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.
Life is about balance. The good and the bad, the yin and the yang. The same applies to eating and fasting. Fasting, after all, is simply the flip side of eating. If you are not eating, you are fasting.
In essence, intermittent fasting allows the body to use its stored energy.
The important thing to understand is that there is nothing wrong with that. That is how our bodies are designed. That's what dogs, cats, lions and bears do. That's what humans do.
If you're eating every third hour, as is often recommended, then your body will constantly use the incoming food energy. It may not need to burn much body fat, if any. You may just be storing fat. Your body may be saving it for a time when there is nothing to eat.
If this happens, you lack balance. You lack intermittent fasting.
