Note: This review is based on my own research + analysis of WonderSlim.

As such, if you're considering a meal plan that's ideal for weight loss, I happen to know the best option.

  • Many complaints regarding the flavor of the food



WonderSlim In A Nutshell

WonderSlim is a diet that consists of meal replacements, helping you lose weight.

This means that you get the necessary calories daily in a convenient way.

As such, the most charming advantages of such an approach would be ease and accessibility.

In short, here's what a meal replacement diet consists of:

  • heavily reliant on liquid food
  • implies a minimum amount of meal prep
  • makes it easier to keep track of calories

In truth, while this type of diet manages your calorie intake pretty well…

It also cannot replace traditional meals forever, since it is not preferable over time.

Right from the start, we set off with the idea that this service is not for everyone.

However, a pleasant surprise is that WonderSlim does not work based on a subscription.

This program offers 3 tiers to choose from when ordering a box…

But be aware that you cannot control what you receive upon delivery.

In fact, this is one of the complaints customers brought up, along with:

  • the food's taste being unbearable
  • issues when it comes to returns

Affordable as WonderSlim may be in comparison to other competitors…

It doesn't help much if the flavor of the food makes it inedible.

Besides, there's also the fact that this type of diet is not safe for people who are allergic to gluten or are lactose intolerant.

Plus, if you're either vegan or vegetarian, the same concept applies.

This, of course, adds to the idea that while WonderSlim is accessible financially…

It's not inclusive enough when it comes to people with dietary restrictions.

All in all, while this service is not all bad…

There are surely much better alternatives out there.




#1 – What Is WonderSlim?

Basically, WonderSlim is a diet that follows a meal replacement system:

  • substitutes solid food for a bar, drink, soup, etc.
  • is more accessible than a solid meal
  • is less time-consuming

As such, this method is intended to keep you satiated while also providing you with just enough nutrients.

Given this model, you are expected to take care of the meal prep.

However, don't worry, because shakes don't require a long time to get done.

Depending on which plan you choose, you might be required to do more or less work.

But you're not expected to cook up intricate meals from scratch.

So you won't find yourself spending huge amounts of time in the kitchen.

Essentially, the high amount of protein in WonderSlim products will keep you full.

That way, you won't feel like you're starving.

In this way, you will also lose weight because you will get away with eating fewer calories.

It's also handy that this diet program offers many healthy alternatives to fast food recipes.

This essentially means you get to enjoy the taste of your favorite dishes…

But with a healthful spin!

That being said, here are the options you have to choose between for WonderSlim:

  1. Basic Plan – includes 4 portion meals per day.
  2. Core Plan – consists of 5 meals per day.
  3. Premium Plan – offers 7 meals per day, plus desserts.

As you can see, the number of substitute meals you get is tied to the tier of your plan.

On top of this, your delivery box will also include:

  • multi-vitamin supplements
  • shopping list
  • food diary
  • EFA softgels
  • blender bottle

These items are essential for your weight loss journey, so it's nice that they're also present.

The shopping list and food diary should help you stay on track.

As such, you would be less likely to drop the diet, so it's definitely helpful.

Besides, they also give a 30-day money-back guarantee.

So if you try the WonderSlim products and decide they're not for you, it's not a waste.



#2 – How It Works & History

It's time to look at the basics of WonderSlim:

  • how it takes action
  • whether or not it's for you
  • its history
1. How It Works

The official website describes WonderSlim as a “nutritionally balanced, high protein, portion-controlled weight loss program”.

It also claims that this diet provides faster and more effective weight loss.

More than anything, it is also mentioned that consistency and ambition are the keys to success.

Obviously, in this perspective, any of the three diet plans mentioned earlier should work fine.

That being said, the amount of daily calories you get depends on your gender:

  • 1000-1200 calories per day for women
  • 1500-1700 calories per day for men

The official website also lets you download a file with instructions for your respective plan.

In this file, you can find details such as nutritional facts as well as instructions.

There is also an example of what you can eat in a day, to get you started.

Additionally, keep in mind that WonderSlim expects you to drink at least 8 cups of water per day.

They mention that hydration is a huge factor when it comes to shedding extra pounds [1].

Now – how does WonderSlim help you lose weight exactly?

Well, it can do that by creating a calorie deficit. 

If you consume fewer calories than you normally would in a day, your body breaks down body fat to make up [2].

This is what leads to the weight loss this program talks about.

Since it offers up to 7 meals a day, expect them to be pretty small and just enough to stave off your hunger.

Over time, this should yield good results.

2. History

There is very little information regarding how WonderSlim or DietDirect started.

If you go to their “About Us” page, they tell you all about how confident they are in their products.

They also mention WonderSlim and how it's backed by a 100% satisfaction guarantee.

The location of their headquarters is disclosed to be Wilmington, NC.

Other than that, DietDirect expresses empathy for anyone willing to take on a challenge as huge as losing weight.

In essence, we are not given details as to how everything began.

It seems like this page is just for creating a parasocial bond with the potential customer.




#3 – Weight Loss Plans (6 out of 10)

I previously mentioned that all tiers of their diet plan are good for weight loss.

It is time to take a closer look at what each of them has to offer.

To make things easier, we're going to go by the 4-week variant for every option.

Let's look at the details together.

1. Basic Diet Plan

Here's what the 4-week basic plan has in store for you:

  • 84 meal replacements
  • 28 bars & snacks
  • 20 oz. shaker bottle
  • multi-vitamin supplements
  • food shopping list
  • food diary

All these things included, one meal costs you $1.84.

Considering that you're supposed to eat 6 times every day, this plan is pretty easy on your wallet too.

Given that it's a lower tier, you won't get as many benefits.

But it's good enough to give you a taste of what WonderSlim is like.

2. Core Diet Plan

Time to look at the 4-week core plan:

  • 84 meal replacements
  • 28 lunch supplements
  • 28 bars & snacks
  • 20 oz. shaker bottle
  • multi-vitamin supplements
  • food shopping list
  • food diary

As you can see, this plan also offers to substitute your lunch instead of letting you fend for yourself.

Unlike the previous plan, you have to prep less on your own.

Plus, the difference in price is pretty insignificant compared to the basic plan.

So you're not losing much by getting a higher tier of this program.

3. Premium Diet Plan

Let's look at the 4-week premium plan:

  • 84 meal replacements
  • 28 breakfast supplements
  • 28 lunch supplements
  • 28 bars & snacks
  • 28 dessert supplements
  • 20 oz. shaker bottle
  • multi-vitamin supplements
  • food shopping list
  • food diary

As you can tell, this plan covers every main meal of your day.

On top of that, it also comes with desserts, so you don't have to go buy them every time.

This is why Premium is the most expensive plan out of all of them.

However, it's also the most complete one, by the looks of it.


It seems like the main difference between the programs is the number of meals they substitute for you.

As such, you are left to choose how much you want to control your own diet…

Versus how much you want to depend solely on WonderSlim.

Other than that, it also depends on the dietary restrictions that may or may not apply to you.

For example, WonderSlim is not ideal for those who are lactose intolerant, vegan, vegetarian, or allergic to gluten.

That being said, you have to be very cautious with this diet if there are ingredients you are not okay with.

Because of this, a more inclusive weight-loss program might interest you more.




#4 -Meals & Menu (6 out of 10)

The time has come to talk about the tasty bits of this review.

Without further ado, let's take a look at the meals you can look forward to with WonderSlim.

1. The Menu

As I already mentioned, the menu is based on 6 meals per day.

Given that WonderSlim is mainly about meal replacement…

It makes sense that shakes are a very significant part of this weight-loss program.

Keep in mind that WonderSlim offers a nice array of products to choose from when it comes to food.

Although there is a slight degree of customization to this service…

It's not guaranteed that it can accommodate people with strict dietary restrictions.

However, you might appreciate that WonderSlim does not force you into a subscription.

In fact, you are free to order from them however often you like and in any amount.

That is a degree of freedom that not many companies offer.

But be warned that ordering a meal plan directly does not allow you to pick and choose from their products.

At least this is what the Amazon reviews are saying.

Let's get to the actual products now.

2. The Meals

Since WonderSlim offers a selection of multiple types of products…

We will look at each category together.

This way – you get to see this diet's selection in all of its glory.

Now – here are a few of the meal bars you can get:

  1. Chocolate Almond
  2. Fudge Graham
  3. Dark Chocolate S'mores
  4. Shortbread Cookie

Next, here's what you can have in terms of actual meals:

  1. Cheesesteak Protein Pasta
  2. Spicy Cheese Protein pasta
  3. Zesty Chili with Beans
  4. Creamy Fettuccine Alfredo Protein Pasta

Because they are at the heart of this diet, here are some of the shakes & smoothies you are offered:

  1. Chocolate Salted Caramel Meal Shake
  2. Strawberry Cream Meal Shake
  3. Berry Yogurt Meal Smoothie
  4. Cocomint Cream Meal Shake

Moving on – if you're thinking about breakfast, there are a few possibilities:

  1. Maple Brown Sugar Protein Oatmeal
  2. Granola Trail Mix Variety Pack
  3. Protein Pancake & Waffle Mix
  4. Apple & Cinnamon Protein Oatmeal

Don't worry about desserts & snacks because they also have you covered there:

  1. Blueberry Protein Mug Cake
  2. Pizza Protein Crisps
  3. Honey Mustard Protein Crunchers
  4. Protein Pudding Variety Pack

Not to mention that they also prepared some drinks for you:

  1. Protein Hot Chocolate
  2. Protein Cappuccino
  3. Protein Hot Chocolate with Marshmallows
  4. Very Berry Fiber Drink

For the vitamins they mention in their plans, here's what I could find:

  1. WonderVites Essential Fatty Acids
  2. WonderVites Multi-Vitamin

Honestly, these all sound quite nice.

Another great aspect is that you can check all the nutritional facts of each product on its respective page.

That way, you can make a better judgment when it comes to what best suits your lifestyle.

Besides, you don't even need to order the meals in order to see the recipe.

That's because the cooking directions are right with the rest of the info – online!

So you can take into account everything when deciding what you want the most.

Now, of course, WonderSlim does not offer 100% ready-made meals.

However, the level of prep it requires is also not excessive.

But if that's not for you, feel free to look for something else.




#5 – Results (6 out of 10)

WonderSlim has been on the market for quite a while.

This means there has been enough time for people to wrap up their thoughts regarding this diet.

So let's see what customers have to say about this program, shall we?

Note: I only considered authentic reviews, not promotional/fake ones.

1. Positive Reviews

The trend of avoiding the official website when it comes to user reviews continues.

This is because it's much better in terms of objectivity to look at 3rd party websites.

In this case, however, we can check Amazon, which is pretty popular among buyers.

Let's see what people enjoyed about WonderSlim:

  1. Many people were happy with the taste of their products.
  2. Quite a few also mentioned they managed to lose weight.
  3. A few also said they feel full while on this diet, so they are not starving.
  4. They also appreciate the ease of use of this diet plan.
  5. Some people also said this program compares to other more expensive alternatives.

Someone even mentioned they managed to shed 7 kilograms (15.4 pounds) in 7 weeks:

This is pretty impressive, and it also confirms that WonderSlim works as it should.

All in all, the amount of people praising this diet is not negligible.

Knowing that it also plays well into your weight-loss journey is a plus.

However, let's not forget to take into account the opposite side of the coin.

2. Negative Reviews

Much like anything that ends up on the Internet, WonderSlim was also met with negativity.

But that's not necessarily all bad, because the less favorable reviews help us consider things that we never thought of.

In short, whenever you're considering a purchase, make sure you're also looking at the negative reviews…

And not just at the people raving about it.

That being said, here's what people disliked about this program:

  1. People were complaining about the taste of the products.
  2. They also said the products they were sent were not the ones they were hoping for.
  3. Someone mentioned you have to stir the shakes for too long if you don't want lumps.
  4. Lots of people did not like the surprise factor of what you're getting upon delivery.
  5. A few people also mentioned the products made them sick.

A person even said they had trouble returning the plan and they were charged for more:

Honestly, the fact that quite a few people complained that they couldn't put up with the taste is worrying.

This means that they can't even go through the diet properly.

When it comes to anything food-related, the taste is really important.

Plus, the fact that you're not in control of what you receive unless you order everything separately…

Is rather inconvenient.


All in all, it seems like the user feedback is rather contradictory.

While some people praise the taste of the food, others say it's nothing to write home about.

It may be true that this program is helpful for weight loss, but if the taste is not enough to keep people interested…

Then it's all for nothing.

Not to mention that it's also pretty sketchy if some people were having issues with returning their box.

That is indeed pretty suspicious as far as customer care goes.

I would say you're better off looking for something more special.




#6 – Side Effects (6.50 out of 10)

As you may have seen, not a lot of user reviews mention much regarding side effects.

This makes it difficult to assess just how much risk this diet involves.

Regardless, here are a few adverse reactions to keep in mind if you're drastically changing your diet:

  • bloating
  • fatigue
  • very low energy

These are to be expected in such circumstances.

It's best to keep an eye out for them and monitor your body's development.

In more extreme cases, you might even experience diarrhea and/or abdominal cramping.

And don't forget that consuming spoiled food can easily lead to food poisoning.

Since WonderSlim doesn't deliver food that is 100% ready-made, a risk like this is not that likely.

Still, it's better to be aware, just in case.



#7 – Price (8 out of 10)

You may already know that diet plans are not exactly affordable, right?

Well, let's see how true this is for WonderSlim.

Allow me to show you the price details.

1. The Exact Price

For the sake of consistency, I will list the price for every tier available for 4 weeks.

That way, it's easier to compare the differences between every option you have.

With that disclosure out of the way, let's see what we are dealing with:

  • Basic Plan (4 weeks) – $206
  • Core Plan (4 weeks) – $244
  • Premium Plan (4 weeks) – $321

On top of this, you can also choose a Starter Plan of just 1 week.

This is good if you want to give this program a shot without too much commitment.

Depending on whether you choose the Basic variant ($69), Core ($79), or Premium ($99)…

The price will fluctuate.

However, as you can tell, WonderSlim is definitely not the most expensive diet plan out there.

This is to say that, in the grand scheme of things, it's rather affordable.

But whether or not it's actually worth purchasing is another story.

2. Competitor's Price

If you're looking to buy a diet plan for yourself, there's no need to jump the gun just yet.

Allow me to tell you about my top recommendation for a weight-loss meal plan – Nutrisystem:

  1. If you want to lose weight in a reliable way, Nutrisystem is much better.
  2. Compared to WonderSlim, it also lets you pick out whatever you want to be delivered.
  3. In case menu diversity matters to you, Nutrisystem won't let you down.
  4. Instead of meal replacements, my recommendation gives you actual meals.
  5. Not to mention that Nutrisystem doesn't expect you to do any meal prep.

Keeping all of this in mind, I assure you that Nutrisystem is the best option here.

Not only does it keep you full by giving you substantial, solid meals…

But it also offers a lot more customization while also sparing you the meal prep.

So not only is Nutrisystem good for keeping you satiated…

It also saves you time!


It is true that WonderSlim is on the lower end of the spectrum when it comes to price.

Still, this is probably the best advantage this diet has.

Other than not overworking your wallet, it is not that special.

Not to mention that you can't really pick and choose what you are delivered.

Other alternatives give you a lot more freedom for your money.

So I would say it's worth keeping your eyes peeled for a better alternative.




#8 – Final Conclusions

Time to look at the main ideas regarding WonderSlim.

1. Based On Meal Replacements

This is a core distinction between WonderSlim and other diets.

Going into a weight-loss program based on meal replacements means you will consume lots of liquids.

Obviously, such a change can impact your body quite significantly.

Keep in mind that a diet like this is not for everybody.

Not to mention that on top of eating 6 times a day, you also have to drink at least 8 glasses of water.

If this is too much liquid for your body, don't feel like you need to keep going.

2. The Random Factor

According to user reviews, you actually cannot pick what you receive when ordering this diet.

That's quite a shame because WonderSlim has quite a few options for food.

Not giving you the option to pick and choose definitely counts as a missed opportunity.

The fact that they offer many flavor options for core products such as snack bars or shakes…

But won't allow you to input your preferences is pretty strange. 

3. Easy On The Wallet

One cannot simply ignore how affordable WonderSlim is.

Especially when compared to other similar services, it's nice to encounter something more modest.

As such, this makes it an accessible option for people with a tighter budget.

Not to mention that you also don't need to worry about a subscription.

Thus, if you're curious enough, WonderSlim wouldn't be the worst option to explore.



My Verdict – Worth It Or Not?

Short answer: So-so.

While WonderSlim is not exactly bad, it's just average:

  1. Based on meal replacements.
  2. Expects you to do some meal prep.
  3. Not gluten-free, dairy-free, vegan, or vegetarian.
  4. You have to eat 6 times a day.
  5. No control over what products you receive upon ordering.
  6. Quite a few complaints about the taste of the products.
  7. Decent price tag.

Therefore, WonderSlim is simply unimpressive at best.

If you are looking for a weight-loss program, please know that meal replacement is not outright unhealthy…

But it definitely cannot compare to having a traditional meal.

Because of this, I would definitely suggest an option that keeps you satiated with solid meals.

Naturally, if you can avoid processed meals, you should.

That being said – do you recall my mention of Nutrisystem?

I assure you it's my top recommendation for a weight-loss meal plan:

  • high efficacy in terms of weight loss
  • very affordable considering its quality
  • offers a high degree of customization
  • your meals arrive ready-made

As such, best believe that there is not much competition when it comes to how good Nutrisystem is.

So if you're still looking for the ideal weight-loss meal service…

Believe me when I tell you there is nothing better.
