Can Weight Loss (and its benefits) be Maintained?

Overweight and obesity are strong risk factors for type 2 diabetes (T2D). Excess body weight is strongly associated with insulin resistance and hyperglycemia. Weight loss plays a central role in efforts to prevent or delay T2D. In persons with overweight or obesity improved glycemia is readily noticeable with weight loss. However the health benefits of weight loss may last only when the initial weight loss persists over the long term.

The Diabetes Prevention Program (DPP) was a randomized controlled trial (RCT) that ran from July 1996 to July 2001. The DPP compared the efficacy of intensive lifestyle intervention (ILS), metformin, and placebo in prevention of T2D in 3234 participants with elevated glucose levels and overweight or obesity. Its Outcomes Study (DPPOS) began in September 2002 and examined 2779 (88.5%) of the remaining DPP participants.

A recent study analyzed the data from the DPPOS with the primary objective to identify some predictors of long-term weight loss (LTWL). It compared the differences in LTWL maintenance in the original intervention group among those who achieved at least 5% weight loss at 1 year and examined the baseline factors that predicted maintenance of weight loss for up to 15 years.

Three key findings emerged:

  • Although twice as many participants in the ILS group versus the metformin group lost at least 5% of their weight in the first year, those who were originally assigned to metformin had greater success in maintaining LTWL.
  • Other independent characteristics of LTWL identified were a greater 1-year weight loss in all the groups; older age and the prior use of metformin in the metformin group; older age and absence of either diabetes or a family history of diabetes in the ILS group; and a lower baseline fasting plasma glucose in the placebo group.
  • Cumulative diabetes incidence rates over 15 years were lower among those who lost at least 5% of their weight in the first year.

I cannot say enough wonderful things about Dr Robert Ziltzer! He helped me reach my ideal weight and more importantly maintain it for over 2 years. He has also helped me keep my blood pressure exactly where my internist wanted it. Dr Ziltzer is not only exceptional in weight management but also a truly gifted internet’s. His knowledge, kindness, and dedication are remarkable. I am deeply grateful for his care and recommend him whole heartedly!

I really felt comfortable with Kristen at my initial appointment. Everyone at the center was caring and friendly, from Bianca, at the front desk, to Lily, who is the MA. Kristen listened to my frustrations and prior disappointments about what has not worked, and is confident that she can help me achieve my goals of weight loss. I am looking forward and excited to see the success I will attain.

I'd lost 20 pounds on my own and struggled to keep it off. I decided GLP-1 meds were the next step in losing more and keeping it off. I wanted a medical doctor supervised program and chose SWLC. I am so very glad I did! The team in Glendale is so supportive and kind; and when I feel discouraged, they pick me up with positive energy and input. They really do a great job with encouragement all the time. 6 weeks in I've lost 17 pounds, and am approaching weight loss with a very new perspective. Also knowing that when I reach my target goal, they'll be there through maintenance and beyond is encouraging as well. Good to not feel alone on this journey.
