Proper Balance - Protein And Carbohydrates

The body needs both protein and carbohydrates, although not in the way other diets have taught.  With The Zone, the majority of your carbohydrates will come from fresh fruits and vegetables instead of bread, starches, pasta, and grains.  This does not mean the latter types of carbohydrates cannot be enjoyed, but instead, consumed in moderation.  Keep in mind that the amount of insulin your body produces is determined by the amount of carbohydrates that enter your bloodstream as sugar glucose.  You will eat only enough protein to meet your body’s requirements and since you will be consuming more carbohydrates than protein, ketosis will never be a problem.

With The Zone, protein, carbohydrates, and fats are all managed in blocks, which are designed specifically to help keep you on track with the foods you consume.  For example, the carbohydrate block consists of 9 grams being the type of carbohydrates that would promote insulin.  The number 9 was used specifically since the body needs 9 grams of insulin-promoting carbohydrates to balance the 7 grams of protein hormonally, which is how the protein block is defined.  Getting your carbohydrates from fruits and vegetables will provide your body with a substantial amount of fiber and important levels of minerals and vitamins.

A glycemic index table is also provided at this site as an important reference.  The higher the glycemic index of a specific carbohydrate, the quicker it will enter the bloodstream as sugar.  Generally, glucose is the only simple sugar that can enter the bloodstream, and the faster it enters, the more insulin the body produces.  This means that carbohydrates with a high glycemic index have more impact on the amount of insulin being secreted than carbohydrates with a lower index.

Some fibers play a role in the glycemic index as well.  With fiber, there are two types, soluble and non-soluble.  The soluble fiber actually slows the rate in which carbohydrates enter the bloodstream.  This type of fiber is the kind you generally find in many breakfast cereals and apples.  Non-soluble fiber is found in cellulose and bran, which does not help to slow the entrance of carbohydrates into the bloodstream.  Another important consideration is how carbohydrates are cooked.  The longer they are cooked, the more the cell structure breaks down, resulting in the carbohydrate being digested faster.

While carbohydrates are not good for anyone, some people are exceptionally sensitive.  To determine if you are extra sensitive to carbohydrates, pay attention to how they affect your body.  As a test, fix pasta for lunch and the monitor how you feel 1 to 2 hours later.  If you feel exhausted and you have difficulty concentrating, then you are sensitive to carbohydrates.  Remember that no matter what you have been told before, you do not need to eat heavy, frequent intakes of carbohydrates for your mind to be clear.  In fact, when you eat too much carbohydrate, your body will react by boosting the amount of insulin secretion as a way of driving down the sugar in your blood.  Instead, your body needs a balance of carbohydrates, or a “zone.”  This zone is what helps maintain the amount of insulin being produced by helping you eat the right kind and right amounts of carbohydrates – not too much and not too little.  The reason people are overweight is because the levels of insulin in the bloodstream are increased – it is that simple!
