Frequently Asked Questions
What is the best intermittent fasting schedule?
The 16:8 method is the most popular and easiest to maintain. You fast for 16 hours and eat within an 8-hour window. Most people skip breakfast and eat from noon to 8 PM. Start with 16:8 and progress to stricter protocols if desired.
What can I consume during the fasting window?
During fasting hours, you can consume zero-calorie beverages: water, black coffee (no cream or sugar), plain tea, sparkling water, and electrolytes. Anything with calories will break your fast.
Does intermittent fasting help with weight loss?
IF can help with weight loss primarily by restricting the eating window, which often leads to consuming fewer total calories. It may also improve insulin sensitivity and increase fat oxidation. However, calorie intake still matters -- you can overeat within your eating window.
