Primum non nocere: obesity stigma and public health

Several recent anti-obesity campaigns appear to embrace stigmatization of obese individuals as a public health strategy. These approaches seem to be based on the fundamental assumptions that (1) obesity is largely under an individual's control and (2) stigmatizing obese individuals will motivate them to change their behavior and will also result in successful behavior change. The empirical evidence does not support these assumptions: Although body weight is, to some degree, under individuals' personal control, there are a range of biopsychosocial barriers that make weight regulation difficult. Furthermore, there is accumulating evidence that stigmatizing obese individuals decreases their motivation to diet, exercise, and lose weight. Public health campaigns should focus on facilitating behavioral change, rather than stigmatizing obese people, and should be grounded in the available empirical evidence. Fundamentally, these campaigns should, first, do no harm.
