Sleeping less than 6 hours? Doctor explains how poor sleep may make you gain weight

Sleeping less than 6 hours raises cortisol, which promotes abdominal fat storage and increases blood sugar.

Sleep deprivation disrupts appetite hormones, leading to intense cravings for foods that worsen insulin resistance.

Dr. Gagandeep Singh of Redial Clinic treats short sleep as a metabolic event, not just a lifestyle issue.

Weight gain can occur even with a calorie deficit and daily steps if sleep is insufficient.
