Will your dog eat green beans and carrots? They can be used as snacks or as a bit of filler to help a dog feel satiated. 2 of mine love them, the other 2 look at a me like I’m crazy and trying to poison them.
I believe you can only cut back diet so far without sacrificing uptake of vitamins, minerals and such so keep it mind. Others with more knowledge in diet may come along and have more information on the this. Any way to “up” exercise levels?
