My brother tried explaining it to me, but I’m starting to think he doesn’t understand it either. *My* understanding is that net carbs is based on the digestable and non-digestable carbs in a good. So if it’s 5 grams, but you can’t digest 3, then it’s really only 2 grams of carbs. My brother is saying that as long as he eats fiber, he cns have carbs? Like he can eat pizza because he had a high-fiber vegetable with it. I’m starting to doubt either of us understand net carbs. What’s the deal? What exactly is a carb, and how do net carbs work?

Keto, and other low carb diets like South Beach, are based around getting your body to use fat as fuel and, in many cases, walking back a degree of insulin resistance that tends to come with years of a high sugar diet.
This is also why a number of no-cal sweeteners tend to be banned in these. They are so close to sugar that they generate a lot of the same bodily responses that sugar would, not just the sensation of sweetness.
For this, sugars and the complex carbs that can easily be broken down into sugars are the primary target foe reduction. There are other carbohydrates, chemically speaking, but they don’t all break down like that.
Mostly it’s dietary fiber, which is largely indigestible for humans but can be used to provide structure in recipes like pseudo-bread. You’ll also see keto marketed stuff using sugar alcohols sometimes which don’t get processed the same way as actual sugars or the things that break down into them.
Pizza is…really doubtful unless it’s a speciality thing? The crust is still carrying a lot of the “bad” carbs unless it’s one built not to, and even things like the sauce can wind up with a surprising amount of sugars depending on the brand.
