Macro nutrients percentages

[muscle99]

How important is it to have your carb protein fat percentage right? Would most of you agree with 40% protein 50% carbs 10% fat for building muscle?

No such thing as the 'right' percentage. People respond differently, find what you respond well too. Personally I'd prefer more fat, but that's an individual thing to a point. Fats play many important roles, whereas carbs are largely just used as energy.
