Why doesn’t MFP show net carbs? Only shows full, not subtracting fiber or sugar alcohols.

    Because the USA is one of the only countries whose labels don't already show net carbs, so if MFP subtracted fibre from carbs on anything but a USA label, it would be a double subtraction and would be wrong. The database already has millions of entries, and applying an algorithm that subtracted fibre from carbs would render most of the entries completely unreliable. To complicate, thousands of the entries in the database (particularly UK, Eurpoe and Australian entires) ARE net carb, because the info has been taken from labels.

    You should save this for a cut and paste into the incessant 'net carbs' threads which show up on a pretty much daily basis.

    I understand the problem, but given that these requests are "incessant" and presumably frequent, I would assume that a large number of your potential customers would like to have this feature. Being a programmer myself, it doesn't seem too difficult to me to simply have a line item option in the macro nutrition screen that would do that simple calculation for the user, and possibly another option to have MFP calculate the totals based on that instead of the total Carbs number. I assume that you'd want to add a disclaimer explaining that it can make the totals inaccurate when eating foods from other countries, but if a user wanted to do it this way, they'd at least be informed of the risks.

    Perhaps it could be a Premium option . . .

    Could it not be made an option? You can already choose which macros your food dairy shows, so why not just make it one more you can choose from?

    i just add it in my notes , like a thinslim bagel has 16 carbs but when ya subtract the 14 fibers makes it net carb of 2 , so I just do it myself . I know if i write it down I will stay on tract . so if ya look at my diary you will see it in my notes.

    It is not an option because of the reasons listed above

    I don't see those as valid reasons, since it would be turned off my default and only added in if the user chose it. Yes, only American MFPers need this feature, but we do make up a pretty decent portion of the population here, and it wouldn't be forced on anyone.

    You may not see them as valid reasons, everybody wants what they want. But the developers apparently do, because people have been begging for this over and over and over and over again for years and it still hasn't happened. There's obviously a reason for that. Which has been explained above, and in every single other of the hundreds of "net carbs" threads.

    If they haven't seen fit to give the option to alphabetize recipes, which is completely foolproof and utterly uncontroversial, they're not going to implement a half baked, flawed from the outset option like net carbs.


    Our maybe they will. This is MFP after all.

    It seems to me that when "people have been begging for this over and over and over and over again for years" you'd think from a purely capitalistic standpoint, an enterprising complany would think "hey, there's money to be made here." But instead, what we have is customers that want something, and people telling them that they shouldn't want it. Whatever.

    Let's be realistic here. This is only an issue for US users. Further, this is only an issue for US users who are tracking net carbs. That's not going to be a significant number of users, certainly not enough to warrant the writing of a whole algorithm purely for US entries for that small subsection of users. It's just not a sensible business decision.

    Forum population isn't an accurate way to assess business need and low carbers do seem especially vocal about everything relating to their dietary choices so offer a skewed view of need.

    It's a free app...Unless you paid for premium. In which case it's not even an option. Because of the reasons listed. Someone does have a script that does it for you, but I'm not that savvy to recall how it worked.
