It doesn't matter what time of the day or what food, about 20 minutes after I eat, I freeze. My aunt pointed it out to me about 20 years ago. We were driving across coutntry and she noticed that no matter what the temperature was (cool, warm, hot) when we would stop to eat I would be comfortable going in before the meal and about 15-20 minutes later I would be freezing. She said that she thought that was odd because food is fuel for your body and if anything, I should warm up after eating.
Here I am 20 years later (47) and to this day it happens after most meals.
PS Otherwise healthy.
No, not at all. Just very cold.
