Metabolic Engineering™ is a dietary program personalized to you. Simple blood tests tell you how to adjust each of the three dietary components of Metabolic Engineering™ to your unique biochemistry and genetics. Consider these blood tests as navigational channels to keep you in the Zone at every stage of life.

Adjusting the Zone Diet
You know if you are following the Zone diet correctly if your triglyceride/HDL cholesterol (TG/HDL) ratio is less than one. You can get this information from your blood test at your annual check-up.  If your TG/HDL ratio is greater than one, you are likely consuming more carbohydrates than you should. You can adjust this by eating fewer low-glycemic carbohydrates with the 30 grams of protein in your meals.

Adjusting Your Omega-3 Fatty Acid Intake
Inflammation is critical to survival, but you must keep it in an appropriate zone for optimal health.  This can be determined by the ratio of AA to EPA in the blood.  You want to maintain that AA/EPA ratio between 1.5 and 3. The average American has an AA/EPA ratio of around 20, indicating a highly pro-inflammatory diet. If your AA/EPA ratio exceeds 3, take more omega-3 fatty acids as a dietary supplement.  If your AA/EPA ratio is less than 1.5, take fewer omega-3 fatty acids as a supplement.

Adjusting Your Polyphenol Intake
You want to maintain your HbA1c level between 4.9 and 5.1 percent. The average American with insulin resistance has a HbA1c level greater than 5.7. If your HbA1c level exceeds 5.1 percent, consume more delphinidins as a dietary supplement. If your HbA1c level is less than 4.9 percent, take fewer delphinidins as a dietary supplement.

Getting to the Zone is based on science rather than hope. Your blood will tell you.
