As mentioned before, one of the primary purposes of intermittent fasting is getting rid of the cellular junk from the body. So, when you don’t consume enough water, the cellular trash will just be "floating around inside and can’t get out. Alternatively, dehydration will also lead to muscle cramps, headaches, and exacerbate hunger pangs, which might make you quit sooner. The solution? Always keep sipping water, between, after and before meals.
