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.

happy food

How aware are you of your emotions? Even though emotions play a critical role in the decisions people make, most are unaware of how their feelings are constantly working in the background to influence life. New research suggests that if you are serious about losing weight, taking an emotional inventory of your food feelings could help ensure your success.

Emotional eating

Many people who find they have become overweight are emotional eaters. Do you reward yourself with food? Do you eat when you feel stressed, or to cope with sadness, madness, anxiety or boredom? Do you feel out of control around food and eat even if you’re not hungry or if you feel full? If you can answer yes to any of these questions, your emotions could be overriding your physical need for food.

Emotional eaters focus their mental energy on food to distract themselves from what they are feeling or to prevent themselves from facing their feelings. According to a team of researchers from Ohio State University, Florida International University and the University of Kentucky, teaching people to be more emotionally aware is one of the most powerful elements of an overall weight loss strategy.

Emotional awareness

Their claim is based on evidence from their new study, published in the Journal of Marketing Research, in which they trained 170 volunteers who scored low on emotional stability scores in a pre-screening survey.

The researchers used small group discussions to address perceiving, facilitating, understanding and managing emotion. Training focused on food choices, as well as the big picture, including financial decisions and interacting with salespeople and fellow consumers.

Compared to a group of students who received no training, those in the trained group were more likely to make a healthy choice instead of selecting a chocolate bar when asked to choose a snack. Three months later when both groups were weighed, the training seemed to hold. Students who were trained to recognize their emotions lost weight, while the others actually gained weight.

Physical vs. emotional hunger

In additional to emotional awareness, recognizing the difference between emotional hunger and physical hunger can help you win the battle of willpower. While physical hunger gradually increases in intensity, emotional hunger is an acute, urgent sensation. Emotional hunger causes cravings for a specific food, depending on the emotion, i.e., pizza when you’re happy, or ice cream when you’re sad. Physical hunger can be satisfied by a variety of foods.

The Broccoli Test

When you find yourself in an emotional eating situation, consider giving yourself “The Broccoli Test.” If you really want to eat the broccoli, you’re really hungry. If not, the hunger you feel is emotional rather than physical. The Broccoli Test could help you resist indulging and avoid the guilt you would probably feel afterwards. That is, unless you really can’t resist broccoli. If that’s the case, eat it anyway. Everybody should eat more broccoli.
