Energy balance
Increases in national food energy supply are sufficient to explain increases in average population body weight, particularly in high-income countries.
To combat rising obesity, focus on systemic changes to food supply and availability rather than just individual willpower. Governments and industries must improve food system healthiness.
GoodSupportsHIGH confidence
The findings suggest that increases in food energy supply are sufficient to explain increases in average population body weight, especially in high-income countries.
Why this rating
Large-scale observational study across 69 countries with statistically significant associations, though limited by ecological data and lack of individual-level intake measurement.
