Extreme temperatures drive people toward high-fat diets, study finds

Short-term exposure to extreme temperatures alters dietary patterns by increasing fat intake, even when total calorie consumption remains stable. This shift, driven by physiological appetite regulation, raises the risk of high-fat diets and diet-related diseases, especially among vulnerable groups.
