you determine how many calories
you are going to consume each day, you need to assign a specific Macronutrient goal.
Macronutrients are made up of Protein, Carbs, and Fats, and all should be utilized when you are trying to gain muscle.
I would set your protein goals by multiplying your body weight in lbs by a number between .7 & 1.25.
The number changes based on your gut health and how well your body assimilates protein, so use the above referenced as a guide.
Once your protein goal has been established, you will need to subtract your protein calories from your total daily calories. You will be left with a remaining calorie portion, which can be evenly applied to your carbs, and fats, in a energy balanced diet.
