have u been refeeding every week with 250g carbs for one day??
id say 14-15% is a pretty good ballpark
yeh u need to do cardio when cutting unless ur just very lucky. of course if this were the case chances are we wouldnt be talking right now!
1% bf per week is very ambitious and more than likely not going to happen. 1/2% per week is damn good! thats what id stick with. the reason i askd how long uve been on the diet and about the refeeds is i think u may benefit (depending on ur answer) from running maintenance cals for 2 weeks and then jumping back into another cut. at that time i think would be good to consider a carb cycle diet.
when u cut for 8,10, 12 weeks at a time or longer ur body undergoes adjustments and hormonal changes in response to the deficit in cals. in order to refresh ur body and promote further progress i have seen it recommended to run maintenance for 2 weeks and then re-implement the cut, or a difft cut. in ur case i think ur ready for a carb cycle.
for ur maintenance id suggest week 1: 2500cals, 312g pro, 190g carbs, 55g fat (50/30/20)
week 2: 2500cals, 250g pro, 250g carbs, 55g fat (40/40/20)
after this (and in the mean time) we can re-visit a carb cycle diet for u.
also mentally u could prob use the break.. eat the same (or similar) food choices just increase portions to hit macros.. id start doing some cardio maybe 3 days per week as well.
