I think it's more likely to be due to the energy it takes to break down food (meaning you have less free energy) that causes people to feel sluggish after a large meal.

It might be dependent on what was eaten. Of you eat a carb-heavy meal, and you are very insulin-responsive, then you can feel tired afterwards.

Try skipping carbs at lunch, stick with protein+fat, see if that makes a difference.

I don't personally have this problem, even with carb-heavy lunches, but thanks for the advice.
