Question 1

What is intermittent fasting?

Accepted Answer

Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. Popular schedules include 16:8 (16 hours fasting, 8 hour eating window), 18:6, 20:4 and OMAD (one meal a day). It focuses on when to eat rather than what to eat.

Question 2

How do I calculate my eating window?

Accepted Answer

Choose a fasting protocol (like 16:8) and the time you want to start eating. Your eating window is the time between that start and the fasting duration. For 16:8 starting at 12:00 PM, you eat from 12:00 PM to 8:00 PM, then fast until noon the next day.

Question 3

Is intermittent fasting safe?

Accepted Answer

For most healthy adults, intermittent fasting is generally safe. However, pregnant or breastfeeding women, people with a history of eating disorders, diabetics on medication, and those under 18 should consult a healthcare professional before starting.
