Greetings, Doc. Nothing warms my heart like a health professional and/or academic who dares to question the Party Line on dietary advice. The continued preaching of the low-fat/high-carb theory long after it's been demonstrated as dubious makes me sick to my stomach. People are dying because of pharmaceutical and processed food industry interests.

You're correct to say that "one size does not fit all." There are many factors to take into account when it comes to trying to convince someone to change his/her lifestyle: religious beliefs, time and budget constraints, the resolve as Symphonyod mentioned... ultimately, the only plan that will work is the one the patient will stick with and be happy with. High drop out rate? Yes. There's nothing wrong with doing it in stages. If a doctor would have told me from day 1 that I'd need to go paleo, I probably never would have bothered. But the Protein Power (Drs Eades) "hedonist" plan was a little more up my alley.

It's a learning curve.

Welcome aboard.
