There isn't enough research and data to definitively say if dry fasting is good.
While proponents claim dry fasting offers benefits such as weight loss, improved immune function, cell regeneration, reduced inflammation, and delayed aging, the scientific community emphasizes the lack of substantial evidence. Zumpano points out the limited data available to support these claims.
Therefore, due to the limited research and potential risks, dry fasting should be approached with extreme caution and only under the strict supervision of a qualified healthcare professional.
