Cultural insularity, defined as the greater role of cultural identity in food choices, is positively associated with higher BMI in French populations.

If you live in a culture where food is central to identity, weight management may feel like a betrayal of your community. Recognize that 'cultural insularity'—letting cultural norms dictate food choices—is a real, measurable factor linked to higher BMI. To manage weight, focus on integrating health into your culture (e.g., modifying traditional dishes) rather than rejecting your heritage, as this reduces the psychological resistance to change.

In France, the cultural insularity score was higher than in the US (P = 0.01) and was correlated with BMI (r = 0.5, P = 0.03).
