good!!
I don't even get paid to say how good this product is, though I would be rich by now when I think about how many people I've turned on to New Lifestyles! Check them out... I hope they work for you!
