Intermittent fasting can provide significant health benefits if it is done right, including weight loss, reversal of type 2 diabetes and many other things.
Plus, it can save you time and money.
It is important to realize that this is normal and humans have evolved to fast for shorter time periods - hours or days - without detrimental health consequences.
Body fat is merely food energy that has been stored away.
If you don't eat, your body will simply eat its own fat for energy.
