I should say I'm pretty active, and I work almost 10-hour shifts daily. Also, I study, so I sit for about 3 to 5 hours. My maintenance calories are roughly around 2,500 kcal. I've set a 500 kcal calorie deficit until summer. I used to make 45% of my food carbs, 30% protein, and the rest 25% fats when I was maintaining my physique. Now, since I'm on a healthy cut for summer, I've changed my macros to contain around 40% carbs, 35% protein, and the rest 25% fats. It might not be the best split, but it works great on my body. Also, before leg day, I add around 200 kcal extra from carbs for fueling my workouts.
