If youre the weight you say you are maintenance at the most extreme level would be 3300 kcal. That would be if you busted your ass 10 hours a day as a laborer or something of the sort. PLUS lifting. Id advise a 300 kcal surplus so bump to 3600 for a week and see what the scale says. If it doesnt go up cut any cardio if youre doing any. If not doing cardio try and cut your workouts TIME down. After trying that and not getting results bump up 150 kcal/week until you see the scale moving. In all honesty if youre really eating 3500 and not growing maybe you are not doing it right. Are you measuring or just assuming that this meal is a certain amount of calories? Cause you might not be eating as much as you think.
