Study: Calorie Labels' Minor Impact on Intake

Recent research published in the Cochrane Database of Systematic Reviews shows that calorie labeling on food menus and products leads to a modest reduction in calorie consumption, averaging a 1.8% decrease, equivalent to about 11 fewer calories per 600-calorie meal. This decrease, while small, could have a meaningful impact on public health if maintained long-term, potentially preventing weight gain over a decade. The research analyzed data from over 10,000 participants across high-income countries like the USA, UK, and France, highlighting a consistent but limited effect of calorie labels. While calorie labeling is not a 'silver bullet' for weight management, it may contribute to broader public health strategies if combined with other measures like taxes and marketing restrictions. Concerns remain about potential negative impacts, such as effects on mental health and disordered eating, emphasizing the need for careful implementation.
