The Zone diet is generally considered to be a lower-carb diet and consists mainly of foods with healthy fats (avocado, olive oil), lean proteins (fish, chicken), and a few carbs (veggies and some fruits). The main goal of the Zone diet, according to WebMD, is to divide every meal into the same ratio of 30 percent fat, 30 percent protein and 40 percent carbohydrates.
According to WebMD, the Zone diet puts an emphasis on the healthiest versions of all three of the major nutritional blocks. Monounsaturated fats obtained from healthy sources like nuts and oils should be favored over other types of fats. Carbohydrates should only come from low-sugar fruits such as berries and veggies, which are naturally low-carb food items. Protein from meats should be restricted to the healthiest versions, which seeks to cut out read met and opt for lean alternatives such as turkey, fish and chicken.
WebMD explains that the Zone diet recommends that a person eat the usual three main meals per day, with two snacks in-between. The main complaint someone may have of the Zone diet is that it discourages starchy foods such as breads, grains, pastas, and potatoes. Otherwise, it is relatively easy to follow in comparison to other more restrictive diets and does not specifically ban certain foods but instead encourages people to choose the healthiest options together in a well-balanced ratio.
