I deeply respect doctors, but I want to be very clear on something: at every hospital in the United States, many doctors are doing the wrong things, pushing pills and interventions when an ultra-aggressive stance on diet and behavior would do far more for the patient in front of them. Suicide and burnout rates are astronomical in health care, with approximately four hundred doctors per year killing themselves. (That’s equivalent to about four medical school graduating classes just dropping dead every year by their own hand.) Doctors have twice the rate of suicide as the general population. Based on my own experience with depression as a young surgeon, I think a contributor to this phenomenon is an insidious spiritual crisis about the efficacy of our work and a sense of being trapped in a system

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.

Thermoneutrality”: A hallmark of modern industrial life is spending most of our time indoors at relatively consistent ambient temperatures, a concept we’ll refer to as thermoneutrality. Interestingly, experiencing swings in temperature is great for mitochondrial function, as cold stimulates the body to generate more warmth by increasing mitochondrial activity and stimulates more ATP generation and use. Heat exposure has been shown to activate heat shock proteins (HSPs) within cells, which can protect mitochondria from damage and help to maintain their function. HSPs can also stimulate the production of new mitochondria and improve their efficiency in producing ATP.
