The Stillman diet is a high-protein, low-carbohydrate diet devised in 1967 by physician Irwin Maxwell Stillman (1896–1975). It focuses mostly on the complete avoidance of both fats and carbohydrates, and requires the consumption of at least eight glasses of water per day. The diet is very low in fiber, vitamins and minerals, and it eliminates the consumption of bread, fruit, sugar and alcohol.
