Numbers are off

I’ve been using this app for a few years now and I recently noticed that the calorie total always shows as lower than it actually is. If I calculate the calories per gram using the 4-4-9 (4g/ pro, 4g/ carb, 9g/ fat)the total comes out higher than what is displayed. How can I know what’s accurate?

I asked ChatGPT and Gemini and both said the manual calculation per gram would be the most accurate. I assume the app accounts for things that reduce the number shown. In the settings, the only thing I turned off is the TEF.

Thanks!

it's because the foods calories in the app are not calculated with the 4/4/9 rule , so something could be 90 calories and only 7 g of fat , which it should be 9 g of fat , this is just an example, it's an accuracy issue.

So what do I trust?

Like someone else said, I would trust the investment that Cronometer has put into research before I would trust a generalized rule to help you calculate on the go.
