Low carb is what we have evolved eating, our hormonal systems are adapted to it, our bodies are happy with it. There's nothing artificial about ketosis, it is the primary mechanism for energy utilization.

If you were generating significant cortisol when you was heavily into ketosis, wouldn't you think it would affect your mood? you would FEEL stressed. Ketosis has no such effect. The only person who seems to be stressed about ketosis, is apparently Dr. Schwarzbein.

This is not about Atkins/Eades versus Schwarzbein either. Keep in mind, low carb was first written about in modern times by Banting over 100 years ago. It was successful then, and has been successful since. It simply continually falls out of favor because it is not intuitively obvious (eat fat to lose fat?!). That and grain can be produced cheaply, so marketers of products have every incentive to lure customers into eating their crud.

In several years, Schwarzbein will be retired and living the good life on the money made from her little dietary niche.

When it comes down to it (fears of ketosis aside), what Dr. Schwarzbein suggests isn't terribly different from what many other low carb authors suggest: eat to your carb tolerance level.
The primary difference is where these different authors feel that level should be.
Dr. Schwarzbein is more specialized towards endocrinology, specifically for females. Women in general tend towards more hormone problems than men.
Do I think that just being in ketosis spells doom for a diet? Nope.
Dr. Atkins never intended for those following his plan to remain in ketosis for ever and ever amen, but he also felt that there was nothing inherently harmful in that if someone chose to do so. I tend to agree primarily based on what Tom had to say above.
