Brain's Weight Switch Found: May Let Us Eat What We Want, Finally (neurosciencenews.com)

A new discovery reveals that astrocytes, star-shaped cells in the brain, play a key role in regulating fat metabolism and obesity. These cells act on a cluster of neurons, known as the GABRA5 cluster, effectively acting as a “switch” for weight regulation.

The MAO-B enzyme in these astrocytes was identified as a target for obesity treatment, influencing GABA secretion and thus weight regulation.

KDS2010, a selective and reversible MAO-B inhibitor, successfully led to weight loss in obese mice without impacting their food intake, even while consuming a high-fat diet, and is now in Phase 1 clinical trials.

https://slimemoldtimemold.com/2021/07/11/a-chemical-hunger-part-ii-current-theories-of-obesity-are-inadequate/ is a good analysis of why calories in calories out is both true and not a good model for how weight gain/loss works in people.
