Popularized by the book written by Barry Sears, a biochemist, the Zone Diet has been described as a means of losing weight, fighting inflammations and diseases and attaining better athletic performance. It requires a person to follow a diet that consists of 40% carbohydrates, 30% protein and 30% fats. Sears believes that diets based on this proportion can induce hormone balance which stimulates the body to function more efficiently.
How It Works
The Zone 3 week diet is based on the Sears’ theory that following that ratio would create a balance in the levels of insulin and glucagon in the body. Insulin is the hormone that stores excess calories as fat while glucagon stimulates the liver to release stored glucose when it is needed. This balance can help in enhancing a person’s metabolism and immune system. He believes that having this balance can inhibit the storage of fat. Instead, the body burns fat. He also indicated that the balance of glucagon and insulin can induce the release of anti-inflammatory chemicals in the body. Although there isn’t enough scientific evidence to prove the validity of Sears’ claims, many testimonials can be found in his book.
Because the theory Sears used to base the diet on, lacks scientific validation and left out several factors that can affect the processes in the human body, many medical experts do not agree with it. Several medical professionals, however, believe that the diet is good because it encourages the consumption of vegetables.
What You Should Eat
Following the Zone Diet means that you should have a small portion of protein in all your meals. The size of the portion should be as big as your palm. The rest of the plate should be filled with “favorable” carbohydrates which consist of vegetables, legumes, whole grains and fruits. This is approximately twice the size of the protein on your plate. According to the book, “unfavorable” carbohydrates like high-glycemic fruits and vegetables as well as juice, brown rice, pasta, bread and dry breakfast cereals should be taken in smaller amounts. Eating egg whites instead of whole eggs is also encouraged. It is also suggested that non-fat or low-fat milk should be taken in in place of whole milk.
What’s Good About This Diet
Since the amount of carbohydrates, proteins and fats that you need to eat is consistent, following the diet is easy. At the same time, you can anything you want when following this diet. The only condition is that you follow the prescribed amounts dictated by the Zone Diet.
