I am putting on muscle and do not need to lose any weight.
Don't eat potatoes, rice or oatmeal. Eat lots of fat for fuel (fat has more calories per volume than carbs anyway) and if you are getting this from meat, you will have plenty enough protein for muscle building.
I eat strict paleo and mostly just one main meal a day of meat. I'm building strength and putting on muscle faster than I ever did while eating carbs, protein powder and creatine. Most of the conventional advice is complete nonsense. I spent years in the gym (pre paleo) for pretty much nothing.
I do not carb up or eat after a workout either.
I just work out heavy and regularly. I eat when I am hungry, enough to make me feel comfortably full. If you burn more fuel you will feel like eating more. You don't need to stuff food in.
I also leave two days (sometimes more or sometimes less) for muscle recovery when I target muscle areas.
