I agree with BGF.
If you want to cut then this is what Id do.
IMO people dont cut hard enough as they're afraid of losing muscle.
183lb at 15% so ~147lb of lbm.
Protein ~180g so 30g per meal. 1.25 x lbm (too much protein and it becomes hard to get lean as too many calories. many overeat protein in fear of losing muscle. 1.25 x lbm is more than enough).
Carbs ~220g 1.5 x lbm. so spread over 5 meals and add more at breakfast and post.
Fats - no direct fats other than an egg yolk or two, a beef meal and fish oil.

Try something like this:
Meal 1
1 cup of egg whites
1 whole egg
1 cup of oats (measure uncooked)

Meal 2
5-6 oz chicken
3/4 cups cooked rice (brown/white)

Meal 3 Post workout
6oz lean beef
12-14oz potato (sweet/white)

Meal 4
5-6 oz fish (white / tuna)
2 oz rice cakes or 3/4 cup rice or 10 oz potato

Meal 5
5-6 oz chicken
3/4 cup rice

Meal 6 no carbs!
1.5 scoops whey/casein (30g protein)
or replace with 1 1/4 egg whites or 5/6 oz chicken eith salad.

add a cup or 2 of green beans or brocolli to meals 2/3/4/5 depending if you want. although good sources of fibre!

take 8-10 fish oil caps throughout day or all at once either breakfast or last meal.

I have no problem gettin to 6-8% every time I cut. obviously I change the diet evry 3 weeks or so by cutting 50g carbs and adding 10g protein.

if you want to gain muscle mass while maintaining then
protein 220g
carbs 220g
fats 60-80g
follow same style as the cutting diet above but add in good fats at meals and protein will be a bit higher so add in an oz of meat at each meal.
if your gaining weight and look okay in mirror then keep with the same diet. if not gaining up by 50g carbs.
stop upping once you find fat gains outweigh muscle gains. its that simple.

good luck!

cut out the dairy, Way too much sugar for ur bf %. U need to Eat some more lean meats and go with brown rice or potatoes for carbs. IMO no carbs after 5-6pm only lean protien and veggies. my 2 cents
