Zone Diet Plan Guide: How It Works?
Zone Diet Plan was introduced by Dr Barry Sears, PhD. The zone for maximum calorie burning is 40% carbohydrate, 30%protein and 30% fat. Therefore, it is also called the 40-30-30 eating plan.
Zone Diet is based on hormones, not calories. It claims that carbohydrates make people fat as most of them are insulin resistant. It believes that carbohydrate consumption produces insulin, which causes too many calories to be stored as fat. Dr. Barry Sears also goes on about eicosanoids, which are hormones which are synthesized from essential fatty acids. Zone diet claims that eicosanoids are the most powerful of all hormone systems and have ultimate control over all physiological functions. Carbohydrates create bad eicosanoids which in turn increases insulin production.
With Zone Diet, the nutritional content of each meal should be in the ratio of 40-30-30. The Zone Diet is created based on research done into the effects of foods on hormone production and metabolic activity. It aims to ensure optimal health by using foods to manage metabolic activity and hormone production, which will lead to the zone and, not incidentally, weight control. High profile celebrities like Madonna, Demi Moore and Jennifer Aniston support this diet and are admittedly taken away by the results of the Zone Diet.
Zone Diet works on the premise that human were meat eaters 100,000 years ago and our bodies was designed to handle the demands of a meat-based diet. Human evolutions introduced more carbohydrates into our daily diet, causing an imbalance—mainly due to food grains. Our extra weight could be attributed to the many grains and starches in our diet which we take from pasta, rice, breads and potatoes. Zone Diet’s strategy calls for a return to the diets of our ancestors where meat, fruits and vegetables are the main dietary items.
Zone Diet doesn’t actually prohibit you from any particular food group; however food with high fat and carbohydrates such as grains, starches, and pastas should be avoided. Fruits and vegetables are the preferred source of carbohydrates and monounsaturated fats (such as olive oil, almonds, avocados) are the ideal choice of fats. Zone Diet claims to use food as a drug for overall good health, weight loss and prevention or management of heart disease and diabetes.
