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.

As standards of living rise around the world, more people are adopting the standard Western diet of refined sugars, processed foods and beef. Agricultural and manufacturing processes supporting this diet are becoming recognized as unsustainable in regard to population growth and climate change.

However, a group of researchers predicts that universal adoption of a Mediterranean-type diet promises a brighter future for both human health and Planet Earth.

Climate change and food production

Although we take this fact for granted, the foods we eat depend on very specific climate conditions. Research of the effects of climate change on food production has found that increases in temperature and carbon dioxide can be good for crops in some parts of the world, and mostly bad for crops in other places.

One thing is for sure: climate change will disrupt ecosystems on land and at sea. If the human race doesn’t adapt, we could be in for some big trouble. On our present course, researchers from the University of Minnesota predict that by 2050, the food production required to support our diets could increase global greenhouse gas emissions 80 percent and destroy habitats in every corner of the planet.

Destined for disaster?

Recently the United Nations Intergovermental Panel on Climate Change warned that Global greenhouse gas emissions will need to drop by 40 to 70 percent by 2050 to prevent massive and irreversible changes to the Earth’s climate by the end of the century. That’s a tall order, but according to the UM scientists, changing our diets is one of the most important things we can do as individuals to control the damage.

In a report on their study in the journal Nature, the researchers analyzed global trends for consumption of meat protein, empty calories and total calories per person. If you think our diets are bad now, by 2050, they predicted humans will be eating even fewer fruits and vegetables, about 60 percent more empty calories and up to 50 percent more meat products.

The changes wrought should these trends continue not only included pandemics of diabetes, heart disease and cancer, but catastrophic increases in greenhouse gasses and widespread habitat and cropland destruction.

A dietary solution

After painting that dark scenario, the researchers projected the possible health and environmental impacts of adopting Mediterranean, pescatarian (fish as a protein source) and vegetarian diets around the world. Were that to happen, incidence of type 2 diabetes could drop about 25 percent, cancer rates could fall about 10 percent and heart disease deaths could be reduced about 10 percent.

What’s more, by adopting a plant-based diet, humans could prevent virtually all of the greenhouse gas emission increases and planetary destruction due to food production that otherwise lies in store if we follow our current diet trajectory.

Personal choice

It may seem unlikely for humans to make a species-wide change toward eating healthier in order to save the planet. But an awareness of the possibilities, both good and bad, that lie ahead could help people understand how the personal choices they make affect everyone.

Choosing what you eat could become one of the most important personal choices you will make.
