I’ve mentioned the concept of the minimum effective dose before, or the smallest dose that provides the desired outcome or effect. This applies to exercise, to sunlight, to carb intake, and to calories in general.
It is this caloric efficiency that describes my goal for the last dozen years: How little can I eat and retain or build mass, have optimal energy, never get sick and still NOT GO HUNGRY?
