(Also, 45y/o) I’m down 50 pounds since February eating 1600-2200 cal per day, high protein low carbs, 5g creatine per day, with the goal of building muscle while losing fat. 5 day split weight training in the morning during the week, usually walk/run 3 miles every evening. I’d figure I’d just be shedding weight at this point, but I’ve stagnated at 325-330 for about two months. Is part of this muscle growth? Do i need to drop my calories (again)?
