How Medifast Coupons Work:

They say that “there are two kinds of people in the world,” and such is the case with Medifast coupons. Here are the two ways of getting a discount at

  1. Signup Offers: These coupons are intended for new customers and are applied instantly when you click on a promotional link (no code needed). They yield up to a $100 discount on your first month when you signup for Go!™ or ACHIEVE with the “Advantage” auto-delivery program, and may include free shakes or food.
  2. Promo codes: Customers buying 30-day kits or a la carte food can enter a coupon code at checkout for a $15-35 discount. There is usually a $150+ minimum purchase required, and these codes won’t combine with other promotions.

OK, so the first method of getting a discount doesn’t need further explanation. Here’s more about Medifast promo codes:

How to Use a Medifast Promo Code:

If you’re making a one-time purchase of food or a meal kit on, you can use a discount code to save up to $50!

To do so, just finalize your selections, and then click to view your shopping cart. Under the “order summary” section, you’ll see a field that says, Enter promo code,” like this:

enter medifast promo code here

After the valid coupon code is applied, you’ll get a summary of the discount, including free shipping, or other free bonus items.

Promo Code Not Working?

Did you get a message saying, “The coupon code has expired”?

There are 3 reasons why a Medifast promo code doesn’t work:

  1. Membership promo codes require that you check the “Join Medifast Advantage” box
  2. Food promo codes are not valid for Medifast Advantage, Medifast’s auto-ship program. Uncheck the “Join Medifast Advantage” box and the code should work!
  3. Promo codes usually require a minimum purchase of $150-250+
  4. There are two boxes that say “enter promo code” at checkout. If a code doesn’t work, try the other box! (weird)
  5. Promo codes are CaSE SENSITIVE, and usually, they are all-caps!
  6. Promo codes are released each month, so your code may be expired

Here’s what the the “Join Medifast Advantage” box looks like:

*Note: Medifast automatically applies a discount to monthly orders with Medifast Advantage auto-ship. You may notice on membership orders that unchecking the Join Medifast Advantage box may cause your order total to increase, and you may not get free shipping.

What’s the Best Coupon?

The answer to that question depends on whether you are signing up for a new monthly plan, or buying food a la carte.

You might see Medifast banners like this:

Here’s are the best Medifast promotions to look for as a new customer:

  • GO!™ Plan: (fast weight loss) Right now the best sign up deal is the $100 Off + 7 Days free Meals coupon which includes free shipping. That’s about $100 in savings on top of the first month’s discounted price!
  • ACHIEVE Plan: (Gradual weight loss) Currently their $90 Off + Free Gifts promotion is the best deal. This includes free delivery on your first order

• Food Purchase:

If you are an existing customer or don’t want to commit to monthly “auto-delivery,” the best coupon will be one of the codes that give you $15-35 off your order. (*The $50 off $250 promo code is no longer available)

These codes change monthly, so please bookmark this page for the latest deals!


Remember, not every diet works for every person. If you are thinking of joining, first imagine whether the Medifast program will work for your specific needs, personality, and lifestyle. Medifast coupons aren’t of any value if the diet isn’t right for you!

If you still have questions, you can learn more about the diet in our review here, and be sure to check with your doctor before starting any weight loss program.

If you do join Medifast, congratulations! You’re about to start a journey to a healthier life. Just be sure to use one of our Medifast coupon codes or signup promotions to save up to $100+ on your order!
