Oh for sure, if a guy is in a calorie surplus come the end of the day weight gain will happen, and excess calories will be stored as fat. I just find for myself, and this might go against everything ever written, but this does not happen if I keep the carbs lower and the protein super high, as opposed to lets say 1.5-2x carbs to protein ratio. My metabolism being light speed might play a factor, also a lot of my diet advice or even the way I think is strictly from trying stuff and seeing if it works or not, I don't follow a certain protocol when it come to dieting I just one thing and tweak it and try something else to see what gives me the best result. like weve said everyone is different. I personally rock a lot of simple carbs and gain like crazy, whereas some dudes would ballon up if they did that.
