AtkinsMeal Bar, Chocolate Peanut Butter Bar, 8 Bars, 2.12 oz (60 g)

How do these have 4 carbs when the label says 23 carbs?

What is the sodium content in the Atkins bars?

How do you get 3 net carb?

I dont know where else to ask this question, but have any of you lost a large amount of weight off of the atkins diet? Like 30 lbs or more? Thx!
