I have been training for approx 3 years and have been increasing calories gradually to gain muscle. I'm naturally skinny and have high metabolism. I am currently up to 3300 calories and not gaining weight yet. I'm a bit confused at when enough protein is enough. I'm currently having 190g per day 380 carbs and 115 fat. Not sure now what to increase as I feel protein increase is not necessary. Articles are so contradictory and I'm off the scale with any weight gain calculator!
