I fast every Saturdays. Only the first Saturday was somewhat uncomfortable, now I don’t even feel slightly hungry throughout the fast.

If you aren’t painfully thin, your body probably has enough fat reserves to last you a good long while, it’s just that they don’t get tapped into unless all the more readily available sources (glucose, carbs) are exhausted.

Once the body starts to tap into the fat reverses, boom, no need for hunger.
