Picked up a can of coconut milk for 69 cents. 1/4 cup is only 1.5g carbs. And you certainly wouldn't use that much to lighten your tea. Heavy cream is 1g per 15ml, which is a tablespoon. I like my tea a bit creamier, so I can be more liberal with the coconut milk. Ups your fat and tastes good too! Thought I'd share my discovery...
