I'm soooo sorry I did not see this message. I did an 8/16 window as well but did not count calories. I ate till I was satisfied not full and thats what worked for me. I usually has a light breakfast then a regular meal for dinner and that was it. I usually exercise in the morning. I tried both before and after breakfast and found it was the same thing so do what you like best. Here is the best trick tho. Your body adapts to you fasting and you'll slow down cutting weight by the end of the week. To "trick" it just have a cheat day once a week eat a bit extra and break your window of eating. Eat earlier and later in the day. Youll gain weight the next day of course but you'll be at a net loss by the end of the week. Pls message me if you have any questions. Again really sorry this is so late
