Can someone explain to me the concept of Net Carbs?

I'm trying to do a low carb diet (ketogenic) and I am really confused about the concept of net carbs.

Here is one example, a food has 5 carbs and 4 grams of fiber. Therefore the Net carbs are 1 grams. What does this mean? Should I count it as 5 carbs or 1?

    Basically subtract the number of Fiber grams from the Total Carbs and those are your NET CARBS. So if somethings has a Total Carb. content of 20 gms and 5 gms of Fiber, the Net Carbs = 15 gms.

    The tough part here could be that the label breaks out carbs from fiber, so you have to look at does it have 9 with 4 fiber or is it 5 with 4 fiber? In Canada I believe the carbs are total on the package.

    With Atkins Net carbs = total carbs - fiber - sugar alcohols. Not sure about the Keto diet.

    I understand how it's calculated. What I'm confused about is how it applies to a low carb diet when I'm aiming for <30g a day.

    In Canada the labels look like this, so I'm guessing it's total carbs is 13 and net is 10? Am I reading it right?

    This is from Canada labeling website "The amount of carbohydrates in the Nutrition Facts table includes fibre, starch and sugars. Fibre and sugars must be listed under carbohydrates. Starch is optional, which means that a food manufacturer can list it if they want to."

    Atkins would be the same as keto. With Atkins I think it's <20 g Net? So total carbs would be closer to 30?

    It counts as 1 carb. So, you have 29 carbs left. Just like that dude said.

    Also, it can be something like the protein bar I just ate - 22 carbs - 10g of fiber - 10 sugar alcohols = net carb of 2. So you would have 28g of carbs left if it were the first thing you ate in the morning.
