Adherence
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.
Stop telling people to 'eat less' or count calories, as this induces fear and confusion. Instead, provide specific, actionable instructions on how to increase nutrient-dense foods (like vegetables) to naturally crowd out calorie-dense options. Use trusted sources like healthcare providers to deliver these clear, behavior-based messages.
Many experts identified 3 barriers that could impede the success of a public health messaging campaign to reduce caloric intake: (1) the complex social, environmental, and cultural factors that influence intake; (2) lack of actionable strategies to effectively reduce calories; and (3) the existence of too many, often conflicting, messages.
Why this rating
Based on qualitative expert interviews (n=60) rather than quantitative outcome data; high expert credibility but lacks statistical generalizability.

More from this paper
- 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.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
