at 183lbs its hard to guesstimate ur bf% maybe 16(ish)
183 x .84 = 153.72
153.72 x 15 = 2305cals (rough maintenance)
I always end up at around 2,8k when doing TDEE calcs, so I'm assuming that 2305 my BMR?
i think a big part of ur problem is not how much ur eating but
WHAT ur eating. how much cardio u doing?
Yeah, my diet would absolutely benefit from being cleaned up, thing is: I got my GF on board to loose some weight as well this time, and she needs it far far more then me. 5'6,9"@ 230lbs, her attitute towards food sucks big hairy..., if it doesent taste good, she just won't eat it. (working on that tho). AND she works at McD... So in an effort to keep her from eating fries and burgers I try to make the food we eat as healthy as possible while still tasting good, so she wont throw it in the garbage and grab a milkshake at work instead. I'll get rid of the bread in my own breakfast tho. As for cardio I do 2 days HIIT a week (kick-n-punch, working a sandbag and mitts) for about 1h15m each time. Aside from that I've got a crosstrainer at my disposal.
id try something like:
workout days:
2300cals
275g pro
Last time I ate 300-400g of proteins a day my wee ended up frothing, probably from excreted proteins, and my doc told me to cut back on P, and drop the creatine, cause it was taxing my kidneys. I'll up P a bit at a time tho, and gauge the outcome 
200g carbs (150g pre workout/50g post workout only)
I work out almost first thing in the morning, 'cause I work evenings, so this will be hard to fully incorporate
44g fat
non-workout days:
200g pro
green veggies only carbs
44g fat
id hit cardio hard on non training days (60mins) and do no cardio on training days. try to alternate light intervals and moderate cardio. u need to gain some muscle and lose some fat. i would suggest u consider a routine that is upper body one day then lower body the next day. lift EOD. cardio by default will be EOD.
go for big lifts. such as:
upper day: bench, deadlift, shoulder press, rows, abs (no weight needed IMO); (3 heavy work sets (5-6 reps) for each, be sure to warm up good. i like to get on a piece of cardio equipment for 5 mins before i lift and have found it to be more effective than warming up with weights.
Right shoulder is utterly buggered, so my delt and pec WO's are fairly gentle still.
lower day: squat, leg extension, leg curl, calves, traps, abs (same applies here for work sets and rep range)
I'd love to be able to, but long story short: my Endo refused to give me treatment for my low T, cause I'm not 40 yrs+?? so Im on unapproved TRT (equal to 100mg/week, undecanoate ester tho so less frequent injections. And alot of ester weight), which will land me in jail if I get tested at a gym, and they do test the gyms around here completely at random several times a year. Ive had a few close calls before, so now its home workouts only, no spotter, 2nd floor of the house. I cant do too heavy deads, atleast not to failure, cause I'll have to gently lower the weights. Same with squats etc. I use DB's, got some fairly heavy ones which I can load up to around 150lbs on each. One legged squats, and stiff legged deads are the only leg exercises I've managed to think of so far :P
as regards to ur diet i am finding maintaining an anabolic environment for training days is ideal and get ur fat burning done on non training days. depending on ur progress u could also consider implementing a 6-8hr fast upon waking on non-training days.
100% completely fasted, or can I put a drop of milk in my morning coffee? :P not a problem otherwise tho, I'll give this a go!
u need to have a diet that includes more lean meat and complex carbs and good green veg like spinach (think chicken salad - not the kind with mayo but rather a salad with chikn in it

)
Did stuff like this alot for a while, I have no idea why we just kinda.. stopped :P More often we'd cook a nice steak or similar tho, and make a nice salad, and that'd be it.
post ur diet for review and be sure to include cals and macros.
I'll figure something out, probably this weekend when I get some free time, and get back to you with that.
