It just is not coming off?

I just don't get it. I flew her on the creance again yesterday and she is coming every time with or without tidbit. She hits the lure hard, but she is loosing weight very slow. I am giving her 100 grams every other day and she looses that plus 10 more. I had been giving her washed beef heart when giving her food every day. Than unwashed beef heart when every other day. Yesterday I gave her chicken breast, 100 grams. We will see how that works.
