This is a very interesting and insightful post, @BrianL. I like your measured/thoughtful (and non-pushy) approach, which is in the leadership style of example-setting and encouraging others if they express interest in following. Pulling others through example is always more effective than pushing against their inertia or lack of interest or receptivity.
Your post reminded me of my experiences when I discuss the ketogenic lifestyle. Let’s call them Approaches A and B:
APPROACH A:
Them: “Wow, you’ve lost weight!”
Me: “Thanks!”
Them: “How’d you do it?”
Me: “I’ve been eating a low carb, high and healthy fat diet with alot of emphasis on meats, non-starchy vegetables. Also, I fast every now and then for periods of 20 to 48 hours.”
Them: “Oh. That sounds really unhealthy!”
APPROACH B:
Them: “Wow, you’ve lost weight!”
Me: “Thanks!”
Them: “How’d you do it?”
Me: “I’ve cut out all sugars and refined packaged products, and have been trying to keep my carbs as low as I’m able to. I also don’t eat when I’m not hungry, which, on this way of eating, is pretty common (i.e., not hungry).”
Them: “Cool! Great work!”
It’s amazing how that different approach (by focusing on what I eliminated versus what I actually eat) has such a difference in their perceptions and reactions.
