You're right in that he does recommend easing down the carbs more gradually for older people and those with compromised health, but what I read (in English, yes) was that once well into the diet, he determined that below 72g simply resulted in no additional benefits, not that it was harmful. If you can remember the specific reasons for not going below 72 I'd be interested. I can't read German.

What Bear doesn't realize is that he started eating zero carb when he was in his 20s. Dr. Lutz was treating people of all ages, but many much older who were already ill or had suffered permanent damage. I don't think Atkins thought of that either. I gather he used induction to jump start the body into fat metabolism (yeilding initially quick results and hence enthusiasm about the diet), not realizing that that might not be appropriate for older or more compromised individuals.
