The Zone Diet is a diet created by Barry Sears, a biochemist who created the diet as a response to decrease his risk of heart attack. The diet is built around stabilizing blood glucose levels and hormone levels and is based on a percent system. The diet is designed so dieters consume 40% carbohydrates, 30% fat, and 30% protein in their total diet. Sears claims this is the best way to protect one’s health while allowing for fast, safe fat loss. Some studies have revealed that his claims may be legitimate — Scientific American Frontiers, a PBS show, discovered that Zone dieters experienced the most fat loss compared to other popular diets.

In addition to these findings, The Zone is a widely popular diet with celebrities, including Jennifer Aniston, Cindy Crawford, and Tiger Woods. It is also being used by the former World’s Heaviest Man, Manuel Uribe, who has currently lost over 400lbs through the Zone Diet. Most dieters learn to utilize his program through his book of the same moniker, which can be found in any bookstore or online. The Zone Diet is also considered a low carb diet by experts, although Sears maintains this is not true. For some individuals it may not be an appropriate choice, due to the lack of nutrients included in the diet.


The Zone Diet prescribes dieters to eat a healthy diet in a ratio of 40% carbohydrates, 30% fat, and 30% protein.

The Zone Diet claims to maximize heart attack protection while stimulating maximum weight loss due to its careful ratio and learning these ratios may take a while for some dieters. Dieters note that following this plan takes dedication and plenty of time to create perfectly balanced meals, and may not suit dieters with less time to spare. Nevertheless, it is emphasized dieters can enjoy their favorite meals as long as it incorporates these elements. It is important to note that no studies demonstrate the type of heart-related claims Sears make, and some debate if he has exaggerated these claims for his benefit. Nevertheless, they are plenty of dieters who claim to have lost a substantial amount of weight thanks to the Zone Diet.

The American Heart Association criticizes this diet for containing too much protein and not enough nutrients, and some worry it may worsen heart conditions. It is why dieters are advised to talk with a physician before embarking on this program, due to the alleged risks.
