For what it's worth, my wife appears to be one of those. She does fine on the Anchell diet with liberal (i.e., almost daily) use of potatoes, so that her carbs are in the range of 60-70g/day. When she has tried cutting down to 30g the results have been poor: mood deterioration, persistent fatigue, headaches. And she doesn't seem to adapt after a week or so; if anything, it gets worse. I don't know if any of this indicates a slowdown of metabolism, but I do think that as her mood sinks she loses interest in eating, and eventually she would not be getting enough food to sustain her metabolism. For what it's worth, Dr. Lutz (the Life Without Bread dude) thinks that there are no advantages to reducing carbs below 72g/day. Although that wouldn't be ketogenic for sedentary people, it could easily be ketogenic for a person with an aggressive exercise program. Todd Moody [log in to unmask]
