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.
But for instance, if there's a food that you want to consume more of, but that you find somewhat meh, or mildly yuh, yuck, even pairing it with ketones, if indeed, you are using ketones for your brain metabolism, 'cause that's what happens on the ketogenic diet, over time, that food will be reinforced by the dopamine pathway.
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.

So initially, we don't tend to like artificial sweeteners that much. That's the simple way of putting it. However, if subjects continue to ingest artificial sweeteners, even though there's no increase in blood glucose level, and therefore, no increase in brain metabolism, dopamine levels eventually start to rise. And when those dopamine levels eventually start to rise, you've essentially conditioned or reinforced that artificial or non-caloric sweetener, and then subjects start to consume more of it, and they actually get a dopamine increase from it.
When that happens, what you're essentially doing is tapping into the dopamine system. This non-coric sweet taste is paired with it and there's an increase in in neuron metabolism.
