Is there actually such a thing as feeling sluggish after eating, or any of those symptoms? I've never felt any of those, and I've eaten absolutely glutenous things before. Here is one of my recent glutenous breakfasts: Two cups of milk, "gain cakes" (cup of oats, 1 egg, some milk, 48 grams of nuts), and 6 fried eggs in olive oil. Aside from questioning the fuck I'd eat like that and having an excessively full stomach I felt fine. I've also eaten half of (a good) large pizza and felt fine afterwards. I don't eat absolute trash like Mcdonalds or most fast food places though.
