Good god no.

If I can change my behaviour and achieve good health outcomes, relatively painlessly, why on earth would I not?

This comes across to me like people who won't use painkillers - I should feel the pain, masking it is fake, there is virtue in suffering etc. Turns out those people often end up with secondary complications to (for example) muscle damage, because they've adapted their movements so much to avoid using the painful muscle that now everything else is tense, strained and locked up.

Better living through chemistry, 100%.
