Product & Plan FAQs

Using Medifast Products

How often should I have my Medifast Meals?

Every 2 to 3 hours. It is important to start each day with a schedule, allotting specific times for eating your meals. Build 6 time slots for meals into your daily schedule and strive to be as consistent with this eating schedule as possible. If you know your schedule will shift a little (perhaps on weekends), make sure to shift your meal times accordingly.

We recommend that you eat your four Medifast Meals and two lean & green meals within a 24-hour period, regardless of what time your day starts. No matter when your day starts, try to have your first meal within an hour of waking, then eat another meal every two to three hours after that.

Eating every 2 to 3 hours helps to keep blood sugar levels more stable, ward off hunger, and keep metabolism active.

What happens if I miss a meal?

It is extremely important that you get in all four Medifast Meals and the full portions of your two lean & green meals each day. If you miss a meal, you may need to space the rest of your meals closer together to make sure you get the rest of your meals in before the end of the day.

Skipping meals will not help to increase your weight loss; in fact, it may have the opposite effect! If you have to decide between "skipping" a meal or "doubling up" to ensure you get in all four Medifast Meals and two lean & green meal within a 24-hour period, it is better to double up (eat two Medifast Meals at the same time) than to miss the nutrition provided by one of the Medifast Meals.

Should I take vitamins?

Generally speaking, you shouldn't need to take vitamin supplements while on the program. The Medifast Achieve Plan provides you with at least 100% of the daily value for 24 vitamins and minerals.

If you have been prescribed special supplements by your physician or have a specific concern, please consult with your physician so that they may adjust recommendation, as they deem appropriate.

If you and your physician choose to incorporate additional vitamin/mineral supplements, please be aware that the liquids, chewable, or powdered formulas often have added calories and carbohydrates which could hinder your ability to achieve the fat-burning state.

Can Medifast Meals be consumed after the best-if-used-by date?

Medifast powdered products have an 18-month best-if-used-by date. Medifast Ready-to-Drink Shakes and Bars have a 12-month best-if-used-by date. This does not mean that the product will expire, "go bad," or be harmful; it simply means that the vitamin and mineral pre-mix contained in the products may lose some of its potency, potentially rendering the product less effective. For best results, use your Medifast Meals as soon as possible and store them in a cool, dry, clean environment.

Can I mix two Medifast Meals together?

Yes. This can be a useful technique to get you through a challenging time if you are feeling hungry. Some Clients say this helps them to stay on the program successfully. Remember, however, it is most beneficial to spread your five Medifast Meals out throughout the day.

Can I mix my Medifast Meals ahead of time?

Medifast Meals are quick and easy to prepare whenever you're ready to eat them. You may choose to prepare certain Meals (such as the soups) ahead of time and store them in the refrigerator or a Thermos. We recommend preparing the Meal no more than a few hours before consumption and thoroughly mixing the Meal prior to eating to prevent any settling that may occur. Refrigerated pre-mixed items should be consumed within two days; non-refrigerated items should be consumed within four hours.

You might also be interested in Medifast Ready-to-Drink Shakes. These pre-mixed shakes are shelf-stable, can be stored easily and are interchangeable with your other Medifast Meals. Medifast Crunch Bars, Pretzel Sticks, and Cheese puffs are another great alternative for "on-the-go" lifestyles!

How much water should I drink on this program?
It is important to drink at least 64 ounces of water each day while on the Medifast Achieve Plan to keep your body hydrated.
What types of fluids are recommended?

We recommend plain water first. In addition to the recommended 64 ounces of water each day, you may drink any zero-calorie or calorie-free beverages, including unsweetened hot or iced tea, coffee or decaf, or diet sodas. You can also drink Crystal Light® and Sugar Free Kool-Aid® in moderation (see Condiment Options List). As a general rule, Medifast recommends that you try to drink as much fluid as needed for good health to keep your body hydrated.

Can I drink alcohol?

Alcoholic beverages are not recommended on the Medifast Plan. Alcohol provides unneeded calories, can slow your weight loss, tends to stimulates the appetite (encouraging additional food intake or lowering your resistance to outside temptations), and can deplete your body of needed water. Low-carbohydrate versions of beer and other types of alcohol are not recommended because these also provide calories with no nutritional value. Those who choose to drink alcohol tend to feel its effects at lower consumption levels, due to the lower calorie level of the Medifast Achieve Plan.

Can I use any seasonings or flavorings?

You can season your Medifast Meals and your lean & green meals with most herbs, seasonings, or spices. Experiment with different seasonings to find the flavors you enjoy. For general health purposes, we recommend limiting salt intake. Refer to our complete list of Condiment Options (PDF).

What are the limitations on the condiments I can use?

Some condiments are a significant source of additional calories and/or carbohydrates. Of course, we do want you to enjoy your food, but we recommend limiting condiment use in order to achieve the best weight-loss results and keep you in the fat-burning state. Refer to our complete list of Condiment Options (PDF).

What if I want to eat out at a restaurant?

Special occasion meals are easier to handle than you may think! Simply rearrange your Medifast Meal routine (if necessary) so that you can enjoy your lean & green meals at your breakfast meeting, family brunch, awards banquet, family dinner at a restaurant - or virtually any special occasion involving food!

You should have your typical lean & green meal serving of meat and vegetables as usual. Request that your meat be prepared/served without sauce sauces and/or added fats; switch out starchy vegetable options (like potatoes) for lower carbohydrate choices (like steamed broccoli or green beans). ). Ask your server to skip the breadbasket or bowl of chips, and always get dressings on the side if ordering a salad.

If you can't avoid eating something that isn't part of the lean & green meal, it may raise your daily calorie intake - but you can get back on the Achieve Plan starting with your next meal. It is still best not to skip meals, even when you think you may have over-eaten. Resume your plan as soon as you are able.

As an alternative, you can bring along a Medifast Meal and ask the waiter for hot or cold water (depending on what you are eating) to mix your Meal. Then simply prepare your Medifast Meal and eat it with everyone else!

How long can I stay on the Medifast Achieve Plan?

You may stay on the Medifast Achieve Plan until:

  • You've lost your desired amount of weight.
  • You develop a new contraindication to the program (such as pregnancy).
  • Your physician recommends you transition into our Thrive Healthy Living Maintenance Plan.

If you have significant weight to lose and plan to be on the weight-loss phase of the program longer than 16 weeks, we recommend that your physician monitor your program. After you've completed the weight-loss phase, you will transition into the Thrive Healthy Living Maintenance Plan.
