The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
Of course, ingesting large amounts of any kind of food, any substance that fills your gut will divert blood to your gut. So if you eat a lot of food regardless of whether or not it's a lot of carbohydrate or not, you're going to generally feel more sleepy.
If you eat a large volume of anything, because it diverts blood to your gut, you will feel lethargic and you will have less blood going to your brain.
And so I do want to point out that if you fill your gut with food, no matter what that food is, there's going to be a diversion of blood to your gut that's going to make you feel sleepy because there's a diversion of blood away from other tissues.
If we eat a lot of anything, whether or not it's ribeye steaks, rice, or cardboard-- please don't eat cardboard-- your stomach, if it's very distended, will draw a lot of blood into your gut. And you will divert blood from other tissues. And you'll become sleepy.
If you eat a large volume of anything, because it diverts blood to your gut, you will feel lethargic and you will have less blood going to your brain.
