I understand what you’re trying to say here and I agree we should be careful prescribing lifestyle changes for serious cases of depression (or any disease for that matter). However, there are a significant number of people out there who _don’t_ have treatment resistant depression and would benefit from lifestyle interventions. I think it’s a good thing for research to be done in that area, and being dismissive of something helpful for many because it doesn’t help those with serious cases isn’t a particularly healthy place to start a conversation from.
