Product & Plan FAQs

Essential1: Calorie Burn

What's in Essential1: Calorie Burn that makes it a metabolism booster?
Each serving of any Essential1: Calorie Burn product - Meals or Flavor Infusers? - contains 100 milligrams of caffeine and 90 milligrams of epigallocatechin gallate (EGCG), a potent antioxidant found in green tea. This combination helps recharge your energy and tame your appetite, while gently boosting your metabolism so you can burn more calories. When you enjoy Essential1: Calorie Burn products three times a day, you can burn up to 100 extra calories!
Do Essential1: Calorie Burn Flavor Infusers? have calories or carbohydrates?
Yes, each Flavor Infuser? contains 5 calories and 2 grams of carbohydrates (1 gram coming from fiber). There is no protein or fat in a Flavor InfuserTM. Essential1: Calorie Burn Flavor Infusers? are considered a "free" item, meaning we are not counting the carbohydrates because the thermogenic effect (or boost in metabolism) the product provides basically cancels out its calories.
Is Essential1: Calorie Burn a "sports" drink?
No, sports drinks are electrolyte replacements. Essential1: Calorie Burn is a "metabolism booster" or "metabolism booster" geared to weight loss and weight maintenance.
Is Essential1: Calorie Burn an "energy" drink?
In a way, but there's a difference: Most energy drinks will give you the "pick me up" feeling from caffeine alone, but Essential1: Calorie Burn also allows your body to burn additional calories because of it also contains ECGC to boost your metabolism.
What artificial sweetener is used in Essential1: Calorie Burn products?
Essential1: Calorie Burn Meals are sweetened with a combination of acesulfame potassium and fructose (a natural type of sugar found in foods like fruit) and Essential1: Calorie Burn and Flavor Infusers? are sweetened with sucralose, the main ingredient in Splenda.
Does Essential1: Calorie Burn decrease appetite?
Clinical studies conducted by Medifast researchers at Jason Pharmaceuticals found Essential1: Calorie Burn speeds metabolism and decreases appetite, but it does not contain a specific appetite suppressant.
Clinical studies claim Essential1: Calorie Burn provides a 24 percent boost in metabolism. What does that mean?
If you replace a regular soft drink (150 calories) with a serving of Essential1: Calorie Burn every day for one year, even with no change in exercise habits, you could theoretically lose up to 24 pounds.
Does Essential1: Calorie Burn have side effects?
Only those related to use of caffeine.
Is Essential1: Calorie Burn safe for people with diabetes?
Yes. All Medifast products are safe for people with type 2 diabetes!
Can I substitute Essential1: Calorie Burn for a cup of coffee to get my morning jolt?
Yes! Essential1: Calorie Burn contains about the same amount of caffeine that's in one 8 oz cup of coffee (100 milligrams).
Can't I just take 100 milligrams of caffeine and get the same benefit as Essential1: Calorie Burn?
No, Essential1: Calorie Burn's combination of caffeine and EGCG works synergistically to boost metabolism, inducing thermogenesis and helping you burn calories, unlike caffeine alone.
If I take Essential1: Calorie Burn at night/in the evening, will it disturb my sleep?
If you are currently able to consume caffeine at night with no problems, then you should be okay. If caffeine in the evening disrupts your sleep, limit your Essential1: Calorie Burn use to earlier in the day.
Can I use Essential1: Calorie Burn if I'm caffeine-sensitive?
Essential1: Calorie Burn contains caffeine, so respect your caffeine limits. You may wish to discuss this with your physician, especially if you have any ongoing health concerns or if you take medications. If your physician says to avoid or limit caffeine, follow his or her advice and do not use Essential1: Calorie Burn.
Who should not use Essential1: Calorie Burn?
You should not use Essential1: Calorie Burn if you are pregnant or nursing, under the age of 18, or have been advised by your physician to avoid or limit caffeine.
Can I use Essential1: Calorie Burn with other weight-loss products that have ephedra- like stimulants?
We do not recommend it. Combining any source of caffeine with ephedra products can be dangerous to your health.
What is EGCG? Isn't EGCG just another form of caffeine?
Epigallocatechin gallate (EGCG) is different from caffeine, and has its own health benefits. It is a potent natural antioxidant found in green tea (which contains caffeine in addition to ECGC).
Do you still have the regular (non-Essential1: Calorie Burn) versions of Cappuccino, Chai Latte, and Banana Creme Shake?
Yes!
How do Essential1: Calorie Burn Flavor Infusers? fit into my 5 & 1 Plan?
The 5 & 1 Plan allows you three caffeinated beverages (or approximately 300 milligrams of caffeine) each day during the weight-loss phase. One Flavor Infuser? is considered one caffeinated beverage (even if added to 16 oz of water) because it contains the same amount of caffeine as an 8-oz cup of coffee.
Will I lose more weight if I drink more than 3 Essential1: Calorie Burn products per day?
No. Three provide the maximum therapeutic benefit. Consuming more than three Essential1: Calorie Burn products daily will not have an additional effect on metabolism and is not recommended during the weight-loss phase. Three Essential1: Calorie Burn products is the best amount - and what we recommend.
Can I double-up on Essential1: Calorie Burn Meals or should these only be taken 2-3 hours apart?

We recommend that you take all Medifast Meals two to three hours apart, especially Essential1: Calorie Burn Meals because of the added caffeine.
