Water fast

[purplepurpose]

It's just going to make you dehydrated to one degree or another. This will likely decrease your performance in workouts. As soon as you drink again you will gain all the weight back.

That's if weight loss was your goal. I don't see how it's a good way to achieve any goal. As LFC said, it's pointless.

The point of short-term water only diet is to divert all energy from costly food digestion that extracts nutrients to let body make full cleanup and repairs.
