I was a few kilogram overweight so I started 1-hour exercise and intermittent fasting a few months back. I have lost around 5 kgs and everything was fine till I noticed that my period is 3 days late this month (which never happened before) and I'm facing a hair loss problem as well (from the past few months). My fast time is 9 pm to 2 pm (17 hours). I don't consume any solids during this time, just tender coconut water at 12pm (which means after 12 hours fast). I have nutritious food at 2 pm and 8 pm and work out at 11 am and 6 pm. What am I doing wrong? Should I stop IF? Or should I continue?
