Hi Dee,
I haven't read the article, but just from what you posted I don't think this something that anyone should be using, IMO. In your case, you feed raw except for the little bit of kibble that you give them. So I'm pretttty sure they're digesting at the proper rate for carnivores
. And to give this to pets fed dry doesn't thrill me, either. Dry food digests at a slower rate, and salmonella has been an issue with dry food many times, as indicated by the recalls we see so often. So slowing down the digestion of something that's species-inappropriate and possible also contaminated with salmonella just doesn't make sense to me.
If people want their pets to lose weight and avoid diabetes, all they have to do is remove the kibble and feed grain-free wet or raw. There are no shortcuts, esp. in Nature.
Just my
