Zone Diet
The diet was created by biochemist Barry Sears, he wrote a series of books about The Zone Diet
which became hugely popular in a short time. The Zone: A Dietary Road Map
(1995) is the initial book on the zone-diet. The diet is based on the simple principle: “40:30:30” fixed ration of calories daily which comes from carbohydrates (40), protein (30) and fats (30) respectively, and aims to achieve hormonal balance and stable blood sugar levels, eliminating cravings associated with it, which in turn contributes to weight loss.

The Theory Behind The Diet.
“The Zone” is the term used by Dr Sears for hormonal balance when insulin levels are balanced (neither too high nor too low), and
glucagon
levels are not too high. When it happens, specific anti-inflammatory chemicals
(eicosanoids)
are released – these chemicals have a similar effect to an aspirin, but does not cause side effects such as gastric bleeding associated with an aspirin. Barry Sears claims that 30:40 ratio of
protein
to
carbohydrates
improves hormonal balance and triggers “The Zone” effect which gives us natural anti-inflammatories good for the heart and health generally. Also, the human body becomes more efficient in caloric balance – it does not have to store excess calories as fat any more and it turns to using stored fat for energy causing weight loss.
The theory is simple. Monounsaturated fats in the meal slow down the absorption rate of carbohydrates into the bloodstream. Slower carbohydrate absorption means lower insulin levels which means less stored fat and a faster transition to fat burning. If the body needs energy and can't burn fat because of high insulin levels, a person feels tired as their brain starves and metabolism slows to compensate. This occurs because the brain runs on glucose and high insulin levels deplete blood glucose levels. Such a condition causes sweet cravings – we eat and start the high-insulin cycle all over again. The best sources of Monounsaturated fat are olive oil, almond, macadamia nuts, and oily fish. Dr. Sears popularized the taking of pharmaceutical-grade Omega 3 fish oil.
Successfull Stories
The study carried out by The Scientific American Frontiers compared the effectiveness of several popular diets including the Zone diet. The participants on the Zone experienced the greatest fat loss while simultaneously gaining muscle mass. Participants also reported the Zone as the easiest regime to adjust to, feeling less tired and hungry. Most people who report fatigue find that the fatigue diminishes by day 2 or 3
The most famous case of someone using the diet effectively has been Manuel Uribe. His weight reached 597 kg (1,316 lb) and he was one of the heaviest people in medical history, but within 2 years he had lost about 237 kg reducing his weight to 360 kg by October 2008. His devotion to the Zone diet has been the only weight loss program to have such a positive effect on him after decades of failed weight-loss methods. His effort to loss weight continues, in fact being on 2,000 calories per day divided into 6 meals, Manuel’s biggest problem is not lack of appetite control, but eating all the food he is supposed to eat.
The Hollywood stars, including Jennifer Aniston, Renee Zellweger, Cindy Crawford, Charlie Sheen, Tiger Woods, and Tom Cruise are believed to have followed the Zone diet.
The Zone Diet is a very good program and much more than just a way to lose weight, it is a plan for life, which will help you to get the body you always wanted and stay healthy as the diet reduces the likelihood of developing chronic diseases.
