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.

Fat soldier

A soldier on the job usually has to pack around about 100 pounds of body armor and equipment. Packing around an extra 25 or 30 pounds of fat isn’t a good thing. Overweight soldiers and Marines have become a problem for the armed forces and a group of retired military leaders, fearing for their future supply of able-bodied recruits, have launched a campaign against childhood obesity.

To fat to fight

According to a report titled “Retreat is not an Option” released by the group Mission Readiness, there were more medical evacuations from Afghanistan and Iraq to Germany for stress fractures, serious sprains and other similar injuries than for combat wounds. Given a choice, most people would probably pick the former over the latter. But in the Army, if you’re too fat to fight, you put your buddies at risk.

Mission Readiness believes that because about 40 percent of the nation’s current crop of 17 to 24 year-olds are overweight or obese, the nation is at risk as well. They released their report to try and convince Republicans in Congress to end their attempts to roll back healthy eating standards set by the Obama administration for the National School Lunch Program.

Active duty obesity

The armed forces were instrumental in establishing the National School Lunch Program because during World War II about 40 percent of military conscripts showed up suffering from malnutrition. Ironically, the military may be a victim of its own success, as only one in four 17 to-24 year-olds today is eligible for service. Obesity is cited as the main reason.

After the U.S. let itself get mired in both Afghanistan and Iraq at the same time, the military became desperate for warm bodies. Those who would have been previously disqualified, including obese people, were welcomed with open arms. Over the last 15 years, the number of obese people on active duty has more than tripled.

Slim pickings

With U.S. involvement in the Middle East winding down, the armed forces have been ordered slim down the ranks—in terms of numbers—from 570,000 to 490,000 by 2017. Unless another war happens tomorrow, the first to go are being discharged due to obesity.

However, the military must still recruit about 190,000 men and women a year to remain viable. In the search for those who are fit enough to pack 100 pounds of gear into combat, the pickings are slim.

School nutrition politics

The school nutrition program up for Congressional reauthorization is a plan to restrict junk food and sugary drinks, improve the quality of menus, expand eligibility for free school meals, and improve nutrition education.

The Obama administration has also requested an additional $1 billion a year to fund school nutrition. The Senate version of the bill, if it ever hits the floor, would allow half that amount. The House has yet to address on the issue. Does anyone really expect it to?
