Adherence
Calorie reduction messaging is counterproductive and potentially harmful for individuals with food insecurity or eating disorders, as it can reinforce distorted logic, rationalize harmful behaviors, or ignore survival priorities.
Do not use generic calorie reduction campaigns for food-insecure communities or individuals with eating disorders. For food-insecure groups, focus on access and quality, not restriction. For those with eating disorders, such messages can be dangerous and should be excluded or carefully managed by mental health professionals.
If you’re talking about people who are literally starving saying eat less is not the right message... Well, I think that patients with an eating disorder may use this to rationalize their behavior.

More from this paper
- Generic public health messaging encouraging adults to 'eat less' or reduce caloric intake is ineffective and potentially harmful because it fails to provide actionable strategies, ignores complex social and environmental barriers, and can trigger negative psychological outcomes in vulnerable populations.Moderate
- Public health messaging should emphasize nutrient density and specific behavioral strategies (e.g., using smaller plates, adding vegetables) rather than abstract calorie reduction, as this approach is more actionable, culturally resonant, and less likely to induce deprivation.Moderate
