Why dinner matters: Eating a large or high-carb dinner causes sugar to be stored in the liver. Overnight, your body releases this sugar gradually into the bloodstream to maintain blood sugar levels.
Impact of late-night snacks: Snacks close to bedtime can leave partially digested carbs that raise morning sugar.
The “dawn phenomenon”: Hormones like growth hormone and cortisol rise in the early morning, boosting blood sugar. If you ate heavily the night before, this effect is amplified.
Management tips:
Keep dinner moderate, with fewer carbs and more protein/vegetables
Avoid snacks 2–3 hours before bed
If fasting sugar is high, first review your evening meals
? Summary: Morning fasting blood sugar often reflects your dinner and night habits.
