What this video covers
Take a moment to imagine your culinary kryptonite. That food when it’s placed out in front of you, you just can’t resist. For me as a kid, that was walnut dream bars from Rosie’s Bakery in Boston. If they were anywhere around, if we drove by a Rosie’s or if I got a whiff, I would hunt them down like a walnut dream bar assassin.

Key points, in the speaker’s own framing
- This paper, again published in the journal Science, one of the top journals in the world, is entitled GLP-1 increases pre-ingestive satiation via hypothalamic circuits in mice and humans.
- And what they found was really interesting, the humans given GLP-1 receptor agonists had greater satiation in particular during the pre-ingestion phase when provided with a food cue.
- So, humans provided with GLP-1 receptor agonists in general as a population have a greater pre-ingestion satiation, and this effect is actually much larger than during ingestion satiation.
- They then went on to show that this phenomenon was conserved in mice, that if you gave mice GLP-1 receptor agonists, they also had higher pre-ingestion satiation.
- So, what they did is they identified both in mice and humans there’s an area of the brain called the dorsal medial hypothalamus, which expresses GLP-1 receptor-containing neurons.
- So, the neurons have GLP-1 receptors, therefore, they might be mediating the effect of the GLP-1 receptor agonist.
