https://www.youtube.com/watch?v=F7m1H4E6hKI I have been doing IF for awhile and have had good success with it so my family started asking about it.  I had read about it not being great for women, and I wanted to be sure it was safe before my mom and sister started doing it.  I based my decision off more than just this video, but I did find it to be very helpful.  It is working great for both of them so far.
