The Zone Diet is a weight loss regime designed by Dr. Barry Sears. Zone Diet was popularized through the book “Enter the Zone” in 1995, which was written by Dr. Sears. In Zone diet, it is suggested that the individual should obtain energy from Carbohydrate, Protein, and Fat in the ratio of 40:30:30 respectively at each meal. This helps the individual to reduce weight. Studies have shown that people on Zone Diet not only lost weight, but gained muscle mass and they experienced less fatigue and other adverse effects associated with weight loss regime. It is also very effective for individuals with type 2 diabetes. However Zone Diet is harmful for infants, children, adolescents, and pregnant and lactating women. Zone diet is not beneficial for athletes.
Manuel Uribe of Mexico who weighed around 597 kg was considered as heaviest man in medical history and by Guinness Book in 2006. By October 2008, he lost several pounds with the help of Zone Diet and even got married on 26th October with his longtime girlfriend Claudia Solis.
Zone Diet includes foods like fresh vegetables and fruits, nuts, leafy green vegetables, sufficient amount protein, and eight glasses of water everyday. Not like other weight loss regimes, Zone Diet does not restrict calories intentionally. Instead the total amount of food eaten per day is based on the individual’s protein requirements determined by the dieter’s body weight, percentage of lean body mass, and level of physical activity. Once the daily protein requirement has been calculated, the dieter must divide the total amount of protein among three meals and two snacks and determine his/her allowable amount of carbohydrate and fat intake .Dr. Sears suggests that Zone dieters should never go more than five hours without a meal and should try to eat no more than 500 calories per meal or 100 calories per snack.
