Well, if your goal is to build mass, carnivore isnât going to help. Itâs great for your health, but not for bulking. Itâll do the oppositeâyouâll get leaner.
For bulking, you need to be on a caloric surplus. Itâs hard to eat enough calories for this, but easy to drink them. Add a protein shake to your diet with like 4x scoops of the powder. This will put you in caloric surplus for sure, plus youâll have enough protein to build muscle. Consider adding creatine monohydrate to the shake while bulking.
Youâll probably gain some fat too, but you can take that off later by going back to your original diet. It sounds like you probably have an ectomorphic body type, so slimming down post-bulk shouldnât be tough.
