How many days should I practice intermittent fasting?
There isn't a specific time frame to practice intermittent fasting, if you have not tried it before you could start with 1 day in a week and see how it feels like for you.
The usual recommendations would be the 16:8 to start with as that tends to be the easiest recommendation to start with.
If would like something easier to start with, it could be at having your first meal an hour later compared to normal.
When that becomes super easy and you are confident, you can increase another hour to fasting period till you get to the 16 hours.
One thing to take note is that the fasting window would start 2–3 hours after your last meal, as food stays in the body for 2–3 hours before its digested, if not the fasting window is not 16 hours and something like 12/13 hours.
