This isn't even news really, but it's not adopted because getting sick people to exercise is more difficult and more expensive in practice than getting them to swallow a drug. So we stick with subpar treatments. Diet is also more effective than most drugs but giving everybody a good diet is arguably even more difficult than getting them all to exercise, given we only have so much supply of healthy foods available. I still hear an attitude that telling unhealthy people to exercise is condescending and neglectful because you aren't giving them "real medicine" meaning a drug, which I generally see as either grounded in sheer ignorance or one persons anecdotal experience. The amount of confidence I see in drugs that are effective in maybe 20% of the population, which is a lot of those used for mental health, is utterly bizarre.
