People say that they become sleepy after carb heavy meal.
I personally become sleepy after even low carb meals. Granted, I probably do not get enough sleep, but why is sleepiness related to food, without excess carbs?
Maybe we should try to emulate Europeans. I believe they eat dinner late in the evening and stay up later, then take a 2-hour siesta in the afternoon after lunch. Our bodies are supposedly not made to stay up for 16 hours straight and then sleep for 8 hours. That being said, I don't have afternoon sleepiness anymore since low-carbing. My energy seems to be spread out more evenly throughout the day and I sleep very soundly at night.
