Just start on semaglutides, and eat in smaller portions like the women critics he describes in the article do. I think quitting a good critic job for your health is pretty silly when there are modern workarounds that mostly solve the issue.
The author literally described how women food writers keep their health while writing food columns - they taste the dishes but don't eat the whole plate. He doesn't say this makes women worse food writers at all.
He could just copy this strategy. If he doesn't have the will for it, semaglutides would make it really easy. You still enjoy and taste food the same on it, you just get full quicker.
Complete indifference to food and water that led to fainting and probable heat stroke. Extreme nausea. All mitigated now with medication and forced hydration. Not fun.
