Thus, by fasting, we can regain leptin sensitivity, and by incorporating periodic high-carb, low-fat “refeeds,” we can keep our metabolism revving like a sixties muscle c

Processing food—carbs, fat, whatever—makes it instantly more toxic to your system.

“there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD [coronary heart disease] or CVD [cardiovascular disease].”

The empowering news here is that we can mimic many of these benefits in part by keeping tight reins on our bodies’ production of insulin. We can do this by engaging in brief periods of fasting (which I will introduce in chapter 6), avoiding rapidly digesting sugars, and demoting starches (especially processed grains) from mainstays in our diets to
