OWINGS MILLS, Md., June 13 /PRNewswire-FirstCall/ -- Researchers from
Johns Hopkins Bloomberg School of Public Health released the results of an
86-week diabetic weight loss study that found participants using Medifast's
portion-controlled, meal replacement program lost twice as much weight and
were twice as likely to complete the study as participants following a
standard food diet based on the dietary guidelines of the American Diabetes
Association (ADA). Additionally, 24 percent of the Medifast users decreased
or eliminated their diabetes medication, compared to 0 percent on the standard
food diet.
The study, "Long-Term Efficacy of 2 Diet Plans for Type 2 Diabetes on
Weight Loss and Weight Maintenance," was officially presented by Johns Hopkins
Bloomberg School of Public Health Associate Professor Dr. Lawrence J. Cheskin,
M.D., during the American Diabetes Association's 65th Annual Scientific
Session in San Diego this past weekend.
Dr. Cheskin's study enlisted 112 overweight or obese people with type 2
diabetes using two weight loss approaches of equal caloric prescription - a
portion-controlled, supplement-based diet (Medifast) and a traditional
reduced-calorie diet based on the ADA's recommended dietary guidelines. The
study tracked the participants' progress over 86 weeks (approximately a year
and eight months), including an initial weight loss period of 34 weeks,
followed by a 52-week maintenance phase.
"Weight loss is critical for controlling type 2 diabetes, but individuals
with the disease are faced with health issues that make it significantly more
difficult to lose weight than people without the disease," explained Dr.
Cheskin. "While type 2 diabetes cannot be cured, losing weight can
significantly improve one's quality of life by reducing or even eliminating
the need for daily medication and/or frequent treatment. People with type 2
diabetes are in need of weight control options they can commit to long term."
According to the results, the Medifast group lost twice as much weight and
was twice as likely to complete the study as the group on the standard food
diet. Of patients completing the initial weight loss phase (34 weeks),
average weight loss was 16 pounds on Medifast and 8.1 pounds on the standard
diet. After completing the additional 52-week maintenance period, average
weight loss after 86 weeks was 13 pounds for those who received Medifast in
Maintenance vs. 5.3 pounds on the standard diet. Also, 44 percent of the
Medifast participants maintained more than a five percent body weight loss vs.
only 14 percent on the standard diet.
"There is no room for miscalculating portions when using portion-
controlled foods, which might explain in part why participants on Medifast
achieved superior weight loss results and demonstrated significantly better
completion rates," added Dr. Cheskin. "In addition, meal replacements are
easy to follow and require less effort, which is why they can be an effective
weight loss option for many people in serious need of losing weight."
A crucial finding was a significant drop in diabetes medication intake for
the Medifast group. After the 34-week weight loss phase, 24 percent of the
Medifast participants either decreased or eliminated their diabetes
medication. None of the participants on the standard food diet could say the
same.
"The difference in diabetes medication intake between the two diets
reflects that Medifast was significantly more effective at helping to control
type 2 diabetes than a standard food diet," explained Dr. Cheskin.
Brad MacDonald, CEO of Medifast, Inc., states, "This study reinforces the
fact that with Medifast, people not only lose weight, but their health
improves as well."
