I'll have to ask him next visit to my psychic medium.

I know he seemed to follow it when I saw him as a patient in the 80s and 90s but no idea since as I don't have his personal medical history except for what was printed in that article.
More importantly, he made sure as his patient you followed his diet and maintained ketosis as he was aware of how bad carbs are to someone like me who showed early on that I was to become diabetic as having reactive hypoglycemia, hyperinsulinemia and problems with carbs since young. Last time I saw him alive he strongly admonished me for having eaten a nectarine before the visit, thus not showing ketones on testing.
Maybe Atkins, like me, experienced problems when aging. I can't lose the weight I used to and have to be even more strict with the diet due to advancing insulin resistance and overall miasmatic progression.
Whether he followed his diet or not is immaterial to what he accomplished and shouldn't be used as a reason to detract from that and dismiss it as a farce as the quackbuster does to homeopathy.
He brought early awareness of the harm of high carb diets, refined sugars, HFCS, grains and benefits of low carb dieting, ketogenic dieting and much research has been published on that.
As homeopaths, we promote best health practices as we know and believe but are not all saints and may have our own vices.
