AI Summary
5 min read"People are not really sitting down to eat a meal. Very often we find ourselves eating something and doing something else." That observation from Lilian Cheung, a lecturer on nutrition and the director of mindfulness research and practice at Harvard University, captures the central problem this episode of Life Kit addresses: the habit of eating too fast, often while distracted. The episode offers a calm, practical guide to slowing down, grounded in the psychology of mindful eating and the physiology of digestion.
Why 20 Minutes Matters
The episode’s core physiological insight is simple: it takes about 20 minutes for your body to signal to your brain that you are full. This involves both your nervous system and your hormone system. When you eat too quickly, you bypass that signal, which leads to overeating and discomfort. Cheung notes that eating fast can also cause hiccups, heartburn, and even biting your tongue or cheek. The 20-minute rule is the anchor for the entire practice of mindful eating — not a rigid timer, but a guideline for pacing that allows your body to catch up with your brain.
