A fuel partitioning perspective on appetite suppression by GLP-1 receptor agonists
Appetite suppression by glucagon-like peptide-1 receptor agonists (GLP-1RAs) is thought to result from direct actions on neural circuits controlling food intake. In this article, we (1) propose that a shift in fuel partitioning toward fat oxidation caused by GLP-1RAs contributes to appetite suppression and (2) explore potential lines of research to test this hypothesis.

As the world focuses on its billion-plus obese citizens, there remain people at the other end of the spectrum who are skinny, often painfully so, but don’t want to be. This recent @knowablemag.bsky.social article explores the “real enigma” of a condition. knowablemagazine.org/content/arti...

The other end of the weight spectrum: Very thin people
Researchers are exploring why some individuals are naturally super-lean and may struggle to gain weight. The causes of such constitutional thinness offer clues to the physiology of weight control.

Inhibition of the hypothalamic ventromedial periventricular area activates a dynorphin pathway-dependent thermoregulatory inversion in rats
Morrison et al. show that the inhibition of ventromedial periventricular area (VMPeA) induces a state of thermoregulatory inversion (TI) in which thermogenic responses to cold ambient exposure are actively inhibited by an alternative thermoregulatory pathway via a dynorphinergic system. VMPeA is a switch for this novel thermoregulatory paradigm.
