Nutrisystem have announced results of a small study carried out by the Temple University that suggests people with diabetes could lose up to 16 times more weight if they follow the Nutrisystem D.
NutriSystem Success D In A Nutshell
Nutrisystem Success D is described by Nutrisystem as “a new weight loss program formulated for the unique dietary needs of people with diabetes”.
All the Nutrisystem plans involve pre-packaged meals (ones with a long shelf-life or flash frozen Chef’s Table Entrees) that are formulated to be low-GI and to deliver a calorie-counted diet. The consumer is supposed to supplement these with fruits, vegetables and low-fat dairy products.
It’s free to join, but the cost of the pre-packaged meals average around $280 to $325 per month. The image above, taken from their website, shows one of these meals.
About the Study
The study followed 68 obese people with Type 2 diabetes for six months, putting half on the Nutrisystem D program and half on a standard hospital-directed diet and education program.
Nutrisystem’s promotional material states that:
According to the researchers, the study participants who followed the Nutrisystem D program lost on average 18 pounds during the initial 12 week assessment period and lowered their A1C test, by 0.9. By comparison, those who received the hospital-directed diet and education program over the initial 12 week period lost on average one pound, while their average A1C score increased by 0.03.
(The A1C test is intended to “give you a picture of your average blood glucose control for the past 2 to 3 months” – see American Diabetics Association: A1C test for more details.)
I’m inclined to be a little cautious about the results of this study. The number of participants was small (many medical studies involve hundreds or thousands of people). I couldn’t find the study on the official Temple University website.
The lead figure on the study, Dr Gary Foster, wrote the Nutrisystem Diet’s “Mindset Makeover” behavioral guide. Also, Nutrisystem provided an “educational grant” for the Obesity Management In Patients With Type 2 Diabetes dinner meeting at Temple University’s School of Medicine.
I may just be being suspicious, but all this suggests that the study may not have been carried out as rigorously as other medical trials.
If you do suffer from diabetes, consult your doctor before considering adopting a new dietary plan. If you’re thinking about Nutrisystem in general, see our review of Nutrisystem?
