Thank you for your valuable feedback and sharing your experience Dr Desai. I also observed it in my parents and grandparents. I know some people try once a week or once a month and they informed me gaining benefits. Any break to digestive system can be great for cleansing. Metabolic waste can create a lot of physical and psychological stress.

I shared the spiritual aspect of fasting in a new article. https://medium.com/illumination/why-spiritual-people-adamant-on-fasting-545665f9d7d5
