Time-Restricted Eating (16:8 IF)

What is Time-Restricted Eating (16:8 IF)?

Eat all your food within an 8-hour window, fast for 16 hours. The easiest fasting protocol: skip breakfast, eat from noon to 8 PM. Improves insulin sensitivity, promotes autophagy, reduces inflammation, and most people lose weight without counting calories.

Is there evidence for it?

How do you do Time-Restricted Eating (16:8 IF)?

1. 1.Choose your eating window: most popular is 12 PM - 8 PM (skip breakfast). But any 8-hour window works — pick what fits your life
2. 2.During fasting hours: water, black coffee, and plain tea are fine. No calories, no sweeteners (even artificial ones may trigger insulin)
3. 3.During eating hours: eat normally. Don't try to diet AND fast simultaneously — that's unsustainable. Just eat real food in your window
4. 4.Start with 12:12 (most people already do this naturally), then shift to 14:10, then 16:8 over 2 weeks. Your hunger hormones (ghrelin) adapt within 3-5 days
5. 5.Track: energy levels, hunger patterns, weight, sleep quality. Most people report more energy and less brain fog after the adaptation period (days 3-7 are the hardest)

How long does it take?

No extra time — saves time actually (no breakfast prep).

Is it hard to start?
