The Zone Diet was invented by Dr. Barry Sears. He created the diet to help people lose weight and avoid disease. The diet follows a specific plan: the 40/30/30 strategy. This means that adherents of the diet are required to consume 40% carbs, 30% fats, and 30% protein.

The Zone Diet focuses on insulin production as the major facet of weight loss. Consuming foods that raise blood sugar and stimulate insulin production are bad for you. Excess insulin is stored as fat. When you eat foods that rapidly produce insulin your body is encourage to store fat rather than burn it for energy. Spikes in insulin are believed to cause heart disease and diabetes.

The Zone diet is specific about the types of foods that help keep insulin in check. Carbohydrates like those found in fruits and vegetables are better than those found in anything made from white flour. Processed foods are a no-no since they contain plenty of empty calories that turn to fat in the body.

On the Zone Diet you’ll eat 3 daily meals and two snacks. Your snacks, of course, will prevent hunger between meals and prevent you from overeating during meals. Choose carefully though and avoid empty calories that will spike insulin production. Your meals will adhere to the 40/30/30 rule. Meaning 40% will come from vegies like corn, cauliflower, beans, squash, peppers and the like. 30% of your calories will come from protein. A good portion measuring device is to eat a piece of protein (chicken, steak, fish etc.) that is about the same size as your palm. And any excess fat should be removed before eating.

Consumption of the proper amount of fat is essential because doing so slows digestion and provides a continuous source of steady energy. Slowing your digestion is good because you won’t feel hungry immediately after eating because your body will be busy digesting. The Zone Diet recommends eating good fats contained in nuts and canola and olive oil.

Foods that spike insulin must be avoided at all costs. Candy, cakes, pies, and other snacks clearly cause insulin spikes and must be avoided. However, other foods can be just as bad. For example breads, pasta noodles, and heavy starches can have the same effect as candy and cake. So try not to eat too much of these foods either especially because these foods are so addictive.

The Zone diet plan offers no special pre-packaged foods to buy so the plan is cost effective. The weekly grocery list is fine with a few simple changes to reflect healthier choices. The foods are ones that children are used to eating so there is no problem fixing Zone approved meals for everyone in the house. They may not even notice the changes in many cases.
