Well, if you’re happy with your strength levels, then you’ll most likely lose fat (and some muscle) with your current calorie intake. Unfortunately you can’t produce muscle out of nothing. Your body needs the calories in order to pack on mass (muscle).
If you’re eating the extra calories required to gain muscle, there is a chance that you’ll put on some fat, which, once you’re done “bulking”, you’ll burn off with extra HIIT and lowered calorie intake.
Right now I’m eating a lot of food, mostly healthy lean meats, milk, vegetables, fruits, some carbs, protein shakes and weight gainer shakes (high calorie). I’m hoping to reach about 170 lbs and then start cutting whatever fat I may put on during the big eating process.
The important thing to remember is that you’re not just eating and sitting on your ass. You’re still going to the gym and busting your ass off, so it’s not like you’re going to get all fat. Just eat big (but healthy), lift big, and get good rest.
It isn’t necessary to drop the HIIT, but, if you want to put on muscle, you’ll have to eat even more daily calories in order to break that ‘daily requirement’ because of the extra you’re burning off with your sprints, etc.
