Eat more protein if you want to put on muscle mass, or gain weight, and eat more carbs if you're just exercising a lot and using lot of energy.

If you don't get enough carbs you won't have as much energy to exercise and train. If you don't get enough protein then your muscles won't be able to increase in size or repair themselves as well. But usually high protein food has a lot of carbs too so I wouldn't worry about it.

If you want to work on your muscles and keep your energy high, then just have a healthy diet, but eat more of it. Foods like steaks, fish (especially Tuna), eggs are all good for protein, whereas pasta, bread, oatmeal are good for carbs. Protein drinks like the Weider stuff are good because you worry less about stuffing your face and you can just drink a shake after a workout.

The RDA of protein is roughly 0.8g per kg, for a normal person. If you're into MA or working out then up it a bit, so...you weigh about 72kg, so officially 60g of protein is enough. Try something like 70-80g. But anyway, I don't think there are any dangers of having too much protein. 160g is overkill though lol, i dunno, it could just make you fat.
