Dr. Sears Zone Diet Review: Pros & Cons

For any diets, there are pros and cons. There are people agree and follow it happily, and there are also people who disagree with it. Supporters who advocate the Zone Diet include celebrities and also some health experts who say that the Zone’s recommendations don’t stray far from the USDA’s (United States Dietary Association) dietary guidelines.


The AHA (American Heart Association) classifies the Zone Diet as high protein and does not recommend it for weight loss. They assert that the Zone Diet has not been proven effective in the long term for weight loss. They believe that the Zone Diet is hazardous as it restricts the intake of essential vitamins and minerals present in certain foods. They are concerned that the protein ratio in the Zone diet is too high even if the minimal fat ratio is good.

They also find that  the Zone Diet’s theory on insulin flawed and argues that there is no scientific proof that the hormone insulin plays a big role in weight regulation. The metabolic pathways presented in The Zone which supposedly connect diet, insulin-glucagon, and eicosanoids do not exist in standard nutrition or biochemistry texts. The idea that the Zone diet (or any diet) completely controls the secretion of insulin and glucagon is not supported by the relationship between nutrition and endocrinology . Next, the notion that the insulin-glucagon axis controls the production of eicosanoids is not supported by biochemistry . And finally, the belief that eicosanoids control all physiological functions (including athletic performance, health, and disease) is not only unfounded, it is an appalling over-simplification of complex physiological processes.


The Pros of Zone Diet:

  • It doesn’t keep you hungry or deprived of good tasty food to please your dear tongue.

  • The Zone Diet features good amounts of fruits and low starch vegetables and is low in saturated fats, restricts low nutrition carbohydrates, which is undoubtedly good for overall health.

  • Since you are not significantly restricting any one food source in Sears' diet, you are never totally deprived of the foods you love.

  • If you successfully find your entrance to “The Zone” you will experience slow, gradual, and permanent weight loss.

  • The main purpose of this diet plan that of balancing insulin and glucagon - is fundamentally correct!

The Cons of Zone Diet:

  • Complicated and scientific; the 40/30/30 macronutrient ratio represents the “mid point” to the entranceway of the mysterious place of which Sears speaks—this can be tricky.

  • The daily caloric intake for this diet is determined by your protein requirements - which can lead to incredibly low daily caloric intake –much too low and sometime very hard to stay on!

  • Claiming the 40/30/30 zone ratio creates a positive eicosanoid balance isn't a bad theory - but it's a largely unproven one.

  • Eliminates some essential vitamins and minerals found in certain food.

  • Expensive to follow.

  • Time consuming and inconvenient.
