Tracking Net Carbs- Keto/Low Carb Integration jess_fitlife — Sep 12, 2018 04:32PM PDT

Hello there,

I have begun the Ketogenic Diet, and in doing so, I need to track my Net Carbs. When I started researching how this can be done on MFP. I came across this same question year after year in your public forum. Why hasn't MFP added this feature? Low carb/Keto Diets have only gained popularity. I am now looking at using the Cronometer and Carb Manager apps in place of MFP. Do you know if this update is in the works or not going to happen?

Thank you!

Thanks for posting your question. Though many features may seem like an easy addition, there are many behind the scenes complications for even the simplest of request, especially since our program is so complex and runs on several platforms. We currently do not have a feature roadmap available to share and we generally do not announce features before they are ready for release.

We will certainly pass on your feedback, letting our developers know that you are eager to see this function added as soon as possible.

Warm Regards,
MyFitnessPal Staff

That response aside, I suspect a big reason MFP doesn't have a "net carbs" function becasue there is no such thing. Or, more accurately, "net carbs" is a marketing term that has potentially as many different definitions as there are products advertising their "net carbs". It's not a term with a consensus definition in nutrition science, nor a term with a legal definition set by the FDA for package labeling.

The biggest holdup appears to be alcohol sugars - we don't really know a whole lot about how they interact with the body (other than that they definitely cause digestion problems for a lot of people if consumed in large quantities). They appear not to be entirely indigestible for most humans, which means their non-inclusion in many "net carb" ratings subverts the intent most people have of such a measure, which I think is to measure those carbohydrates that are digestible and can be burned for energy by humans, in order to follow low-carb diets.

If you're eating mostly whole foods and not heavily processed foods (especially those with high contents of modified alcohol sugars), you can find the amount of carbs that have a caloric impact simply by subtracting dietary fiber from total carbs. So, for the validated measure, it's actually already there, though it requires one additional step of arithmetic.
