What is Intermittent Fasting?
Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. Unlike traditional diets, it doesn't restrict what you eat — it focuses on when you eat. Popular schedules include 16:8, 18:6, OMAD and 12:12 fasting.
Millions of people use intermittent fasting for weight loss, improved metabolism, reduced inflammation, and mental clarity. Our free online fasting tracker helps you stay consistent with your fasting schedule — no account or app download needed.
