Wonderslim vs. Nutrisystem 2023: Which One Wins?

Can you lose weight following a carefully crafted daily menu? According to Nutrisystem and Wonderslim, you can. These two weight loss programs help you create a personalized menu and provide you with guidance for a better, healthier lifestyle.

So does it work? Both companies use low-calorie nutritious meals together with portion control to help your body kickstart the weight loss process. But I’m curious about the type of food you can get, the overall experience, and whether the results last.

Overall, I think Nutrisystem is better if you want long-lasting results and to learn how to build a healthy daily menu. To see if you agree with me and whether Nutrisystem is for you, keep reading.

Menu Variety

Winner: Nutrisystem

Both companies offer a varied menu with options for a wide range of dietary needs and preferences. However, there’s a clear difference between the two when it comes to the type of meals offered. 

Wonderslim’s menu includes only meal replacements, packed breakfast options (pancake mix, cereals, smoothies, protein shakes, and so on), instant soups for lunch, and high protein dessert options like hot chocolates and puddings. 

In short, Wonderslim’s offer doesn’t include ready-made meals or even meal kits to help you prepare your own foods. Instead, it offers over 100 options of meal replacements, shakes, bars, snacks, and smoothies that will help you keep portions and calorie intake under control throughout the day.

The Wonderslim system has you eating six to seven times a day (whether you’re hungry or not), of which at least four are Wonderslim meals. You’re encouraged to eat one or two real meals as well, but you’ll have to do the shopping and cooking. 

On the other hand, Nutrisystem’s menu contains a combination of frozen meals and microwave- or oven-ready foods for breakfast, lunch, dinner, and snacks. Nutrisystem separates its meals into two main categories (for men and for women) in order to provide you with options that fit your caloric and nutritional needs. 

Just like Wonderslim, Nutrisystem recommends eating around six meals per day. However, unlike Wonderslim, you’ll receive ready-made meals that are either frozen or ready to pop in the oven or microwave. 

Overall, Nutrisystem offers fully prepared meals, made from quality ingredients and portioned for weight loss. Each meal combines healthy fats, lean protein, and smart carbs to create a delicious and tasty menu. Plus, you get to try a variety of cuisines, from good old American to Mediterranean, Asian, and more.

Meal Customization

Winner: It’s a tie

Neither of the two companies allows you to add or remove ingredients from existing meals, but you have complete freedom in choosing which meals make up your meal plan menu. Both Nutrisystem and Wonderslim have an à la carte system, whereby you choose the number of meals assigned to the selected plan. 

Wonderslim is a bit more flexible and you can choose between one of the three weight loss programs (each available in two-, four-, eight-, and 12-week plans) or you can order any product you want, in any quantity, at any time – just like you would from an online store. 

Nutrisystem on the other hand only offers monthly deliveries, so you have to build your plan for the entire month (which is a bit tedious and time-consuming). However, Nutrisystem lets you choose if you want to leave menu building in the hands of the specialists (Chef’s Choice) or if you want to be in full control and choose your own meals. 

Plus, Nutrisystem has an entire collection of shakes specially designed to support weight loss. These aren’t included in the main meal plans and come as an extra.

Lastly, both Wonderslim and Nutrisystem have options for a wide range of dietary needs such as vegetarian, diabetes-friendly, keto, paleo, low-sodium, and so on. However, the only one that offers a comprehensive filtering system while choosing your meals is Nutrisystem.

Ordering, Delivery, Unboxing

Winner: It’s a tie

To place an order, both companies require you to create an account. This is easy to do and only takes a minute or two. Once the account is created, you can place your first order and choose the delivery frequency.

With both, it’s easy to tweak your plans, switch between plans, or cancel your current and future orders. Nutrisystem even has a money-back guarantee (within 14 days of delivery) if you’re not happy with your order. Wonderslim also has a flexible returns policy and will take back any unopened and undamaged products in exchange for a full refund. 

In terms of delivery, both services use FedEx and deliver all over the continental US. Nutrisystem has a 10-day delivery window (but most boxes reach their destination in seven days) while Wonderslim’s is two to five days. Also, both services will email you a tracking number so you can check your box’s status.

Since the Wonderslim boxes don’t contain fresh or frozen ingredients, the packaging is quite regular, with a combination of cardboard, paper, and plastic. However, the company doesn’t specify which of these are recyclable.

Nutrisystem’s packaging is different and the company even goes so far as to send frozen foods in a separate box (non-frozen foods have their own box). The frozen food is packed in a special box that uses dry ice to keep everything inside cool. These cooling boxes are 92% biodegradable and can be recycled at any local center.

Once you receive the Nutrisystem box, it’s important to place the frozen or ready-made meals in the fridge or freezer (prepare to dedicate a lot of space to this). The rest of the foods (Wonderslim included) are shelf-stable so you can keep them in a cool, dry place.

Meal Prep

Winner: It’s a tie

Both Nutrisystem and Wonderslim make sure the meals are ready quickly, with minimum prep time. Most Wonderslim products will require you to add some water or milk (depending on the dish) and, if necessary, a few minutes in the microwave or on the stove.

Nutrisystem’s meals are just as easy to prepare, but frozen dishes may require a bit more time in the microwave or oven. Each meal comes with heating/prepping instructions, so make sure to follow the instructions on the box.

Overall, both companies try to make things as easy as possible for you. Everything’s ready for you to prepare and enjoy in under 10 minutes (including cleanup).

Customer Support

Winner: Nutrisystem

Both Nutrisystem and Wonderslim have extensive FAQ sections where it’s easy to find detailed answers to some of the most commonly asked questions. Plus, each website offers user reviews for the listed items, so you can check what other customers say about things like taste, results, and more. 

Honestly, I found the reviews extremely helpful when placing my first order, since it was difficult to tell which meals would work best for my needs. 

In terms of customer service, both companies have a readily available team, so you can get in touch easily. However, I found Nutrisystem more approachable since they offer three methods of communication (phone, email, and chat), compared to Wonderslim’s two methods (contact form and phone).

With both companies, you won’t have to wait long to get a reply unless the team is backed up. If this is the case, you’ll see a notification on the website. 


Winner: Wonderslim

Both companies offer three main plans, each including a specific number of meals. To get the lowest price per serving, you’ll have to purchase the plan with the most meals (this is the case for both Nutrisystem and Wonderslim).

Wonderslim’s plans include the Basic (four Wonderslim meals per day), Core (five Wonderslim meals per day), and Premium (seven Wonderslim meals per day). Each of these plans is available in bundles for one, two, four, eight, and 12 weeks. For this review, I used the most common one, which is the four weeks bundle.

In this case, the lowest cost per serving is $1.64 but if you want to get to the lowest possible cost per serving (Price: Missing Product wonderslim) you’d have to order the Premium plan for 12 weeks. 

Overall, I like the freedom provided by the Wonderslim plans since you don’t have to worry about auto-renewals. You can start with a one-week Basic plan ($69.99 for 30 items) to test the waters and decide if you want more. Also, you don’t have to pay for delivery as long as your order is $69+. There is however a $7.99 flat rate for orders below $69.

Nutrisystem calculates its costs per day, not per meal. For instance, the Basic plan is $9.99/day for women and $11.64/day for men and includes breakfast, lunch, dinner, and snacks (you can add shakes as extras, but that will cost another $40 or so). This means you’ll pay about $2.49/serving (without the extras). 

However, this price is only valid with an auto-renew monthly option. For a one-time order, you’ll pay full price, which can be quite expensive. You also have the option to pay for two or three months, to get a better price per day.

The Uniquely Yours Max plan will get you the best bang for your buck, at $14.29/day for men and $13.21/day for women. This price is for monthly auto-delivery without extras. While this may sound like a lot, keep in mind that this plan includes four meals per day, five days a week. You also have the option to choose the seven-day plan, which will cost $15.36/day for women and $16.61/day for men. 

Lastly, with Nutrisystem, shipping is free for all four-week plan orders (both frozen and non-frozen) whether it’s a one-time purchase or an auto-renew delivery. For à la carte orders, you’ll be charged between $7.99 and $19.99 depending on the value of your order.

When you flesh it all out, it’s quite clear that Nutrisystem's best price per serving (Price: Missing price for Product undefined) is higher than Wonderslim’s. However, if you factor in the fact that Nutrisystem also delivers ready-made meals, it’s easy to see why.

And The Winner Is: Nutrisystem

Wonderslim and Nutrisystem each offer a different take on weight loss programs. Wonderslim is more focused on short term effects (rapid weight loss) and, in doing so, builds a program that’s dependent on meal replacement products and shakes.

Nutrisystem plays the long-term game and helps you understand how to integrate various healthy foods into your diet. You’ll still have to deal with shakes and powders, but these usually come as extras.

Overall, I think that you have a better chance at lasting results with Nutrisystem. However, if you don’t have the budget for it (Nutrisystem can get expensive), Wonderslim is a cheaper alternative. Both programs deliver results and provide useful guidance for your weight loss journey.  


How much weight can you lose on Wonderslim?

If you follow the menu and guidelines provided by Wonderslim, you can lose up to five pounds a week during the first couple of weeks. After this period, you’ll still lose weight, but it will be at a slower pace.

What are the disadvantages of Nutrisystem?

Even though you can customize your menu from one month to another, it can get tiring to eat prepackaged foods. Plus, the portion size is small and you may feel hungry even though you’re encouraged to eat around six meals per day. 

Are there any health risks with Nutrisystem?

There have been no side effects associated with Nutrisystem foods, but if you are on a special diet, it’s best to talk with your doctor first. Nutrisystem doesn’t recommend its program to anyone who has a health condition or dietary restrictions.
