Just 80 Minutes Less Sleep Each Night Linked to Weight Gain, New Study Finds
A six‑week analysis cited in Annals of Internal Medicine shows that cutting about 80 minutes of sleep per night can cause roughly 0.45 kg (1 lb) weight gain, larger waistlines, and more sedentary behavior—even with a healthy diet and exercise. Dr. Sudhir Kumar emphasizes that sleep is a third pillar of weight management alongside diet and exercise, and most adults should aim for seven to nine hours of quality sleep nightly to protect metabolism, heart, and brain.
