Nutrisystem D Program Provides Proven Success According to Temple
University Researchers HORSHAM, Pa., Sept. 8 /PRNewswire-FirstCall/
-- -- Results from a clinical study conducted at the Temple
University School of Medicine and published today in the journal
Postgraduate Medicine(1), show that a pre-packaged, portion
controlled meal plan helped overweight individuals with type 2
diabetes lose significantly more weight and reduce their A1C test
scores (a 90-day measure of blood sugar control) by almost a full
point greater than those following a standard hospital-based
diabetes support and education program, according to the findings.
This weight loss was also associated with significant reductions in
blood pressure, cholesterol and waist circumference. The research
team, led by Dr. Gary Foster, Director of the Center for Obesity
Research and Education at Temple University School of Medicine,
followed 69 (49 F, 20 M) overweight people with type 2 diabetes, a
body-mass index of 39.0 +/- 6.2 kg/m2 and a hemoglobin A1C of 7.5
+/- 1.6%. Participants were randomly assigned to either a
portion-controlled diet (Nutrisystem D) or a diabetes support and
education program (DSE). In the study, the Nutrisystem D group lost
significantly more weight (8.2 +/- 5.2 kg compared to 0.6 +/- 2.6
kg) (p < .0001) and experienced greater reductions in A1C levels
(-0.88 +/- 1.10 versus 0.03 +/- 1.09; p < .001) compared to the
DSE group after three months. "Weight loss brings impressive
improvement in the control of diabetes," explains Dr. Foster, the
principal investigator of the study. "People with diabetes have to
perform mental gymnastics when they attempt to lose weight-
balancing carbohydrates, fats and proteins with overall calories,
all while keeping their blood sugar in check. The complexity can
cause many people to become frustrated and give up." "The
pre-packaged and portion controlled Nutrisystem D meal program
seems to alleviate some of those potential diet pitfalls for people
with diabetes by providing nutritionally-balanced and convenient
meals," continues Dr. Foster. "A structured plan empowers
overweight people with type 2 diabetes to transition from feeling
overwhelmed by meal planning to instead making healthy food choices
that can have a positive impact on both weight loss and blood sugar
control." The Diabetes - Diet Connection More than 23 million
Americans suffer from diabetes. Nearly all adults with diabetes are
overweight, and more than half are obese.(2) In research studies,
even modest weight loss (5-7% of total body weight) has been shown
to improve blood glucose, blood pressure, and cholesterol levels
and lower the risk of heart disease in overweight people with type
2 diabetes.(3) Other clinical studies have shown that weight loss
within the first three years of being diagnosed with diabetes, can
lead to long-lasting health benefits, even if the lost weight is
eventually regained.(4) Furthermore, the Center for Disease Control
and Prevention reports that in general, every percentage point drop
in A1C blood test results (e.g., 8.0% to 7.0%) can reduce the risk
of microvascular complications (eye, kidney and nerve damage) by
40%.(5) The American Diabetes Association (ADA) has emphasized the
need for structured programs that emphasize lifestyle changes,
including education, reduced fat and energy intake, regular
physical activity, and regular participant contact. Programs like
these can produce long-term weight loss of 5-7% of starting weight
and reduce the risk for developing diabetes, according to the
ADA.(6) Participants in the Temple University study were all
provided nutrition education, counseling and ongoing support in
group sessions led by a registered dietician and certified diabetes
educator. Topics covered in these education sessions included
self-monitoring, stimulus control and relapse management. All
participants were prescribed physical activity, such as walking.
"Our goal was to provide the same basic counseling that any person
with diabetes would typically receive, whether newly diagnosed or
living with the disease for many years," explains Dr. Foster. "In
each case, the addition of the structured diet program seemed to be
the catalyst for weight loss and improved blood sugar management."
Nutrisystem D Now Commercially Available The Nutrisystem D program
is now available for overweight people with type 2 diabetes. The
program includes 150 pre-packaged, portion controlled meals,
formulated using a low glycemic approach which emphasizes healthy
whole grains, as well as low fat and low sodium foods. The Glycemic
Index measures how quickly food is broken down and absorbed by the
body, which impacts blood sugar, a vital factor for people managing
their diabetes. A recent clinical study, published in the Journal
of the American Medical Association (JAMA) showed that for patients
with type 2 diabetes, 6-month treatment with a low-glycemic index
diet resulted in moderately lower HbA(1c) levels compared with a
high-cereal fiber diet.(7) Nutrisystem customers also receive a
welcome kit which includes a meal planner, a resource guide
highlighting Nutrisystem tips and tools for weight loss, and an
on-the-go meal planner. Nutrisystem recommends a combination of
diet and exercise to lose weight. Nutrisystem D is a comprehensive
weight loss program. It does not treat, cure or prevent diabetes,
and is not a substitute for diabetic medications. To learn more
