Custom calculated attributes

Given the net carbs suggestion I already made, it would be useful to generalize this and create custom attributes (based on existing attributes).

For example, if this existed, I could add my own net carb attribute, based on the calculation (carb - fiber).

If you offered Excel like “=(carb - fiber)” syntax, it would open up a lot of possibilities to mine the data in the attributes.

Given I’m a software dev, I may be outside the scope of the typical user, but this app has potential for lightweight data science, if we had some of these capabilities.

    Interesting idea! But quite hard to achieve and outside the scope of what we’re building. With custom numeric attributes (a separate suggestion) you could use the api to read carbs and fibre and save the value of one minus the other. More effort, but more within scope too :)

    I know you already said you won’t do this, but I would like to support this idea. With the new custom attributes, I can track how many coffees I drink, and how many soft drinks I drink, but it would be nice to be able to get an estimate of how much caffeine I drink (e.g. coffee * 200 + soda * 50) so that can be used for analytics too.

    Perhaps this could be simplified to a weighted sum, so my scenario could be coffee weighted at 200 and soda at 50, while Kirk’s net carbs calculation could be total carbs weighted at 1 and fiber weighted at -1?

    Oh, this could also be useful for automatically calculating calories based on macronutrient intake: fats 9, carbs/protein 4, alcohol 7.

    For now this is still something outside the scope of what we’re building with Exist, but totally possible for someone to add with API v2 when it launches.
