The zone diet is considered a fad diet created by a biochemist named Barry Sears.

In reality it's not a fad diet in that it is not planned to only be consumed in short periods, but rather to become the normal eating habits for a person. Although less restrictive on carbohydrates than the Atkins diet, it is a low carbohydrate diet.

The basis of the zone diet is a ratio of calories from carbohydrates, proteins, and fats all of 40 to 30 to 30. Television studies have concluded that the diet can work. Some of the studies even showed an increase in muscle mass while on the zone diet. Many of the people in these studies also reported that of all the low carbohydrate diets, the zone diet was easiest to fit into an everyday lifestyle.

The zone in zone diet refers to a hormone balance in which insulin levels are perfect, glucagen levels are perfect, and thus the body releases various anti-inflammatory chemicals similar to aspirin but without side effects. Sears also pointed to heart health as a side benefit of anti-inflammatory chemicals.

The zone diet also creates a state in which the body stops storing fat. The result is weight loss. Various supplements were later added to the diet to deliver certain beneficial fatty acids.

The zone diet calls for the following – a hand full sized piece of meat, as many vegetables as you can eat, and just enough carbs to maintain mental clarity.
