When a calorie is not a calorie

Thanks to Dr. Michael Gregor of NutritionFacts.org

Dr. Gregor points out the benefit of consuming calories in the morning vs. later in the day or evening. I share this mostly in consideration of improving overall blood sugar management and preserving our precious insulin sensitivity:

  • Morning meals contribute to bulking up muscle glycogen reserves, requiring additional energy for the assembly and disassembly of glucose molecules into glycogen. This process may make morning meals less efficient in terms of calorie utilization. 
  • Muscles are more sensitive to insulin in the morning, efficiently pulling blood sugar to build glycogen reserves. In the evening, muscles become relatively insulin-resistant, leading to higher blood sugar and insulin spikes, potentially contributing to weight gain and poorer blood sugar control.
