The Emerging Science of Being Hangry

German researchers tracked 90 adults for four weeks using glucose monitors and smartphone apps to understand the science behind being "hangry." They discovered that hunger-related mood changes depend on consciously sensing bodily signals rather than unconscious blood sugar drops, meaning it's how your brain interprets gut signals that matters. People with better interoception—the ability to read their own body's signals—experienced fewer mood swings, suggesting that improving this skill through mindfulness and breathing exercises could help prevent hangry episodes.
