Abstract: Improving the treatment of obesity remains a critical\n\n\n\nchallenge. Several health behaviour change models, often\n\n\n\nbased on a social-cognitive framework, have been used to\n\n\n\ndesign weight management interventions (Baranowski et\n\n\n\nal., 2003). However, most interventions have only produced\n\n\n\nmodest weight reductions (Wadden et al., 2002) and socialcognitive\n\n\n\nvariables have shown limited power to predict\n\n\n\nweight outcomes (Palmeira et al., 2007). Other predictors, and possibl alte nati e e planatory models, are needed to better understand the mechanisms by which weight loss\n\n\n\nand other obesity treatment-outcomes are brought about\n\n\n\n(Baranowski, 2006). Self-esteem is one of these possible\n\n\n\nmechanisms, because is commonly reported to change\n\n\n\nduring the treatment, although these changes are not\n\n\n\nnecessarily associated with weight loss (Blaine et al., 2007;\n\n\n\nMaciejewski et al., 2005). This possibility should be more\n\n\n\nevident if the program integrates regular exercise, as it\n\n\n\npromotes improvements in subjective well-being (Biddle &\n\n\n\nMutrie, 2001), with possible influences on long-term behavioral adherence (e.g. diet, exercise). Following the reciprocal effects model tenets (Marsh & Craven, 2006), we\n\n\n\nexpect that the influences between changes in weight, selfesteem\n\n\n\nand exercise to be reciprocal and might present one\n\n\n\nof the mechanisms by which obesity treatments can be\n\n\n\nimproved.
