I'm currently doing a 12 week challenge and want to lose bf. I'm 20% now was 25%. I've continuedly dropped cals as weight decreased. I weigh 117lb. Questions is as I drop calories what should my macros be? Right now I'm at 159 carbs 147 protein and 53 fat, as I cut should I lower carbs and keeps diet higher in fats and protein? And then have a refeed day once every 7-10 days??
