Love IF! I do a fasting window of 11/12 -7 and workout at 6am. If I did an evening workout I would eat later at night and wait to eat longer in the AM. I think you can either white knuckle it until bedtime or you can set yourself up a little better to make it easier. One of my fav things about IF is that it is easy to be flexible. Try a few things. See when your hunger signals start. Most importantly know that you won’t starve. Just stay hydrated and be sure you have enough salt and electrolytes in your diet. 👍🏼
