Ok, whether it's made into yogurt or made into 'cheese', it starts with a certain amount of carbs, which is all lactose (milk sugar). If the lactose is 98% gone, then you have 2% of the original carbs left.

You do the math. The laws of physics apply. Nothing really disappears, it only can be reconstructed into something else. If the lactose is gone, the carbs are gone. 1g lactose = 1g carb. Concentrated 1g carb is still 1g carb, it's just in a smaller space.

If you take 1 teaspoon of sugar and stir it into 1 Cup of water or 1/2 Cup of water, it's no different amount of carbs, just a different amount or volume of water.

K?
