Do I have different calorie requirements in the winter?
Asked by soitwouldseem on Nov 12, 2010
Do I need more (or fewer) calories in the winter compared to what I ate in the warmer months? Does weather affect metabolism at all?
Your calorie requirements do not change significantly with the seasons. Shivering does increase the calories you burn during the time you actual spend shivering, but as long as you have heat and warm clothing to keep body temperature normal, you will not burn extra calories to generate heat. When people spend time outdoors in very cold weather, extra calories they may burn keeping warm are offset by the reduction of calories burned in activity, which is usually hampered by heavy clothing.
