setting macros to match exercise

YiotaBro

So, I'm close to goal - trying to lose the last stubborn 10lbs, and I also want to start exercising a bit more and trying to be leaner - still have my tummy pooch

Was wondering what I could set my macros too that would make sense - 40% protein, 30% carb, 30% fat? or is that way wrong?

Should I try changing up any of the other numbers. I'm 140, want to get down to a lean 130 (start seeing some muscle definition), thus far I've only really being doing cardio.
