Does tea take you out of a fasted state

Drinking tea does not break a fast, according to Andrew Huberman from the Huberman Lab. He suggests that drinking water and tea, as well as black coffee, will not affect your fasted state. The key factor determining if you're still in a fasted state is whether there's a significant change in your blood glucose levels. Since tea does not increase blood glucose, it is generally considered safe to consume during fasting without breaking it 1.
