A new report combining perspectives from a range of obesity experts identifies genetic, epigenetic and neuro-hormonal differences between individuals as one of the key challenges associated with weight loss and long-term weight control. The authors, led by Paul MacLean, PhD, and Rena Wing, PhD, reinforce that maintaining weight loss over the long term can be a major challenge. They recommend a number of novel approaches to improve obesity therapeutics, including more emphasis on an individualized approach to weight-loss treatments and maintenance, and the integration of physiology and behavioral psychology to identify effective and sustainable interventions.
“Despite advancements in our understanding of obesity, weight regain after weight loss remains the most substantial problem in obesity treatment — with both the body and the mind conspiring against individual efforts to maintain weight loss,” said Dr. MacLean, co-chair of the National Institutes of Health (NIH) working group who authored the report, “Innovative Research to Improve Maintenance of Weight Loss,” published in the January 2015 issue of the journal Obesity. “There are many differences in individuals ranging from genetic to behavioral that lead some to do well on one approach, whereas others do not. Therefore, what works for a friend or coworker may be very different from a weight-loss program that’s most effective and sustainable for you over the long term.”
The NIH Working Group report summarizes the results from a recent conference and includes various perspectives from experts in integrative physiology, genetics, endocrinology, and behavioral and cognitive sciences.
The report is accompanied by a commentary in Obesity by research and treatment pioneers and TOS past presidents, George Bray, MD, of Pennington Biomedical Research Center and Thomas Wadden, PhD, of the University of Pennsylvania. In their commentary, Drs. Bray and Wadden called individualized weight-loss strategies “promising,” highlighting it as the most important issue identified by the working group to bridge the divide between basic and clinical sciences and better target obesity treatments.
“In all weight loss trials, whether behavioral, dietary, exercise or pharmacological, some individuals lose a great deal of weight, others an average amount, and some even gain weight,” they say in their response.
Drs. Bray and Wadden go further to call the area of personalized treatment an “essential focus” that should be combined with political and societal actions to change our food and activity environments, which currently exacerbate the struggle for most people who are trying to lose weight and keep it off.
“Personalized medicine is not a new idea; it is one that is applied and encouraged across many areas of medicine. Why not apply it to obesity treatment?” said Chris Ochner, PhD, TOS Public Affairs co-chair and Assistant Professor of Pediatrics and Psychiatry at the Icahn School of Medicine at Mount Sinai. “Weight loss is not a sprint; it’s a marathon.”
Working group co-chair Dr. Wing also stresses that current treatment approaches to improving maintenance of weight
