Intermittent fasting
Intermittent fasting (IF) isn't about what you eat, but when you eat. It involves cycling between periods of eating and fasting, with popular approaches like 16:8 (16 hours fasting, 8-hour eating window) or 5:2 (normal eating 5 days, restricted calories 2 days). IF can be layered onto any dietary pattern and may improve metabolic health, mental clarity, and weight management.
