I am a female who used to weight lift 4 times a week and prioritise protein and carbs. I made tons of progress, especially in my legs, however after suffering with anorexia and bulimia I've lost 10kg, along with all my muscle and strength. Now that I'm recovering and finally have a healthy BMI, I want to start getting back in the gym. I miss it so much!
For a girl of 44kg (it doesn't sound healthy, however I have a safe BMI so please don't comment on this), my BMR is around 1550 calories per day, and this includes moderate exercise 3-4 times a week. If I were to stick to this amount of calories, using the macros 45% carbs, 35% protein and 20% fat, and weight train 4 times a week, would I be able to build muscle? I know eventually I would hit a plateau, but for now would I be able to build my muscle back up? Please don't tell me that I need to consume more calories, because that's not answering my question. Eventually I will increase my intake, but I want to do it gradually and only when absolutely necessary.
