Perhaps its the food they recommend that is the problem. When I'm on their recommended diet my cholesterol goes sky high and my blood pressure goes up - both markers for cardiac problems in their view.
Paleo - and those markers drop.
Nice to know too that I would be a screaming success with the loss of 25% of my weight with my first 13% of that in my first year, five years ago. Mind you I don't need their approval any more. Feeling healthy, becoming more flexible and fitter and having a nice wardrobe is reward enough.
