You CAN be a functioning cocaine addict too. On the whole being fat is unhealthy and I've also noticed the straw man this argument uses, which is to act like anorexic weight loss is the antithesis of choosing to be fat rather than a reversion to a body composition equilibrium. https://twitter.com/princessalaafia/status/1338646056700174339

There are absolutely unhealthy ways to lose weight and you can actually end up less healthy doing them, but there are no "healthy" ways to stay fat considering most people actually need to consume in excess in order to stay fat.

There is actually a positive message hidden here, which is "losing weight in an unhealthy way can be worse than being fat, so don't focus on the literal loss of weight as your goal." Don't turn this into identitarian bullshit.
