Can I drink tea while fasting?

Plain tea (no milk, no sugar, no honey) is essentially zero calories and is generally fine during a fast. It may even help — caffeine and catechins support fat oxidation and can blunt hunger. Strict autophagy-focused fasters avoid anything that triggers digestive enzymes; for them, even tea is debatable. For weight-management or metabolic fasts, tea is one of the best fast-friendly drinks. Avoid bulletproof-style additions (butter, MCT oil) during the fasted window.
