John Rollo

John Rollo was a Scottish military surgeon known for his pioneering work in diabetes treatment in the late 18th century. In 1797, he reported notable success in treating a patient with type 2 diabetes by placing them on a meat-based diet, which contributed to the historical context of low-carbohydrate diets. His findings have been cited in discussions of dietary approaches to managing diabetes, laying the groundwork for future dietary interventions and the modern carnivore diet.
