But before I have started it, I had lot of doubts like whether it is safe? will it cause health issues? will it aggravate my gastritis? will I be malnourished ? etc etc. Now, it's been 80 days and I am very happy. So felt like sharing and spreading this joy. Intermittent fasting is nothing but incorporating fasting in our everyday life. If I start talking about fasting, the list of benefits keeps on going .

Most of us will be already doing 12 hours of fast...
