Simple markers can show us “check engine” alerts. A most basic and accessible way to see if you have a reasonable level of metabolic health is by checking five markers that are almost always tested and tracked at your annual checkup: blood sugar, triglycerides, high-density lipoprotein (HDL) cholesterol, blood pressure, and waist circumference. When these markers fall into an optimal range, in the absence of medication — see Chapter 4 for exact specifications — you can deduce that your cellular energy production is doing OK. Typically, you will feel vibrant, healthy, and pain-free. These feelings, too, should tell you that your body has Good Energy, the foundation of general good health.

low-grade activity that occurs more frequently and regularly throughout the day is extremely important for cellular health and glucose control, even more so than chunking all your physical activity in one discrete block and sitting for the rest of the day (a pattern most Americans adopt).

This might sound pessimistic or even frightening, but understanding the incentives of our medical system and why it does not deserve our benefit of the doubt is the first step to becoming an empowered patient.
