The Banting diet is a high-fat, low-carbohydrate eating plan that was first proposed in the 1860s by a British undertaker named William Banting. The diet promotes the use of fat stores as fuel and restricts carbohydrates, including bread, beans, butter, milk, sugar, beer, and potatoes. The original Banting diet included four daily meals, which mainly comprised protein and restricted carbs, plus one piece of fruit as a snack or pudding. The updated version of the diet, known as Banting 2.0, was documented by a South African scientist, Tim Noakes, in a book titled the Real Meal Revolution. The diet includes four stages that follow a specific order, starting with observation and ending with maintenance. The Banting diet is a type of low carb, high fat (LCHF) diet that mostly restricts starchy, processed, and sugary foods, instead promoting the intake of wholesome ones to lose weight rapidly. However, following a diet that restricts food groups can make compliance challenging, and it may not be suitable for vegetarians or vegans. The Banting diet is not recommended for people with certain medical conditions, such as kidney disease, liver disease, or pancreatic conditions.
