Overnight Fasting Efficacy

Meaning

Overnight Fasting Efficacy is a clinical measure of the metabolic benefits achieved during the period of sleep and the subsequent pre-breakfast hours, specifically evaluating the body’s ability to efficiently transition to and sustain fat oxidation. High efficacy indicates that the body is effectively utilizing stored adipose tissue for energy, maintaining stable blood glucose levels, and promoting beneficial cellular repair processes. This metric is a practical indicator of metabolic flexibility and insulin sensitivity, with greater efficacy often correlating with improved overall health and body composition outcomes. It reflects the quality of the metabolic state during the entire non-feeding phase.
