I am a solid circuit trainer at the gym. I basically do P90x with weights. So instead of regular push ups I do cable type push ups with say 8/10 rep sets. I do not stop during workouts and feel I am in extremely good shape as far as what I can do in the gym. I do 6 days of workouts for 1:15 / 1:30 mins each.
I am stuck at 14% bodyfat and have been for about 6 months. Obviously my diet is the issue.
I'm 175lbs
14% bodyfat
RMR 3200 cals
I have cut out sugars, and eat about 150/200 grams of protein daily
If you're eating 200 grams of protein on a 3,000 calorie diet, this is only 27% of your total calories, which means carbs and fats are too high imo. Let's look further..... I strive for 3000 cals but it is often difficult because clean eating just does not deliver the calorie load as easily.
If you truly need 3,000 cals/day, then you just need to suck it up and eat, bro. I still don't think you need that many cals, but let's keep looking....
All this being equal, I cannot seem to lose a pound of weight. I'm working my butt off in the gym and I have very little to show for it.
What EXACTLY do you do in the gym. Be specific with the intensity and the duration. Then we can guesstimate how many cals you're burning.
I eat very few carbs.
Well, with your protein only taking up about 27% of your calories, this must mean your fats are out of control!I have a feeling that this is the problem with my diet.
not necessarily I do not understand the ratios that I should be shooting for and have looked around on the flagged portions of the website, but most of the information is on gaining not cutting.
Regardless of whether you're cutting or bulking, it doesn't mean the split needs to change between the two at all; only the quantities of the foods you're eating. Many people recommend a 40/40/20 split, but imo, this is individualistic. You need to find out what works for you. When I cut, I had the best results with a 60/20/20 split, but hey, that's just me.
Example of my diet :
This is an EXAMPLE? Or is this what you eat everyday? If you're unsure why you're not losing weight, you need to try and eat the exact same thing everyday. This will eliminate a lot of variables when it comes to figuring out the problem. If you're constantly changing what you eat everyday, how will you know what variable to change to fix your diet?
Breakfast :
Clif Bar - 250 cals, 42g carb, 6g fat, 11g protein
Dont' know what this is, but I would scrap it. All bars you're going to find in a supplement store or online have a bunch of additives, sugar, sat. fats, etc. Not to mention they are a far inferior body building food. Change this meal to a quality protein source, along with some good complex carbs to fuel your workout and get you going for your day.
-Workout- 9-10:30
Postworkout Meal
Isopure 160 cals, 40g protein
I'm not a supplement guru, but if it's Whey post workout, then I'm okay with it, but add some more complex carbs here to replenish glycogen in the muscles.
Lunch
Chicken Breast 8 oz 216 cals, 8g Fat, 32g protein
Egg whites 3 - 51 cals, 10g protein
You only have protein here. You need a 'vehicle' to distribute all this protein to your body. That's why protein-only meals are worthless. I would make this meal pro/fat since you are cutting. Try to keep your carbs surrounding your workout time.
Snack
Sintha 6 Protein *2 400 cals, 28g carb, 12g fat, 44g protein
Drop it and replace with a quality, lean source of protein. Chicken breast, tilapia, lean beef, etc.
Bulgarian Yogurt 90cal, 8 carb, 8 protein
Never heard of it. From the nutrition facts you've listed, it actually doesn't sound that bad, but you're cutting now, so I would stay away from all dairy. Not to mention, we want to keep carbs around workout time alone. Drop carbs from this meal, and keep it pro/fat.
Benefiber 60cals, 14 carb
Again, you're cutting. Get rid of the carbs here. This sounds like a processed carb anyway, which is inferior to other complex carbs like sweet potato, oats, brown rice, etc.
Dinner
Chicken breast 216 cals, 8 fat, 32 protein
Egg Whites 51 cals, 10g protein
PB&J 400cal, 90g carb, 20g protein, 20g fat
PB is fine, as long as it's all natty pb. Definitely drop the jelly. No need for carbs here; especially not plain sugar!! Drop all sugar from your diet, especially if your weight loss has stalled and you 'don't know why'.
bedtime meal
2 Scoops Casein protein 240cal, 48g protein, 6g carb
Not bad; you could even add more pb here if it fits into your daily fat allotment.
Are there any resources that I might be able to use as a reference to design a diet or are there any sample diets that I can take a look at?
Just read the stickies at the top of the page in the diet section, bro. Nearly all the information you need is there. Myself and others will help you with the rest 
I'm really getting frsutrated. Short of starving myself
Don't stop eating altogether!!! Starvation diets do not work, and you'll sacrifice LBM. Don't worry; we'll sort this out., I have never been really solidly under 14% BF. It's really pissing me off. I'm not really gaining or losing anything.
