Hey guys, I was hoping to get some advice from some of the more experienced people on this thread.
I'm 6'1, 18 years old, and weighing in at about 200 pounds rn. Rough bodyfat estimate is at about 15%. My problem is that im going to be fasting for a month soon from about 6AM to 8PM. All i've ever done is bulk and i figured that if im not eating all day anyways, would it be a good idea to finally start a cut? (Im also excited to be able to see my abs lol) I started bulking when I was 16 and weighed 150 pounds.

I was thinking about Intermittent fasting because I have school and work all day and planning 6 small meals throughout the day for me is just unrealistic. I currently consume about 4000 calories a day and gain about 3 pounds a month. I'm thinking about cutting my calories down to 2500, but once again i have never attempted a cut and am not sure if this is too drastic of a drop. My TDEE is at about 3000 calories a day. My main goal is obviously to shed BF%.

Am I going about this wrong? Will my body being in a fasted state lead me to burn muscle instead of fat?
Any insight would be appreciated. Thank you in advance.
