Unsweetened tea?

Hey guys sorry if this is a stupid question, haven't done IF in ages and just started again last week. Is unsweetened tea okay during the fasting window? Had a Venti Peach Citrus Tea Infusion, unsweetened, from Starbucks. AFAIK it's zero calories and carbs if unsweetened. I also have some flavored teas at home, also zero cals/carbs unsweetened. Does it matter if it's flavored (not with syrups, juice or artificial flavors), as long as no calories and carbs?Thank you! via /r/intermittentfasting https://ift.tt/2jiiYCe https://ift.tt/eA8V8J
