Men's reactions to receiving objective feedback on their weight, BMI and other health risk indicators.

Undertaking measurements and receiving information on health risk indicators, such as weight or BMI, within the context of behaviour change programmes can enhance motivation for behaviour change when communicated in an empathic and non-stigmatising way, and therefore should be considered as an integral part of interventions. However, providing feedback on health risk may be insufficient to prompt behaviour change in some people and may be detrimental to those with poor body image and/or lacking personal agency to adopt lifestyle changes. It is therefore imperative that adequate support and opportunities are made available when information on weight and disease risk are fed back within research or other settings.
