The frustrating part is when it comes from the health professionals you are paying.

I've been working with my HMO to reduce my blood pressure and even though they are not giving me grief about being on Atkins, they still try to spout that stuff at me.

Just this morning I was telling one that I'd been a butter milk eggs an cheese eater all my life and have never had cholesterol problems.
She even admitted that my blood work looks good. But then she admonishes me that sometime it takes years for the negative effects to show up. I reminded her that I was 56 and she got that startled doe in the headlights look.
