loosing bf

iv been really having a hard time trying to loose weight and bf. i keep bouncing up and down , im am getting results but their not constant plus im loosing to much strength . at any rate iv developed this diet and workout plan and hope it will work out for me. im at 18%bf 207lbs 6'1 . 3 years ago i used to be 308lbs so i lost lots of weight since but i think i screwed up my metabolism big time with too many crash diets and all. i have good shape now and feel much better but i really want to get below 13% bf with no juice. iv started an ECA 5 days ago. heres what im doing now:
sat: back traps and cardio . 230 g carbs 250 protein and about 50 g fat
sun: chest and cardio . 150g carbs, 250 g protein and 50g fat
mon: cardio and abs zero carbs , 250g protein 70g fats
tues: legs and bis 250 g carbs 250g protein 50 g fat
wed: off zero carbs 250g protein 70 fat
thur: shoulder and tris and cardio 150g carbs 250g protein 50g fat
fri off zero carbs 250g protein 50 fat
as u can see im dong some carb cycling . all my carbs come from vggies oatmeal and fiber one cerial and some skim milk plus the sugar from the grape juice i have after lifting. fats are from nuts and olive oil and proteins from lean sources.
does this look like a good diet/workout plan for you guys to loose bf? any sugesstions are appreciated i really need some help here
