Greetings dear readers. In an effort to better reflect our overall mission and upcoming strategic transition, we will soon be switching the name of our website. We will no longer be themedifastplan.com and will move to the new URL of DietScienceNews.com. We are hoping to have this transition completed in the upcoming days.

What does this mean to you? Nothing much to start with. We still love Medifast and will continue to promote what we view to be the most effective commercial diet on the market. However, you have probably noticed that we cover a lot of general diet and nutrition news in our blog posts. We are going to continue in this direction and develop a more agnostic approach to our views of the dieting industry.

We look forward to continuing this journey with you as we refine our quest for real, science based diet and nutrition news.


Americans are exercising more, but they aren’t getting much slimmer. Exercise is an essential part of a weight loss strategy, but portion control could be more important. The challenge is to maintain a balanced diet that provides the nutrition necessary to remain healthy while eating less.

Medifast Twice as Effective

When it comes to portion control, a recent trial found that the prepackaged food regimen featured with Medifast helped people lose twice as much weight compared with dieters who tried to match the same nutrition and calorie count on their own.

Exercise can’t overcome poor diet

A new study from the University of Washington’s Institute for Health Metrics found that in the last decade, the percentage of Americans who got sufficient weekly exercise increased from 46.7 to 51.3. In a report on the study published in the journal Population Health Metrics, the researchers concluded that this increased physical activity has done little to reduce the U.S. obesity rate.

According to the Centers for Disease Control and Prevention, more than a third of Americans are obese. A separate report by the institute published in the Journal of the American Medical Association identified poor diet as the primary reason why Americans are so unhealthy compared to other developed countries.

The portion control solution

Another study, published in the April 2013 issue of the International Journal of Obesity shows that a prepackaged portion control diet plan can be a viable solution to this intractable problem.

Researches at Tufts Medical Center in Boston conducted a rigorously controlled year-long study comparing the results of dieters on the Medifast 5 & 1 Plan with dieters given advice on how to achieve the same nutrition and calorie intake independently.

A total of 120 men and women from 19-65 years old with body mass indexes ranging from 35 to 50 were randomly assigned to two equally sized groups. The study included a 6-month weight loss phase and a 6-month weight maintenance phase.

Medifast results

At the end of the weight loss phase, people in the Medifast group lost an average of 16.5 pounds (6.7 percent of their starting weight). Those buying and preparing their own diets lost an average of 8.4 pounds (3.4 percent of their starting weight. The Medifast dieters shrank their waists an average of 2.24 inches compared to 1.46 inches for independent dieters. Total cholesterol dropped an average of 8.4 mg for the Medifast group compared to 1.1 mg for the independent group.

Often after a significant caloric restriction a few pounds return as the body seeks equilibrium and the Medifast plan was no exception. However, overall weight loss for the Medifast dieters was an average of 10 pounds, more than twice that of the independent group at 4.4 pounds.

The Medifast 5 & 1 Plan

The Medifast 5 & 1 Plan consists of five pre-packaged meals each day designed to supplement one meal of vegetables and protein prepared at home. The portion control program offers 70 prepackaged foods arranged in multiple combinations totaling 1,000 calories a day. Medifast dieters also receive access to dieticians and recipes for the home-cooked aspect of the plan, which costs about $300 a month.

The notion that if something is good for you, then more is better is often dismissed as flawed logic. This is true when scientific evidence fails to support consumption of mass quantities of certain vitamins, minerals and antioxidants in supplement form. However, new research suggests that when it comes to fruits and vegetables, believing more is better is eminently logical.

Double the dose

U.S. dietary guidelines have recommended including at least five servings of fruits and vegetables a day in your diet. A new study conducted by a team of scientists from the Norwegian University of Science and Technology and Imperial College London suggests that you double the dose to ensure a long and healthy life—and a healthy weight.

Their research, published in the International Journal of Epidemiology, represents the largest analysis undertaken on the relationship between eating fruits and vegetables and the risk of chronic diseases. They reviewed data from 95 different studies including several hundred thousand participants.

Risk reduction

Among the findings, each 200-gram (about 7 ounces) increase of daily fruit and vegetable consumption tended to lower risk of heart disease, stroke and premature death by 10.8 percent. The risk reduction persisted incrementally up to 800 grams (about 28 ounces) a day. At 28 ounces a day, you could expect to reduce your risk of heart disease by 24 percent, reduce your risk of stroke by 33 percent and reduce your risk of cancer by 13 percent.

Overall, you might reduce your risk of dying before your time from these diseases by 31 percent. Using those numbers, the researchers predicted what would happen if everyone in the world ate 28 ounces of fruits and vegetables a day. The results, however unlikely, would be a reduction in 7.8 million deaths. Those preventable deaths include two to four million from cardiovascular disease and 660,000 from cancer.

Most potent choices

The study also provided clarity on the specific types of fruits and vegetables associated with the greatest reduction in health risk. Fruits and vegetables rich in vitamin C such as apples, pears, citrus and leafy green vegetables were shown to be the most protective against cardiovascular disease and premature death.

In addition to vitamin C, these and other fruits and vegetables are rich in fiber, antioxidants, and potassium that contribute to good health in numerous ways.

Potassium is essential for controlling blood pressure and regulating a healthy heart. Increasing fiber intake has been shown to benefit blood vessel health by helping reduce cholesterol levels, blood pressure and inflammation. Fiber also helps protect against diabetes and obesity by slowing digestion to improve blood sugar levels and help you feel fuller longer after a meal.

Brightly colored fruits and vegetables are rich in antioxidants that help protect your body’s cells from free radicals, byproducts of metabolism that damage DNA, accelerate aging and trigger cancer.

How much is a serving?

How hard can it be to include up to 10 servings of fruits and vegetables into your diet? It helps to understand what an actual serving is. According to the Department of Agriculture, a serving is 1 cup of raw or cooked fruit or vegetables, or 2 cups of raw leafy greens.

In real life, a fruit serving can be a medium size apple or banana, half an avocado, two or three plums, apricots or kiwis, seven strawberries or 14 cherries. A vegetable serving can be ten baby carrots, five broccoli florets, an ear of corn, 7 cherry tomatoes or half a sweet potato.

Learning the truth about serving sizes shows us that our perception of a serving is often much larger than what experts consider healthy. The same is true with fruits and vegetables. A serving is actually much smaller than we may have thought, and that’s a good thing.
