Medifast vs. Wonderslim - Our In-depth Comparison for 2022

Both of the services provide plenty of snacks, bars and shakes, while they leave cooking 1-2 meals a day to the customer with guidelines for acceptable ingredients. They have plans suitable for nursing mothers, diabetics and vegetarians and people requiring kosher food.

There are many options for allergy sufferers, with Medifast offering a specific gluten-free meal plan, while Wonderslim provides gluten-free options. Both have vegetarian meals, although Wonderslim offers a vegan option too. 

Medifast offers three basic plans to their customers: GO!, Achieve (there are two different varieties within this plan), and Thrive. While GO! and Achieve are designed for weight-loss, the Thrive plan is used to maintain a healthy weight once it has been reached. While the Achieve Plan leaves the preparation of two meals up to the customer, the GO! plan only requires customers to cook one of their own meals, with provided guidelines and recipes.

Wonderslim offers three basic plans: Essentials, Classic, and Complete. All three come in varieties specially designed for men, women, diabetics and nursing mothers. These include meal replacement shakes, meals, and delivery of ingredients with which customers can prepare dinner themselves.

Wonderslim promises its customers food made in FDA-inspected facilities in the USA. Many of their products are free from aspartame, and clear labelling allows customers to choose between products containing aspartame, and aspartame-free ones. Medifast, on the other hand, uses only natural colours. Although both services use healthy, nutritious ingredients in making their products, our choice here is Wonderslim. If the FDA approves, so do we!

With both Wonderslim and Medifast, customers can eat 6 times a day, which means eating every 2-3 hours. Eating small portions frequently helps to keep hunger at bay. The food is specially designed to be low in calories, but high in nutritional content such as protein and fibre. Wonderslim gives customers supplements to take together with their diet, making sure that no vitamin or mineral is missed.

As mentioned above, Wonderslim and Medifast both enable customers to cook 1-2 meals a day themselves. Therefore, both services offer more shakes, snacks and bars than they do ready-made meals. However, Wonderslim provides a far greater variety of products, with 150 options by comparison with Medifast’s 65.
