Medifast Review

Medifast is a weight management service that people can use to have nutrient-dense and vitamin-fortified meals delivered right to their doorstep while learning how to live a healthier lifestyle.

Physician-developed and clinically proven, Medifast is a brand recommended by more than 20,000 doctors since its founding in 1980. It’s also accredited by the Better Business Bureau with an A+ rating.

Key Features

In addition to offering meals that are nutrient-dense, Medifast goes the extra mile to ensure that all of their meals are fortified with 24 vitamins and minerals. It also helps that each meal is designed to have enough low-fat protein and healthy fiber to help you feel full and satisfied between meals—a key to any successful diet.

And to ensure consistency, effectiveness, and safety across all of their meals, Medifast employs a Scientific Advisory Board of scientists and doctors; a board that also helps develop new meals, supplements, and alternate weight-loss approaches for those with special medical or nutritional needs. This helps Medifast be able to constantly develop new options for people with specific needs or preferences, such as those with health complications or already following specific diets.

For example, Medifast offers specific weight loss plans for:

Further speaking to their commitment to science, clinical studies have actually proven that Medifast’s methods work in helping people lose and manage their weight, with studies using Medifast being included in such publications as Obesity Science & Practice and the International Journal of Obesity.

Note: You can visit Medifast’s site to read the specific studies.

Medifast’s process offers a two-pronged approach to weight management. Not only do they offer the food and support necessary to lose weight through their Medifast GO (for quick weight loss) and Medifast ACHIEVE (gradual weight loss) plans, but through their Medifast Transition, Maintenance, and Exercise Plans, Medifast also helps teach its customers how to sustain their weight-loss results long term.

This sustainable approach could label Medifast’s service as more of a lifestyle change than just a barebones diet.


Medifast essentially offers four categories of plans:
