Nineteenth Century Atkins diet !

Some years later, John Rollo, a surgeon trained in Edinburgh, was the first to add the adjective
“mellitus” to diabetes, from the Latin word meaning “honey”. He also famously developed a diet
(the “animal diet”) [ 4 ] to treat diabetic patients, which became the standard treatment in the nineteenth century. It was a diet based on animal food since it was thought that sugar was formed
from vegetables in the stomach.
