  • The Malaysian Journal of Medical SciencesAlthough dietary supplements are popular, a lack of regulation and research into these kinds of products’ effectiveness.
  • Journal of ObesityThere is little clinical evidence to support the use of dietary supplements for weight loss.
  • American Family PhysicianAccording to one study, “Because of insufficient or conflicting evidence regarding the efficacy of conjugated linoleic acid, ginseng, glucomannan, green tea, hydroxycitric acid, L-carnitine, psyllium, pyruvate, and St. John’s wort in weight loss, physicians should caution patients about the use of these supplements and closely monitor those who choose to use these products.”

Any WonderSlim Lawsuits?

In 2015, Diet Direct was sued by the Environmental Research Center, Inc. because the company failed to warn consumers about the potential lead content in some of their products. A large variety of WonderSlim shake varieties were named in the suit.

WonderSlim Alternatives

Medifast is a diet that is very popular. It is quite similar to WonderSlim with bars, desserts, shake,s and lite entrees.

The WonderSlim v.s Medifast battle has heated up with recent price drops. They have recently retooled their diet line up to make it affordable by al,l and hence it is no longer more expensive than WonderSlim, either.

There is another diet plan called the Ideal Shape diet which is similar to WonderSlim, althoughit is a bit limited in terms of product options. On the other hand, this diet plan happens to be cheaper than WonderSlim.

The cost range of Ideal Shape ranges from about $2.50 to $4 per day. The shakes are gluten-free and also kosher certified. Ideal Shape shakes contain a unique potato protein that helps prevent hunger cravings and keeps one full for a longer time.

The other diet by the name HMR Diet is not very well known but has been around for a very long time. The diet was used mainly in hospitals and weight loss clinics to lose weight fast when it was required. However, they’ve also made their diet available to people at home.

The HMR diet consists of weight loss shakes and entrees that are low in calories.

It is advisable to consume 1 to 2 servings of fruit and veggies per day in conjunction with the HMR diet.

The great thing about this diet is that it is very simple to implement. To start the diet, all you need to do is order a 3 weeks starter kit.

What Users Are Saying

What Users Are Saying

“This item really works with the diet plan I have been on. The taste is great and I have ordered several times already.”

Bottom Line

The Bottom Line on WonderSlim

So now, what do we have to say about this one? We were excited to write about Wonderslim because of their realistic results and the benefit of a low-calorie diet. We like the ease of ready-to-eat meals and the customer testimonials online, but without research proving that it performs better than more affordable options, we don’t feel comfortable recommending this as a weight-loss product. We’re also concerned about the poor taste and texture that many dieters complained about and the high cost.

When you finally get tired of the merry-go-round that is yo-yo dieting, there’s a program available that’s clinically proven to help get you on track and keep you there for the long haul.

Among the best weight-loss apps we’ve seen this year is Noom. This app isn’t like all the others on the market. It is clinically proven, designed by doctors, and maintained by nutritionists. Did we mention that it’s clinically proven to help you lose weight and keep it off?

55 WonderSlim Reviews

  • I love it so far!
    Wendy (Verified Purchase)

    I just started WS’s 12wk program. I’m 3wks in and I’ve lost 10 lbs! I’m not hungry and even had a couple of bad days the first wk trying to get used to it. I didn’t like some of the food choices so I sent them back for things I really did like, like their veggie chili(delicious). It also is making me think more about wht I eat. I love it so far!

  • I have just order my first supply of WonderSlim products.
    juju (Verified Purchase)

    I have just order my first supply of WonderSlim products. For those of you that have stated that there are not nutritional facts, you just need to click on the individual items and all of the facts are listed under the tab “Nutrition Facts”. Hope this helps!

  • The food is better.
    DeeDee (Verified Purchase)

    I am on the WS Diet, and I used to be on Medifast. The reason why I love Ws is:

    1. Its hundred dollar cheaper,
    2. You can eat a piece of fruit, 3. The food doesn’t taste like wallpaper paste, 4. When you order it doesn’t take forever like medifast. You can actually eat 2 starches on this diet and still loose weight. 6. You can also have milk and even yogurt with your breakfast.
    7. The food actually taste like food. 8. Compared to medifast 5 & 1 plan there plan will make you feel full for example for breakfast I ate:
    1 smoothie
    1 bowl of cereal w 4 oz of milk.. Also I havent gotten any huger pains or headaches.. I am actually full!! I dont have the time to think about fast foods..Because the time you eat your last snack or try to, your belly is satisfied.

    The food is better, especially the oatmeal and they actually do provide regardless of what the moderator states the calories are not on the items. Just try WS and see for yourself compared to Medifast.. I am a believer and never looking back.

  • Wonderslim provides more than just bars, shakes and puddings
    pat (Verified Purchase)

    On the Diet Direct website not only is there nutrition information for Wonderslim products, there are also consumer reviews, very candid reviews I might add. I have transitioned to this plan from MF and have to say the food is much better tasting and cheaper box for box than its rival company, MF. In this economy, this is a major plus. I really like the plan overall. I am never hungry and can have a piece of fruit which in my opinion is another plus. About the suppressants: if the plan is working, why would you need an appetite suppressant? If you need an appetite suppressant, the site sells them. Another thing, Wonderslim provides more than just bars, shakes and puddings. They also provide entrees like Vegetarian Joe, Cheeseteak Macoroni, Omelets and breakfast items.
