"A starting point to determine the patient populations for whom dieting should be approved is examining the exclusion criteria for the original trials. Adherence to dieting is the most consistent predictor of weight loss and changes in health outcomes (Pagoto and Appelhans, 2013), and as noted above, non-adherent individuals are often excluded from trials. Despite the importance of adherence, dieting interventions are not evaluated based on whether participants are able to adhere to the regimen. "
[Show abstract][Hide abstract] ABSTRACT: Behavioral treatments for obesity are not evaluated by the same criteria as pharmaceutical drugs, even though treatments such as low-calorie dieting are widely prescribed, require patients' time and investment, and may have risks. The Food and Drug Administration (FDA) has a procedure for evaluating drugs, in which drugmakers must answer the following questions: (1) Is the treatment safe? (2) How dangerous is the condition the intervention is treating? (3) Is the treatment effective? (4) Is the treatment safe and effective for large numbers of people? We argue that using this framework to evaluate behavioral interventions could help identify unanswered research questions on their efficacy and effectiveness, and we use the example of low-calorie dieting to illustrate how FDA criteria might be applied in the context of behavioral medicine.

[Show abstract][Hide abstract] ABSTRACT: Macchi and colleagues propose a theoretical model that merges concepts from the biopsychosocial model and family systems theory to produce a broader framework for understanding weight loss and maintenance (see record 2013-28564-001). The Shifting Processes Model views individual weight loss and maintenance in the context of family dynamics, including family eating and exercise habits, home environment, and family relationships. The authors reason that traditional models put the burden of change on the individual rather than the family system, when the latter is an important context of individual behavior.
