High Protein Low fat

What are your macro targets in grams or calories?

I'm on a similar breakdown, though slightly more overall cals. Protein powder makes a big difference. Also, chicken and low/zero fat dairy. Beef jerky, certain cuts of beef/fish. Low fat ground beef.

I'd talk to your trainer and see if you can up your fat to 30% possibly. Fat does not necessarily make you fat - I find myself much more able to attain my protein goals when I give myself a little more wiggle room with fat. Personally changed my macros to 40c/30p/30f relatively recently and have really found it more fulfilling & satiating. Unless you have a medical condition that dictates low-fat, I'd talk to my trainer/doctor about changing it up some to find what works best for you while still maintaining the deficit.

Otherwise - when I was eating less fat, I incorporated a lot of extra lean ground turkey and boneless skinless chicken breast into my meals to get the protein up and the keep the fat down. Protein powder too, if you can stomach it - not my thing but some love it (I know my husband does). Also quest bars in a pinch.

If you like tofu, you can do what I do with it:

Take one block extra firm tofu, slice it up however you wish into equally sized slices (I like to cut it horizontally into 14 slices, then once vertically for approx 34 squares). Preheat your oven to 450, put parchment paper down on a baking sheet, and toss the tofu squares with whatever marinade you want (I use liquid aminos because i love the salty flavor, but you could do a teaspoon of olive oil with spices instead, or maybe lime juice, etc).

Bake the tofu squares for 20-25 minutes, until they're fairly dried out and browned along the edges. They keep for at least a week, but I end up downing them over the course of 3-4 days.

I usually pack 5-6 squares every day as my midday snack-once they're cooked and cooled they get nice and chewy and satisfying.

How much fat is that? 20% of 1600/1700 sounds pretty low to me (not sure though as your diary's private). Maybe ask your trainer if there's some leeway between carbs and fat.

If not, white fish, chicken, turkey, Greek yoghurt, whey etc.

Losing weight is a function of calorie balance (intake vs. expenditure). If you are at a stand still with your weight loss, it is because you are not achieving a deficit, and instead are at a maintenance calorie level. Reexamine how much you are eating and how much you are burning. People usually underestimate intake and overestimate expenditure.

Your macro ratios, in and of themselves, do not affect your weight loss, calorie balance does. However, your macro ratios do affect hunger/satiety, mood, blood glucose levels, how much muscle you retain as you lose weight, and other aspects of health.

Having a higher fat goal may make it easier for you to comply with your calorie goal and therefore help you to stay in a deficit. You might experiment with lowering your carbohydrate goal slightly and raising your fat intake to see if you find it easier to hit those targets and stay within your calorie budget.

Generally, it is better to determine your macro goals based on your weight and not based on percentages. You might want to check out one of the many threads regarding setting macro goals: http://community.myfitnesspal.com/en/discussion/819055/setting-your-calorie-and-macro-targets/p1

I saw you mentioned that you have a thyroid issue. You should probably up your protein and dial down the carbs and fats. I have Hashimoto's disease and my doctor and nutritionist have recommended a diet of 40% protein, 30% carbs and 30% fat. I am eating roughly 1600 calories a day. If you have thyroid issues, carbs are not your friend. Since I started eating higher protein, I feel amazing. My energy is much higher, I don't feel hungry, and I'm having fun playing with different flavors without adding fat. My fats mostly come from avocado, coconut oil, or olive oil. For high protein snacks, I like combat bars. My favorite is the peanut butter crunch one. It doesn't have that weird protein aftertaste. If you like iced coffees, chike protein drinks are awesome. I like the mocha ones. With one packet and 10oz of skim milk, it's 30gm of protein (and it tastes great and has 2 shots of espresso in it). For quick meals, grilled chicken tenders, black beans, quinoa, diced tomato and Mexican spices...so yummy. Or throw a can of tuna on a salad.
