The Zone diet was developed by Barry Sears, a biochemist from MIT, who popularized it in his 1995 book.
This diet aims to help with weight, inflammation and general health. It encourages that each meal be made of approximately 40% carbohydrate, 30% protein and 30% fat. This is the ideal nutrient ratio called the Zone.
Few foods are absolutely restricted. Foods that are avoided include food high in saturated fats like full fat dairy, egg yolks and fatty red meat. Refined and glycemic carbohydrates, starchy produce like root vegetables, juices and sugary fruits should also be restricted. This diet also reduces caffeine and alcohol.
There is a food quantity restriction based on a calculation for an individual’s daily protein requirement.
