The problem with most of the article I have read about high fat diet such as
Atkins is they never do a comparison of fat on the body to muscle mass
ratio. They only say people on a low carb diet loses more weight then other
diets, but how much of this weight is really fat loss not just water  and
muscle loss. I would love to see some real research on comparing apples to
apples for a change. It makes little difference what the scales say if this
weight loss in not mostly fat loss.

Good point (re sat fat).  Everything I've read says that unsaturated
fats are superior.  "South Beach" rather than Atkins.  The
Mediterranean diet with olive oil as its chief fat is well accepted to
reduce heart disease and be healthy.  I'm surprised that the Mayo
Clinic would test a high saturated fat diet.
