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.

hourglass

Research shows people who are overweight or obese greatly increase their risk for cancer. According to the World Cancer Research Fund, about 20 percent of all cancers diagnosed in the U.S. are associated with excess body weight, physical inactivity, alcohol abuse and poor diets. Of all these factors, body weight has had the strongest correlation with cancer—about 1 out of 5 cancer deaths.

What’s more, a new study suggests cancer risk continues to increase the longer a person is overweight or obese. But it’s never to late in life to reduce your cancer risk by losing weight.

Obesity duration and cancer

Most of this research has found a link between obesity and cancer in cross-sectional studies—a type of research that compared the height and weight of people with incidence of cancer at a particular moment in time. However, in a report on their new study published in the journal PLOS Medicine, an international team of cancer researchers noted they are among the first to explore how the duration and degree of obesity affects cancer risk.

Using data from the United States Women’s Health Initiative, the researchers investigated about 74,000 postmenopausal women who were tracked for an average of 12.6 years. They found that for every ten years a woman spent being overweight, her risk for obesity related cancers increased 7 percent.

Inflammation, hormones

The types of cancer related to overweight and obesity include: Breast, Colorectal, Uterine, Kidney, Head and neck, Esophageal, Pancreatic, Endometrium (lining of the uterus), Prostate, Gallbladder, Thyroid.

Research to date has come up with several possible explanations for the link between body fatness and cancer. Chronic, low-level inflammation is common with people who are overweight and obese. Inflammatory compounds released by belly fat packed around vital organs are associated with a higher risk for colorectal cancer, as well as cancers of the pancreas, endometrium, and breast. Excess adipose (fat) tissue also effects the body’s release of insulin, insulin growth factor-1 and estrogen, which promote the development of certain cancers.

Lower cancer risk

The good news is that losing weight can reduce levels of the inflammatory compounds, insulin, estrogens and androgens elevated by overweight and obesity. Evidence exists that weight loss could reduce the risk of breast cancer, protate cancer and other cancers. Maintaining a healthy weight is also associated with lower cancer risk. However, yo-yo dieting—a cycle of losing and regaining weight—increases your risk.

Lowering your cancer risk doesn’t require a drastic amount of weight loss. It’s been proven that losing as little as 5 percent of your current weight can start making changes in your body that reduce your risk of cancer, as well as heart disease, diabetes.
