Medifast is a comprehensive, professionally supervised, and clinically proven weight loss program that helps people lose weight faster and more efficiently than traditional diet plans.* Weight-Loss-Straight-Ahead-pic-300x213

Medifast's clinically proven results are based on the use of a structured meal plan. The Medifast Meals are nutritionally designed with a specific combination of proteins and carbohydrates that allows for successful weight loss, while preserving lean muscle.

The Medifast 5 & 1 Plan, our standard program, is medically designed to create a calorie deficit, allowing your body to burn fat for energy.

Medifast is an effective, healthy weight-loss program, especially when compared to other diets you’ve likely experienced without success. Think of Medifast as a lifestyle change, not just a short-term diet or weight-loss solution. Medifast is a portion- controlled, low-calorie weight-loss program that leads to faster weight loss than traditional diets. Medifast has specially tailored programs to meet the needs of seniors, teens, and people with diabetes or gout.

Medifast clients can expect to lose two to five pounds for the first two weeks and one to two pounds per week thereafter.* The scale isn’t the only test, so check other indicators such as your waistline measurement and how well your clothes are fitting you. Your results are dependent upon various factors such as your starting weight, targeted weight-loss goal, level of exercise, presence of medical conditions, use of medications, accuracy with diet compliance, etc. As with most diets, Medifast suggests that you consult with your physician prior to starting a weight-loss program.

Medifast has been clinically proven through a number of controlled studies. Since 1980, more than 20,000 doctors nationwide have recommended Medifast Programs and products to their patients and more than one million customers have safely used Medifast.*

Weight-Loss-Caricature-158x300No. Medifast meals do NOT contain any added herbal stimulants, ephedrine, or other ingredients that might be harmful to your body.

Our Essential 1: Calorie Burn product line contains caffeine. Each Essential 1: Calorie Burn contains 100 mg of caffeine and 90 mg of EGCG, a potent antioxidant found in green tea. This amount of caffeine is equal to one cup (8 ounces) of brewed coffee. By combining these 2 ingredients, clients can get an extra metabolism boost. Using Essential 1: Calorie Burn products is a lifestyle choice, so if you would rather not consume EGCG and additional caffeine, you may choose other Medifast products. In addition, Medifast offers a line of energy infusers which contain B vitamins and 50 mg of caffeine per serving.

Medifast won’t abandon you the way fad diets have in the past. The Medifast Transition and Maintenance Plans pick up where the Medifast Weight Loss Program ends, and they equip you with the knowledge to make the right decisions to ensure your long term success!*

FAQs on Obesity

The National Institutes of Health defined obesity in 1985, stating that any individual at 20% or more over his/her desirable weight is obese. The medical community has further defined the condition, identifying terms for its progressing severity. Beginning in the moderately obese category, the risk of mortality and other medical complications begins to rise.

The distribution of fat varies between males and females. A study of over one million men and women by the American Cancer Society found the following:

  • Obese males, regardless of smoking habits, have a higher mortality from cancer of the colon, rectum, and prostate. Excess fat in males is found mostly in the stomach area.
  • Obese females have a higher mortality from cancer of the gallbladder, biliary passages, breast (postmenopausal), uterus (including both cervix and endometrium), and ovaries. In the case of endometrial cancer, women with marked obesity showed the highest relative risk (5:4) for the obese versus the non-obese. In women, the excess fat is found mostly in the thigh or gluteal area.
  • Excess abdominal fat is related to disease more frequently than fat deposits in the thigh or gluteal areas.

Thought at one time to be a simple problem and easily solved, obesity is now recognized as a complex and often chronic condition. Disagreement and debate still prevail on almost every key issue concerning obesity. Although the basic cause of obesity is an imbalance between calorie intake and energy expenditure, why this imbalance occurs is not always clear. The tendency to gain excess weight varies from one person to another, even when food intake, physical activity, and lifestyle appear to be the same.
The underlying causes of obesity are multi-factorial in origin and include:

  • Increased caloric intake
  • High-fat diet
  • Physical inactivity
  • Reduced basal metabolic rate (BMR) – BMR is the energy required for basic bodily functions, e.g., breathing, pumping blood
  • Reduced dietary thermogenesis (DT) – DT is the calories burned in the digestion and absorption of food
  • Heredity (may affect BMR, number of fat cells, etc.)
  • Medical conditions/medical treatment, e.g., hypothyroidism, steroids. Less than 5% of all cases of obesity are caused by medical conditions or by treatments for medical disorders
  • Psychological problems


Being obese can seriously affect health and longevity. Obesity has been established as a major contributor to five of the ten leading causes of death in the United States:

  • Coronary heart disease
  • Certain cancers, e.g., breast, colon
  • Stroke
  • Diabetes mellitus
  • Atherosclerosis
  • (References for this FAQ: 1, 2)
  • Hypertension
  • Insulin resistance
  • Elevated total cholesterol and low-density lipoprotein levels (LDLs)
  • Reduced high-density lipoprotein levels (HDLs)
  • Elevated triglyceride levels
  • Gallbladder disease/gallstones
  • Digestive diseases
  • Sleep apnea
  • Gout
  • Osteoarthritis and degenerative joint disease of the hips and knees
  • Increased surgical risks
  • Various circulatory diseases; varicose veins
  • High-risk pregnancies
  • Decreased mobility

FAQs on Weight Loss


The medical benefits that have been reported with weight reduction during or after the use of a low-calorie diet include:

  • A reduction in systolic/diastolic blood pressure
  • An improvement in blood glucose levels
  • A decrease in total and LDL cholesterol levels
  • A reduction in triglyceride levels
  • An improvement in respiratory function and sleep apnea
  • A reduction or alleviation in pain associated with osteoarthritis or inflammation of the joints
  • A reduction or alleviation of lower back pain
  • Increased mobility

blood-pressure-picture-300x228Reducing fat in a diet will contribute to weight loss and halt the buildup of plaque and fatty deposits on arterial walls. The plaque that is already there will remain unless reduced by surgery or medications. But hypertension related to fatty deposits, both in circulation and the body, will be improved through weight loss.

The timid, introverted, and non-assertive individual who started our program gains greater self-esteem and self-worth as their external image improves. This also comes from their recognition of a goal achieved.

FAQs on Soy

Medifast uses Supro® brand soy protein, a high-quality complete protein derived from soybeans. Supro® is produced by DuPont’s Protein Technologies. DuPont has been conducting soy protein research for more than 30 years.

Not only is soy protein a source of high-quality protein, but it is also thought to play both a preventative and therapeutic role in the following:

  • Studies show naturally occurring isoflavones (such as those in Supro® brand soy protein) have increased the mineral content and density of bones, which may protect against the risk of bone fractures and osteoporosis.
  • Studies have indicated that a regular intake of soy foods may help to prevent hormone-related cancers such as breast cancer, prostate cancer, and colon cancer in certain populations.
  • Soy may help to lower LDL cholesterol (bad cholesterol) levels in the blood. Reductions in LDL cholesterol have been shown to help decrease the risk for heart disease.
  • Soy reduces triglyceride levels and increases HDL cholesterol levels (good cholesterol), which further reduces the risk of heart disease.
  • Soy isoflavones, which are a natural phytoestrogen source, may help reduce menopausal symptoms such as hot flashes or night sweats.
  • Soy is a complete protein, providing all of the essential amino acids.

FAQs on Exercising on Medifast

Exercise is a necessary part of losing weight, improving metabolism, and maintaining weight loss. Exercise also provides many health enhancing benefits such as improved flexibility and balance, blood pressure control, strength and endurance, Exercise-senior-couple-199x300
If you are not already exercising regularly when you start the Arizona Medifast Program, we recommend you wait two to three weeks (and check with your physician) before you begin an exercise program. Start an exercise program slowly, and gradually increase time spent on an activity (and intensity of the activity) as your body allows. Choose an activity that you can enjoy regularly. Most of our clients find walking is the easiest activity to incorporate into their day.

For an individual who has an exercise program in place prior to starting Medifast, we recommend cutting the intensity and duration of your exercise program in half for the first couple of weeks to allow your body to adjust to its new calorie level. As your body adjusts to this lower calorie level, you can increase time and intensity of your exercise plan. For the entire time that you are on the 5 & 1 Plan, we recommend limiting vigorous exercise to 45 minutes each day.

Listen to your body and only do what it allows. If you feel lightheaded or faint, stop your exercise and take a rest before you resume. Remember to drink fluids—fluid intake is important when you exercise. You may find that you need additional water on the days you exercise, especially if it is hot outside.

For more information and exercise tips, see the
Medifast Weight Control Centers Exercise Guide.


FAQs Regarding Diabetes


If you have type 2 diabetes (adult onset), you should be able to do Medifast. Consult your physician prior to starting any weight-loss program, including Medifast. We suggest you monitor your blood sugar readings once or twice a day as well as stay in close contact with your physician for instructions on making changes in your medications.
