The Zone Diet, the popular diet by Barry Sears, is also commonly referred to as the 40/30/30 diet. “40/30/30″ refers to the proportion of each food group in the diet. In this case, 40% of daily caloric intake comes from carbohydrates, 30% comes from protein, and 30% from friendly fats.

The Zone Diet is all about getting into that mysterious place Sears calls “the zone.” According to Sears, this is the place where athletes perform better, where mental focus is enhanced, and life is generally a better place. Getting there is a simple matter of changing your eating patterns to reflect the 40/30/30 ratio, which, Sears argues, is the best way to stabilize blood sugar, promote general well-being, and encourage weight loss.

Why 40/30/30? What’s the rational behind this ratio of macronutrients?

The whole point of this 40/30/30 ratio is to balance two main metabolic hormones – insulin, which promotes the storing of excess calories as fat, and glucagon, which promotes the burning of fat. Sears also claims The Zone diet also promotes a positive balance of the body’s microhormones (called eicosanoids). 

As a weight loss book, “Enter the Zone”, isn’t too bad a read. Although his discussion of eiconsanoids can be boring.

If you’re going to give this diet a shot, it’s essential you read and understand chapter 7 – “Boundaries of The Zone.” In this chapter Sears maps out the entrance points to “The Zone.” It’s crucial that you know this “40/30/30 ratio” is only the mid-point of this entrance-way. You will- and this is important-have to adjust your carbohydrate intake according to your personal sensitivity to them in order to find your personal entrance to the “zone”.

The main problem for the average dieter will be finding this sweet spot (i.e. your unique entrance point to “the zone”). This is crucial to the entire plan — if you don’t find it, you won’t lose weight. And if you’re hypoglycemic or hyperinsulinemic, it’s likely that 40% of total daily calories from carbs is too much! If this is the case, I recommend you start with a smaller percentage of daily caloric intake from carbs, and increase them only if you can.

Some benefit of the Zone Diet

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

2. 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!

 

He also talks about the importance of a proper omega 3 to omega 6 oil balance in the diet

All in all, I’d have to say Barry Sears’ diet is probably worthwhile buying – if, and only if, you can read it from cover to cover.
