    "Net carbs" calculations-anyone else have a problem with this?

    I see this "net carbs" idea sometimes, like today it came up in a post on another site about so-called low carb bread, which I'm not so sure about.

    The CW on this, if I understand it right, is that net carbs = carbs minus fiber.

    So if you have 35 g carbs, but 30 of those are fiber, net carbs is 5g, so eat up!

    I dunno. Something about that just doesn't seem too precise.

    If I am minimizing carbs for a good reason, like insulin resistance, does my body really go "oh, this one is fiber, cool!"

    What am I missing?

    (Apologies if this was covered already. I did some searching and didn't find much worthwhile. It seems like this would have come up before.)

    Yeah, it feels like cheating to me. I've seen a product at my local Real Foods store where the fiber was actually greater than the carbs. If you ate that all day, you'd be EARNING carbs. WHAAAT?!

    I guess it's not just me. That's good.

    What's happened, in practical terms, is that food companies jumped on this to exploit it right away in their labeling.

    Now you can sell bread or crackers with "No Net Carbs!" Yee Haw.

    Add some carpet fibers to the dough, and pretty soon you have negative carbs. Eat the bread, it magically makes you thinner. I just don't think so.

    It seems like someone would have picked this apart and de-bunked it by now, wouldn't they?

    So net carbs don't count in North America? *so confused*

    The label specifically said carbs 4, and the next line was the fiber and it was 5. I'll take pics tomorrow. It'll help me get my walk in to hike over to the store

    The label might be wrong, I've certainly seen that. Just putting that out there.

    I can't remember what the product was, but pretty sure it was a coconut product. Will go look at it tomorrow morning (store closes in 1/2 hr and we're sitting down to dinner, otherwise I'd go tonight)

    The problem is that the net carb thing gets used to artificially "disappear" the carbs in food. By adding fibre and other weird stuff that supposedly acts like fibre, the maker can then make something "zero net carb" when there's actually a fair bit of carbohydrate in it. It's similar to the WW thing where you could earn extra points by adding fibre to stuff. Adding junk filler sure is a good way to sell a "diet" product, even if it's probably crap for your body.

    On the other hand, if you're eating whole foods, counting net carbs might be more reasonable since you're not artificially tweaking the ratio, just eating foods that have very little digestible carbohydrate as a portion of the whole.

    Hey, do whatever works for you. I get tangled up enough in tracking as it is without trying to do net carb math too ; )

    I haven't tracked in a while but I'm doing a tracking week on Fitday to see where I'm at--that's a handy tip!

    I loathe fit day. IMO, dailyburn is more user friendly. It's a pain to find the specific foods on fitday. I cringed when I saw in Mark's new cookbook that he used fitday to calculate the nutrition. How does he know he's finding the EXACT item? Dailyburn seems to have a better database. It has pie charts, too
