I hear about how intermittent fasting is so beneficial. But people who skip breakfasts are already fasting unintentionally, right? Just imagine if someone goes to sleep around 11 pm. They ate their last meal around 8 pm. Then they wake up and have no time to eat, so they head to work and then have their first meal around noon.
That's already 16 hours of fasting without trying. So how is intentionally fasting for 16 hours different than fasting for 16 hours just because you were busy?
