Weight loss advice from a healthcare provider is motivating, but it is also stigmatizing: an experimental,...

It is standard practice for healthcare providers to give weight loss advice or counseling to higher-weight patients (ie, those with a BMI ≥ 30 kg/m2), but the immediate psychological consequences of this practice have rarely been examined.

We hypothesized that receiving weight loss advice from a healthcare provider might lead people to feel both motivated to engage in healthy behaviors and stigmatized for their weight.

Participants with higher weight (N = 294) were randomly assigned to read one of two doctor-patient interaction scenarios, and they were asked to imagine that they were the patient receiving advice. The scenario either involved the doctor giving behavioral weight loss advice (ie, standard diet and exercise recommendations) or control advice, which did not address weight or weight loss. Immediately after reading, participants reported their levels of behavioral motivation and weight-based identity threat.

Participants who received weight loss (versus control) advice reported significantly greater motivation for healthy eating and greater weight-based identity threat (Ps < .001, ds from 0.42 to 0.64). There were no significant group differences in perceptions of provider empathy or willingness to engage with the healthcare system in the future (Ps > .1, ds from 0.13 to 0.2).

As hypothesized, receiving weight loss advice made participants feel motivated to engage in healthy eating behavior, but it also made them feel stigmatized. These findings suggest that the standard practice of delivering weight loss advice should be reexamined, as it may harm higher-weight people and perpetuate inequity.
