Beginner9 hrSelf PacedRegistered

Course Overview

What this course is designed to develop

This course surveys the most researched intermittent fasting protocols — 16:8, 5:2, and alternate-day fasting — and explains the physiological shifts (insulin suppression, glycogen depletion, ketone production, autophagy induction) that underlie reported benefits. You will learn how to choose the right protocol for your lifestyle, handle common challenges like hunger, fatigue, and social eating, and adjust variables to match your health and body-composition goals. Note: this course is general education and does not constitute medical advice; consult a qualified health professional before making significant dietary changes, especially if you have a medical condition.
