Inaccurate. When Dr. Atkins slipped on the ice and fell (an accident that could have happened to anyone, including a Neanderthal!), he was admitted to the hospital and at admission was weighed in at 195 lbs -- a healthy weight for his height (6-something).
While he languished in a coma with a fractured skill and other injuries, he suffered fluid swelling (edema), causing him to bloat up to about 260 lbs at his death. Various dishonest Atkins haters seized on this final figure as "proof" that he was ~65 lbs overweight at his death -- but in fact, he was fit and healthy until his accident.
