Before taking the quiz you might want to check out our Zone Diet knowledge base.

The Zone Diet promotes weight loss and encourages eating foods from all major groups in a balanced ratio. The ratio between proteins, carbs, and fats is 30: 40: 30. The main focus is on hormonal balance, reduced risk for inflammation, and healthy eating habits.

Foods that are allowed on the Zone Diet include low-fat dairies, leafy greens, non-starchy vegetables, fruits, oatmeal and barley, and egg whites. Lean poultry and seafood are also on the list of approved foods. The plan emphasizes eating fresh produce whenever possible. Dieters are also encouraged to snack regularly. There are restricted and forbidden foods as well. The taboo list includes foods such as dairy products, bread, cakes and candies, fast and processed food, and red meat. The longest period between two meals or a meal and a snack is 5 hours.

While opponents of the Zone Diet claim that it is very restrictive, there are some health benefits. One is that the plan helps the body to control the way in which carbohydrates are processed and contributes to stable insulin levels. A proper balance between glucagon and insulin is an added benefit. When it comes to results, this depends on whether the goal is improved athletic performance, chronic disease prevention, weight loss, and so on.

There are other benefits for dieters such as increased blood flow, mental clarity, and lower risk for type 2 diabetes, hypertension, and heart problems. Patients with chronic conditions also see an improvement.

The focus on hormonal balance and digestion is the main difference between the Zone and other diets. In the view of Sears, low-fat diets actually contribute to weight gain. Stable blood sugar levels, on the other hand, help the body to burn fat deposits. Dieters are encouraged to drink plenty of water because fat burning causes dehydration, dizziness, tiredness, low blood pressure, and sleepiness.
