Yes you can drink bone broth while intermittent fasting and still have your body in the fasted state.
I drank some bone broth along with some tea when I did my intermittent fast and my body did remain in a fasted state and I lost the desired weight I was looking to lose.
As long as you keep the calories under 50 while intermittent fasting you'll be fine and your body will remain in the fasted state.
