It is rather knee-jerk dismissive, true. Snarky? I'm not sure I have the evidence to claim that. They do have a good point, but the discussion is obviously more nuanced than that. People generally know that exercise is good for them, yet many/most people don't engage in it to a healthy degree. So some discussion of other approaches is appropriate. Let's not make "the perfect the enemy of the good" and all that. And we don't need to be either/or here. For individuals that have even a moderately elevated risk, doing both is probably a great idea (and of course this is already broadly recommended advice). Doing just one would still be better, and most people would choose a pill over exercise. Still a win in my book.
