    First the bad stuff - I don't like all the shakes and some meals are pretty bland, so I wasn't fully satisfied with my first order. Now the good stuff - the second delivery was perfect, just skipped what I didn't like the first time and loved every bite. So far, I've lost 6.5 pounds (2 and a half weeks), which is more than I managed to lose in the past couple of years. Worth the cash, that's for sure.
  • Submitted By Georgia Adams on 12/18/2017
    Fair prices, customer support is lovely, and I did lose a few pounds, 3 pounds in 10 days to be exact, so an honest recommendation from me.
  • Submitted By Linda Smith on 09/11/2017
    Probably the tastiest diet meals I've had. I like that it's not so strict, that I can choose when I want to have a meal replacement, when I just want to heat up a meal, and when I want to cook. 4 pounds isn't much, but I've been struggling with weight for a long time and this has really helped me believe that I can do it. I'm more than grateful!

    Tried this a couple of years ago. The food takes some getting used to but it works! I lost 25 lbs in about 3 mos. You have to stay on the plan or at least a modified version of it. Gained back 30 and can't seem to get it off again, even using Medifast :/

    Just wanted to work on maintaining my current weight with a diet plan that is easy to use and that doesn’t take too much time. Medifast doesn’t offer too many pre-made diet plans, but the ones they do are perfect and easy to use. Just had a go with a 30-day Select Kit and I’m very happy with the results. I’d recommend it to every health conscious person.

    You rarely find a meal delivery service that is able to cater to a specific condition I’m having to live with. Chronic arthritis and gout are very hard to live with, but with the help of dedicated dietitians I’ve managed to formulize a diet plan that helped me very much. Medifast is a great choice for a plethora of people with different health conditions.
  • Submitted By Andrew on 08/05/2016
    If you’re able to get used to snacks and crunch bars, Medfast is for you. I wasn’t able to fully enjoy the flavor in any of the snacks provided in their packs. All that kept me through the program were a couple of meals with a flavor of home. And the fact that I actually started to lose weight. I guess taste and health rarely go together, will have to continue the search.
