Hey guys & gals!
quick question- I'm a distance runner/rock climber + cross training for both.

I'm 5' 5'', 138lbs, probably around 21% BF. I would really love to be around 16-17% (personal preference and performance wise). I'm of the mindset that I need to count calories to really lose the weight/body fat.

Is this really necessary if one is following primal guidelines? I've looked up some of the article on here, but didn't get a clear response ( I know responses on here are all of personal opinion)- What is your opinion on this?
