What can you drink during the 16-hour fasting window?

Water, sparkling water, black coffee (no cream or sugar), and plain unsweetened tea are all permitted during the fasting period. Avoid anything containing calories — juice, milk, cream, or sweetened drinks will break your fast.

How long does it take to see results with 16:8 fasting?

Most people notice improved energy and reduced hunger within 1–2 weeks. Meaningful weight loss typically appears after 6–8 weeks of consistent practice. A 2024 randomized controlled trial found participants lost an average of 4.02% of body weight over three months.

What is the best eating window for 16:8 fasting?

The most popular window is 12pm–8pm because it aligns naturally with lunch and dinner and requires only skipping breakfast. Earlier windows ending by 6–7pm may produce slightly better metabolic outcomes because the body processes glucose less efficiently in the evening.

Is 16:8 intermittent fasting safe for women?

16:8 is generally safe for healthy adult women. However, women may be more sensitive to prolonged fasting than men due to hormonal differences. Starting with a gentler 14:10 protocol and progressing gradually is often recommended. Pregnant or breastfeeding women should not fast.

Can you exercise during 16:8 intermittent fasting?

Yes. Light to moderate exercise — walking, yoga, cycling — is safe during the fasting window and may enhance fat oxidation. High-intensity training is best scheduled within or just before the eating window so you can refuel promptly. Read our guide on intermittent fasting and exercise for a full breakdown.
