B. Wonderslim Overview

What Is Wonderslim?

This is a popular meal replacement system that seems to actually work. It encourages you to replace your usual meals with the company’s products. Supplements like snacks, bars, and shakes are all part of the equation. Wonderslim is well-known for its wide range of possibilities and large options of ingredients.

Wonderslim’s parent company is Diet Direct and this diet was created in 2001. It has some longevity and the products are great when it comes to limiting your caloric intake.

How Does It Work?

All Wonderslim supplements and meal replacements come as diet kits (see here for selections). Each diet kit will help you start your challenging yet rewarding weight loss journey. These shakes, drinks, soups, and bars are customized for both men and women. One meal plan contains 1000-1200 calories for women while for men, these plans provide between 1500 and 1800 calories per day.

You must enter on the company’s official page and become a member of the program. Then, you will receive a clear shopping list that will guide you and teach you what foods are allowed and what you should avoid buying. Besides its own meal replacements, this diet focuses on lean meat, vegetables, and starch. As long as you will stick to this program, you will definitely achieve your weight loss goals.

The Most Popular Product – Wonderslim Shake

The most popular products of this diet are the shakes which are super convenient. To prepare them, you must combine one serving of powder with milk or water. If you don’t have a blender, don’t fret about it! You can simply use a spoon to mix this shake. Another alternative is to purchase Wonderslim ready-to-drink beverages that don’t require any preparation.

The taste of Wonderslim shakes is more than pleasant and there are a lot of flavors to choose from such as chocolate, strawberry, vanilla, coco mint, hazelnut, and more. One shake costs on average 1.80 dollars and it provides 15 grams of protein.

Medifast vs Wonderslim – Bottom Line

a. Diet Approach

Medifast and Wonderslim focus on low-glycemic meal replacement programs for fat loss. They will make your body speed up its metabolism and burn fat a lot quicker than usual. During these diets, you will be required to eat special meals such as shakes, nutrition bars, oatmeal, and desserts once every couple of hours a day, and here are some of the best Medifast foods to eat to lose weight.

One thing that sets Medifast apart from Wonderslim is the option to purchase frozen low-calorie green meals if you don’t want to spend time preparing your own meals. Wonderslim does not offer that possibility.

b. Cost Comparison

Wonderslim can be cheaper than Medifast but that depends on the pricing option you choose to buy. The basic pricing plan costs at least 7 dollars per day but you receive only four meals a day. The same basic package provided by Medifast offers you five meals a day.

Wonderslim’s medium-priced plan is approximately 8 dollars per day and it includes five meals. However, it contains only shakes, snacks, and bars. On the other hand, Medifast also has entrees and desserts.

The premium plans of both these diet programs are quite similar. They cost around 11 dollars per day and they offer the complete package, including dinner entrees and desserts. So, it all comes down to what type of meals and diet plan you want to follow. Overall, Wonderslim is more expensive than Medifast.

c. Weight Loss Results

Both Medifast and Wonderslim promise the same thing: to help you lose weight easily and quickly. Those who choose to follow the Wonderslim diet usually lose a maximum of four pounds per week. According to Medifast’s research, their dieters seem to lose up to five pounds per week.

d. Online Support

Wonderslim provides clear diet instructions as well as an introductory kit. Still, you will not receive any online support whatsoever. On the other hand, Medifast offers plenty of online support such as forums, recipes, message boards, and emails.

Final Verdict: Medifast or Wonderslim?

Both Wonderslim and Medifast diets are similar diet programs that offer nutritious meal replacements.

They promise to help you shed those extra pounds in no time and keep them off with long-term weight loss. Both of them are recommended and approved by doctors. Something that sets Medifast apart from Wonderslim is its highly effective online support.

Wonderslim might be more of a DIY plan during which you must compose the meals on your own but, at the same time, it has more flexibility compared to Medifast. So, the secret to choosing the best diet program lies in what your goals are (goal weight, etc…).

  1. Go With Wonderslim IF you want something more flexible with multiple kits and plans to choose from.
  2. Go With Medifast IF you just need a clear dietary plan that you can follow closely. NOTE: You can save $100 off of Medifast here.
Why Go with Wonderslim
