Negative net carbs

(Daniela) #1

So I’m new to keto diet. I’ve read a lot about it and I compiled some recipes so that I could refer to them and not feel all stressed out when I’m hungry. I have realized that some recipes when you combine the net carbs the overall shows a negative net carb. Is that possible? For example I like tomatoes and avocados together so I have come up with a tomato-avocado combo so that I don’t have to enter them separately in my carb counter. One medium tomato has 4 grams of carbs and 1.2 grams of fiber. a half a cup of avocado has 1 gram of carbs 5 grams of fiber. That means total fiber for the combo is 6.2 and total carb for the combo is 5. Net carbs is 5 - 6.2 which gives -1.2 net carbs is that possible?

Chances are the avocado is already counted as net carbs and the tomato is total. You have to be careful of quirks like that.

Measurement is incorrect. Avocado is 1g net—not total. Should be 6g total

Where do you live and where are you getting your nutrition info from?.. there’s an error somewhere.

As others have pointed out, this is not possible. Fiber is a carb only we don’t count it because it is not metabolized. So your recipe has 2,8 grams net carbs for the tomato and 1 net carb for the avocado, for a total of 3.8 grams of net carbs.

Thank you guys so much. That makes much more sense. The way I got the nutrition info is I just Googled the phrase nutritional information for tomatoes and then the same for avocados. But I did not realize that the avocado one was given in net carbs. Thanks again

Here is a semi-related question…
On this chocolate bar it would be negative 2 net carbs. Now how does that add up if you are counting net carbs only? Do you just leave it at 0 for this food entry, or do you minus out 2 more carbs for your day?
Sorry if this is an ignorant question. I honestly am curious.

Don’t go negative. :wink:

Thanks. That was my assumption, and what I went by. But you can always have hope :joy:

The carb count listed is already net.

(Doug) #11

That’s Allie - always on the positive side. :slightly_smiling_face:

I’m assuming you are meaning you count total carbs, not net carbs? Not that the carb count listed is literally the net carbs.
I personally count both total and net carbs, but at the end of the day if my macros/micros are lacking, I’m not going to stress if I go over on total carbs as long as my net is under 10.
I maintain ketosis without any issues as long as I follow this rule. But I know it depends on each individual on how their body reacts, and their opinion on insoluble fiber. But it’s hard to go over on total carbs if you keep your net 10 or under.

Here’s an example from yesterday of my tracker. Most of my days go like this carb wise.
And my macros are set by my dietician. (I have epilepsy, so that’s why I’m on keto)

The carb count listed is net carbs, same as on other UK produced products.
If you want to count total carbs on UK foods you need to add carbs and fibre together to get total.

Ah! Well that makes sense as to why it would end up in the negatives. The US doesn’t do that. Would be much more convenient if they did. Good to know though. I would have ended up counting it wrong. Thanks.

I know this thread is a little old (I landed here googoo-ing for keto related info), BUT, in general it is NOT possible to get a food that has negative carbs if the food contains and form of fiber and/or sugar.

In the European Union (that includes UK as well), EU law requires that food labeling shows NET digestable carbs, and fiber is shown seperately. In the US, the FDA rules require labels to show TOTAL carbs.

Hope that clarifies things a little for future readers.
