Bone broth

I’m currently eating three meals a day, one at 8 AM one at noon and one at 4 PM and then fasting from 4p-8a. I’m trying to extend the fasting window and have been thinking about eliminating the breakfast and having bone broth instead. How much does bone broth raise insulin? I find when I have it I usually don’t have it all in one sitting like a meal but I kind of sip it over in the morning but I’m concerned that keeps my insulin raised for too long. It is the brand kettle and fire and I buy it online.
