I use my fitness pal as well, its my life line. Its a pain to begin with but if you upgrade you can scan bar codes and it inputs the information for you. I would recommend getting some scales though to weight out food.
Most of my protein comes from (apart from eggs)
•Mince meat with low fat content
•Chicken breast is a must
•Tuna
•0% greek yoghurt (make sure its proper yoghurt not Greek style)
•Crayfish
•Salmon
•Steak, rump only for me, less fat content more protein but I do use steak as a treat.
•Turkey breast
•Makrel
•lentils
•Edemami beans are a new fad of mine
I also snack on babybel light, there is 5g of protein in a babybel light. Don't fall for the new protein ones, they are way more expensive and have 6gs of protein in them, not worth it.
You can eat the same as your family, but with slight tweaks. For example if I make spaghetti bol, I dont have the spaghetti, I make courgette spaghetti. Or a very small amount of protein spaghetti, if my carb allowance allows it. Parmesan cheese also has protein, but high fat content, like a lot of cheese.
Im not a fan of protein powder, loads have lots of added stuff you dont need, as well as high carb' content. For the sake of 18g of protein in a shake, I'd rather eat a food source, that will fill and nourish me more.
My go to breakfast is 200g low fat greek yoghurt, 50g berries, 10g of seeds (chia, pumpkin etc) 10g nut butter. This also makes a tasty dessert, just add a small meringue nest, it tastes like Eaton mess. You could swop out the berries for low sugar jam. Or I have a bagel thin with 10g low fat cream cheese and 20g bacon medallion.
I would 100% recommend tracking. You would be surprised where extra calories come from.
