Eating Window Question
I am just starting IF and I am a bit confused about eating windows...
I don't fast every day, usually 2-3x a week until my body gets used to it...
My fasts usually have a 5-6 hour eating window...from around 1 PM to 7 PM.
I am striving for an 18-19 hour fast.
I am assuming that that means that I should stop eating 18-19 hours BEFORE 1 PM (at around 6 PM the night before)...or does that not matter, so long as I don't eat for a total of 19 hours in a 24 hour period.
The first seems more logical, but I haven't found this info anywhere...then again I am still new to the IF lifestyle..
I apologize if this is a repeat question but i looked around a bit before asking.
