Written by author Barry Sears, the Zone Diet books suggest that we balance our consumption of protein, fat and carbohydrates, rather than simply counting calories.

In the zone diet book, Sears explains that this is a way of eating food that complements the body's own evolution.

In the Zone Diet book, you will find out how to achieve a 40:30:30 ratio of daily calories from carbohydrates, proteins, and fats. Achieving this ratio will help to balance out insulin levels and lead to both improved health and weight loss.

In addition to the main title, there are various other publications that will help support those who are following this plan. These include:

A week in the zone
What to Eat in the Zone: The Quick & Easy, Mix & Match Counter for Staying in the Zone
Zone meals in seconds
The 7-day Zone Diet: Join the Low-carb Revolution!
The Top 100 Zone Foods: The Zone Food Science Ranking System

Rather than a quick fix fad diet, this is a long term plan that can have numerous positive effects on health, and is advocated by many health professionals. If you are looking for a permanent solution to your weight problems, it's worth looking into.
