@gamblemaxxer People hate being told what to do.
Instead try telling them these things indirectly. "I stopped jacking off because the sexual frustration motivates and energizes me" or fasting as a religious thing. Tell 'em to cut off PUFAs because "repurposed machine oil is for poorfags." Be deliberately obtuse and abrasive and they won't be able to stop themselves from being fascinated.
This is because first and foremost, der normgroid has evolved to be beaten to near death over and over. His entire existence is calibrated to having a jackboot shatter the vertebrae in his neck and pulverize his teeth every day. They love being insulted and treated like subhuman morons!
