📋 Short Answer
No. Total daily calories matter, not timing. Carbs at night may actually improve sleep and next-day workout performance.
The Full Story
The "carbs at night = fat storage" myth is based on the idea that insulin sensitivity is lower at night. Reality: insulin sensitivity varies more by individual than time of day. Some studies show carbs at DINNER improve sleep onset (carbs → tryptophan → serotonin → melatonin pathway). Carbs at night also fuel morning workouts (glycogen stores). What ACTUALLY matters: total daily calorie balance, not when you eat carbs. Some people sleep better with carbs at dinner. Others feel bloated. Experiment — check your sleep quality and morning energy, not the clock.
