Boo doesn't get annoyed or threatened so don't worry. I was just responding to what I thought your points were.
Lactic Acid Respiration... I don't know much about it, but the last time I heard that was on a 17 Y/O kid that had a heart attack while playing football. He was out of shape due to an illness and tried to keep up with his teammates. You have to really push yourself hard to start LAR.
Muscle mass and Atkins.

Doesn't ketosis lead to loss of muscle mass?
The notion that the Atkins Nutritional ApproachTM—high in protein, which builds muscle, and fat, which is used for energy—will force your body to break down muscle is incorrect. Only individuals on very low-calorie diets can lose muscle mass, because they have an inadequate protein intake. Atkins, however, is not calorie restricted (this isn't an invitation for gorging, but a recommendation to eat until you are no longer hungry) and the high protein intake required offsets any possible loss of body mass.
I also noticed a few people posting that their weights were steady on Atkins but they were losing inches. I believe from reading their notes that they are actually losing fat and gaining muscle due to their workouts. Muscle weighs more.
IMO - If I need to take a little health risk to gain a large health benefit it is worth it. So if I diet for 8 weeks in a year and (eat a healthy diet the rest) and lose 34 pounds that were stressing my heart then it is better for my overall health in the long run.
If you know anyone that is doing or thinking of doing Atkins please make sure they are informed on it. There are waaaay too many completely newbie questions being asked at Atkins Friends forums.
