My body fat is around 23% but recently I started cutting and increased my protein to 165g and carbs to 135g, and fat to 38g (which is equivalent to around 1500 cals). 

I want to cut to 15% body fat but I’ve been advised not to start cutting since I’m 17. I’ve been hitting the gym for like 3-4 years now, and usually bulked for the majority of that time (I weighed like 165ib, now I weigh 150ib). I haven’t grown in height for years now, so I don’t think I’ll stunt my growth if I cut.
I’m prepared to lose muscle mass and willing to spend the time needed to regain it. The reason why I want to start cutting is because I’m not happy with my body fat on my abdomen, lower back and chest. I included pictures of me flexed and rested (face removed for privacy).

I'm 5'8 but your estimation was pretty accurate, that's cool! 

If BMR at Rest means that I don't do anything besides watch Netflix all day, does BMR in motion refer to if I'm a guy that takes walks, likes to get up all the time to move around or does it mean I exercise? I guess I'll eat a bit more instead. I burn 300-500 calories 4-6 times a week (depending on what cardio equipment I use). Would 144g carbs, 44g fat, 180g protein (1700 calories) be good enough? 

Also, apparently I read somewhere that I should be eating the same everyday regardless of if I exercise or not, I'm assuming that's just BS? 

Thank you for your response!

Afternoon,

I wouldn't typically recommend a 'cut' because it would be a drastic change what you eat. I always have had the problem of not eating the right things and wanting to lose weight but never the discipline to cut. Basically, walk on the treadmill and get your heart rate up to ~115BPM for 20 - 40 minutes for a cardio workout. I do this as a warm up and cool down when I lift website. My goal is to slowly lose excess fat without sacrificing my workouts.

Clean up your eating habits and step up the cardio a little bit and your lifts a few notches and you'll be able to see some good results.

I hope this could help.
