A new breakthrough in obesity research allows you to lose fat while eating all you want

This is a significant development that brings hope to the one billion individuals with obesity worldwide. Researchers led by Director C. Justin LEE from the Center for Cognition and Sociality (CCS) within the Institute for Basic Science (IBS) have discovered new insights into the regulation of fat metabolism. The focus of their study lies within the star-shaped non-neuronal cells in the brain, known as 'astrocytes'. Furthermore, the group announced successful animal experiments using the newly developed drug 'KDS2010', which allowed the mice to successfully achieve weight loss without resorting to dietary restrictions.

Why haven't I heard of people on benzos losing lots of weight?

Do you intend this in the sense of "GABA plays a leading role in mediating the interaction between [hyperpalatable food / increased food availability / changing food nutrient composition / ...] and obesity" or "obesity is specifically caused by something impacting GABA, and not by the modern diet"?

@jacksonpolack That's a good point. I guess I'm not as much of a warrior for unicausal theories of the obesity epidemic as the Slime Mold Time Mold bloggers are, so I wouldn't go so far as to say that e.g. hyperpalatable food plays no role - but equally, I don't think it plays as big of a role as people seem to think. So I don't really mean either of those things - I mean something closer to "while a bunch of different things may impact GABA, GABA is at the nexus of all the most important causes of obesity" or "At the level of human physiology, GABA is the most important causal factor behind the obesity epidemic".

Hm, why do you think that, if you don't mind giving a summary?
