Keto Coffee & Tea
We ran 459 coffee & tea through our keto rules: 24 pass, 12 need a label check, and 125 don't make it.
Black coffee and unsweetened tea are zero-carb friends. The failures are the mixes: 3-in-1 sachets and instant lattes are mostly sugar with coffee added for flavour. If it dissolves into something creamy and sweet, the numbers rarely survive.
