Our Comparison

Meal Plans

Atkins helps you stay on a low-carb diet while enjoying food. You can order their frozen meals, nutrition bars, shakes, treats, powders, etc. Atkins 20, Atkins 40, and Atkins 100 are three types of nutrition Plans. Shakes come in Tetra Pak’s to stay fresh up to a year without refrigeration. Prices of shakes go from $7.19 to $8.89, and for bars, you would have to pay from $6.89 to $8.89. Meals come frozen and shouldn’t be thawed before microwaved. Although a lot of customers complained about getting already melted meals without any ice left inside! We hope they solved this problem!

Medifast offers three Plans – GO, ACHIEVE, and THRIVE. Medifast GO is for fast and efficient weight-loss; ACHIEVE is for graduate weight-loss while THRIVE is for maintaining perfect weight and lifestyle. Daily Menu contains 4-5 meals, Lean and Green meal, and one snack. Thrive Plan includes shakes, smoothies, and bars, as well. Medifast features guides to help people allergic to gluten, diabetes type 1 and 2, nursing moms, and seniors.

The Quality of the Ingredients

Atkins doesn’t tell much about the ingredients of frozen meals. Food isn’t organic and Non-GMO but still is healthy enough to justify the price of a meal kit. Medifast also isn’t transparent about ingredients quality. One thing is for sure – they use only natural food colors.

Nutritional Value

Atkins diet is based on limiting the input of carbohydrates so that way body will burn fat instead of sugar for fuel! Depending on a diet phase, your daily input of certain ingredients will vary! Portions aren’t that big, but they are frequent plus the shakes, snacks, and treats. 

Medifast dietary Plans have a Lean and Green Meal which you can design by choice and is mandatory each day! All of the 65 meals are low-fat, low-calorie, high-protein, high-minerals! Medifast shakes and sweets are also highly-nutritive and delicious, encouraging you to keep on with a diet!

Recipe Variety

With Atkins frozen meals there’s no much to say about recipe variety. You have 14 meals inside of a kit, different in essential protein and added flavors – poultry, beef, Mexican style, Asian style, pasta, vegetarian/vegan recipes, etc. Both Atkins and Medifast feature entrees – breakfast, lunch, smoothies. Medifast gives more attention to senior and nursing mom’s recipes and diabetic-friendly menus as well.

The Packaging

image of Atkins package

Neither Atkins or Medifast didn’t make this easier for us! They don’t give any information on how food is packed in a box, so we’ll share these very few information we have! Atkins orders are shipped via FedEx and UPS, without any shipping fees for all orders above $99. There’s an option for a Rush Delivery (price is $20 per box). If you live on Alaska or Hawaii, then you’ll have to pay shipping $60 per box.

The company sends an email with a link where to track your shipment. Already mentioned customer review on thawed meals is a shortcoming. Medifast orders are processed and shipped within two business days. Only Medifast Advantage members have benefits with shipping fees and discounts!
