I'm telling you guys, I know it's expensive but the Wellness Core grain-free dried food has kept my cat healthy and thin. I also occasionally give her a half of one of their smaller canned food products. She particularly likes the sardine, shrimp & crab flavor. But I never give it to her when she begs for it.

Btw, she's an indoor-only cat. I had to sign a fucking agreement when I bought her that she would never go outdoors without a leash. Which is superfluous since she hates going outside and digs her claws into my shoulder and starts crying loudly whenever I try to carry her into the back yard.
