Hey, so today I decided to take part in my religion's (Jewish) fasting for a full day. It's called Ninth of Av. I do have concerns regarding this because I am not so skinny but still I have been doing alot of sports and especially cardio for the military which is alot of calories burned and hard to get muscle however goal is strength not bodybuilding. Will i have long term negative affects from just a 24hr fast? I have never fasted before though, and I know people do it here because it has alot of good benefits. But it is fasting without drinking water which is why you can't exercise either in my opinion (low intensity). Would love to hear your opinion's regarding this. Thanks!
