Hi Sedlypets ~ I agree with the others that a higher protein food is very beneficial with weight loss. I like the protein amount to be 36 or more if able. I would also supplement the food with a high protein complete and balanced canned food — subtracting kibble to compensate for the canned.
If you continue to think that it might be a medical issue I’d have her thyroid tested using Dr. Jean Dodd’s lab. Her lab is much more individualized — is the animal male or female, spayed or intact, senior or puppy etc. She has diagnosed thyroid issues in pups that other labs have missed.
