I read it, and I think you're giving the best, SANE advice I've heard in a long time! Extremism in anything; a sport, a relationship, politics, or even a career, is usually a recipe for failure. In other words, "all or nothing" ultimately = nothing. I've been working out 30 years (with a few off-periods), and I've never been obsessed with my diet or gym time to the point where it would burn me out. I go by exactly what you said in so many words; "Moderation in all things". If being age 46 and still feeling 19, and 185 lbs with 4.9% body fat and a sharp 6-pack isn't proof that it works this way, then I don't know what is....
