Five Star WonderSlim Review

Delicious & Effective

I was previously on (Other Brand). But kept reading how Wonderslim is less expensive, tastes better and is just as effective, so I tried it. ALL TRUE!! Love it! I would highly recommend. Especially now that (Other Brand) discontinued their discount program. Another plus with Wonderslim is that you don't need to keep your credit card on file for automatic delivery--You order when you want to. The minimum for free shipping is also much, much less than (Other Brand).

Five Star WonderSlim Review

WonderSlim lives up to its name! Wonderful!

I have tried MANY prepackaged plans before (Other Brands) and I have to say that Wonderslim is by far my favorite program ever!

Although everyone will have favorite and not-so-favorite foods, I find that I have MANY more favorites in this package than ever before! The shakes are actually really good! They totally curb any sweets cravings I may have (especially during my ToM).

The spicy cheese and pasta, chocolate cake, caramel and lemon puddings, hot cocoa and berry blast drinks are among many of the products that make it so easy for me to keep on track!

I try to maintain 100 or less carbohydrates a day (by tracking my progress with FitDay), I go along with the plan and add the meal that is suggested and a fruit based on what products I have chosen from the Wonderslim program for the day!

I always call in to make my orders and everyone is exceptionally friendly and ready to help and customize your order! Thanks for the amazing customer service and the fabulous, TASTY products that help us learn how to live a new lifestyle!

Five Star WonderSlim Review

OMG! Loved it all!

I'm a former (Other Brand) customer. I ordered their 4wk package and realized I only liked shakes and bars. With Wonderslim, I LOVED IT ALL! I ordered it on Friday and it was at my post office on Monday! The shakes/puddings/smoothies mix very well. Sloppy Joe and mac n cheese was delish! Cheesecake tastes sinful! I'm losing weight and it tastes great!
