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.
Now, the POMC neurons, make something called Alpha-MSH. Melanocyte-stimulating hormone, Alpha-Melanocyte-stimulating hormone. If you don't want to remember any of the other acronyms and terms I've talked about, this episode so far, do try and remember M-S-H, okay? Mouse Sam Hamster M-S-H okay? MSH reduces appetite and it's a powerful molecule, all right?
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.
And the arcuate nucleus has some really fascinating sets of neurons that release even more incredible molecules and chemicals into the blood. And these chemicals act as accelerators on feeding and appetite, or breaks.
There are two types of neurons within a particular area of your hypothalamus that are relevant here. There are the so-called POMC neurons, okay? Proopioid melanoortin neurons that tend to act as more of a break on appetite by way of another hormone called melanocyt stimulating hormone. And you have a class of neurons called the AGRP neurons. The AGRP neurons are the ones that stimulate feeding and they create a sort of anxiety or excitement about food.
