Oh. Just to be a little more specific, when Atkins was admitted to the hospital, he was about 6’ tall, about 195 lbs. and in his 70s. The group that put out the description you cite was a Vegan group.
Atkins was tall and broad. He wasn't "fat" let alone "grossly obese." And, he did NOT have heart disease. He WAS, however, a practicing cardiologist, who discovered that his patients got WELL on a low-carbohydrate diet.
He died of head injuries sustained when he slipped on winter ice outside his New York offce. I'm very sorry to disappoint those vegans, but they will have to come up with a different dead horse to beat.
