Patients with obesity are working against their own physiology to maintain the weight they lost3
After weight loss:
metabolic adaptation leads to decreases in resting metabolic rate and increases in energy intake3,4
hunger and satiety hormones are triggered, decreasing satiety and increasing appetite3,5
Weight regain is not an issue of behavior alone4
A review of 14 long-term studies showed that people with obesity regained weight after weight loss achieved by dieting.1
Study participants’ weight and diet statuses were assessed at baseline; then their weight was measured at follow-ups for up to 7 years after the diet ended.1 These data are from a review of 14 diet studies with long-term follow-ups. Adapted from Mann T, Tomiyama AJ, Westling E, Lew AM, Samuels B, Chatman J. Medicare’s search for effective obesity treatments: diets are not the answer. Am Psychol. 2007;622(3):220-233.
“…the high rate of relapse among obese people who have lost weight has a strong physiological basis and is not simply the result of the voluntary resumption of old habits.”3
