Frankly, a "solution" to a human problem that does not work with most humans, does not deserve to be called a solution.

Mental issues is a broad category as well. Are food cravings a "mental issue", or a "physiological/hormonal issue"? No clear difference between those two, and given how GLP-1s quench cravings in general - not just food cravings, plenty of people on those report losing their compulsive behaviors, even such as gambling or shopping - the hormonal variant sounds quite plausible.

Which may be actually good. We are a lot better in treating hormonal issues than mental issues.
