Nighttime meals disrupt hormones, sleep, and weight, nutritionist says

A nutritionist explains that regularly eating large meals close to bedtime can disrupt the circadian rhythm, impair insulin sensitivity, and reduce sleep quality, potentially complicating long‑term weight management. However, outcomes depend on total calories, food quality, sleep, stress, and activity, so a sustainable approach is to eat a balanced dinner a few hours before bed and avoid fear‑based rules.
