Dr. Robert Atkins, whose popular diet stresses protein-rich meat and cheese over carbohydrates, weighed 258 pounds at his death and had a history of heart disease, a newspaper reported Tuesday. Atkins died last April at age 72 after being injured in a fall on an icy street. Before his death, he had suffered a heart attack, congestive heart failure and hypertension, The Wall Street Journal reported, citing a report by the city medical examiner. Associated Press
