The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

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.
But the impact on metabolism itself has been somewhat controversial because the overall changes in metabolism that are observed while statistically significant in many studies, have not ever really been shown to translate into weight loss or body fat loss in any kind of specific way.
but when one looks at the effects on metabolism they're pretty slight they are they're slight however studies like that to me always seem um shortsighted in the sense that if there's a longer Arc of effect on the mitochondria that's affecting other things in terms of how calories are processed or how calories are feeding into mitochondrial function or dysfunction there I could see how it might shift the um shift the scal so to speak
no I don't think it increases metabolism significantly enough to have a meaningful difference
