Start your fast right after dinner. You’ll spend most of the fasting window asleep — much easier.
Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. It doesn't prescribe which foods to eat, but rather when you should eat them. Common methods include the 16:8 method, 5:2 diet, and eat-stop-eat.
Intermittent fasting may be suitable for many healthy adults, but it is not right for everyone. If you are pregnant or breastfeeding, under 18, have a history of disordered eating, diabetes, low blood pressure, take medication affected by meals, or have a medical condition, speak with a healthcare professional before starting.
Water, black coffee, plain tea, and sparkling water are generally allowed during a fast. These beverages have minimal or no calories and won't break your fast.
