The Zone Diet is based on a scientific approach on weight loss by Dr. Barry Sears - a former researcher in biotechnology at the Massachusetts Institute of Technology. He came upon the science of eicosonoid, which is ubiquitous hormone-like substance that control many vital physiological functions, including those of the cardiovascular system, immune system, and nervous system. It helps to regulate the proportion of carbohydrates, proteins and fats taken into your body. In turn, this balances the amount of body-produced hormones like insulin and glucagon in the bloodstream. Normalizing insulin levels can eliminate food cravings. The Zone Diet follows a meal-ratios formula of 40% carbohydrates, 30% protein, and 30% fats, sometimes called 40:30:30. It can be considered a low ‘carb’ diet due to a low carbohydrate proportion with a low calorie count. The Zone declared to have a standard weight loss from 1-1.5 bounds per week.
The Zone diet's eating plan is a combination of a small amount of low-fat protein at every meal, fats, and carbohydrates in the form of fiber-rich vegetables and fruits. Zone diet considers “unfavorable” with mostly high glycemic foods and foods high in saturated fats. Certain carbohydrates that can release glucose quickly are also restricted such as grains, breads, pasta, rice, etc. Participants are expected to eat at last three meals and two snacks a day to stay within the "zone." Although more frequent meals are consumed, the calories intake should be fewer and also with low-fat proteins in each meal and snack. Portion size is also one of the keys to success. According to Dr. Sears, dieters should divide their plates into three equal sections. One-third should be enough low-fat protein to fit in the palm of hand, and two-thirds should be fruits and vegetables, with a dash of fat such as olive oil. Additionally, drinking at least 64 ounces of water a day is a must.
