Broth has tons of good stuff that your body craves while fasting. It’s keto so it won’t raise your insulin much and it will boost up your electrolytes. But it will break your true fasted state and partially negate some of the benefits you are seeking. When I water fasted for a week I had no energy the last couple days and I finally caved and decided to have a cup of broth. I felt like a completely different person before I even finished the cup. Great stuff
