Loss aversion has been used to explain many inconsistencies in traditional economic choice models, including anomalous patterns of choice under conditions of uncertainty.30,31 Critical to using loss aversion to motivate behavior is the concept of decision isolation; people react so powerfully to small losses and gains in part because they consider them in isolation and fail to integrate them psychologically with the often much larger fluctuations in income arising from work-earnings and investments.32,33, An important outstanding question is the relative cost-effectiveness of different approaches to achieving sustained weight loss, because maintenance of successful weight loss has been a big challenge in all weight loss programs.34,35 This has taken on increasing urgency because of markedly increasing rates of obesity within the US population.2,36,37 Many behavioral interventions and pharmacotherapy are costly and generally have produced weight loss in studies of 6 to 12 month's follow-up of only 3 kg to 5 kg.34 Surgical treatment, while effective in inducing weight loss in morbidly obese participants, has a relatively high rate of complications and high costs.38.  et al.
