How accurate is Cronometer?

sadammkhan

The following are my macros:

1 gP*lean weight = 130 520

0.5gF*lean weight = 65 585

Leftover for carbs = 200 800

Total = 1905

Having hit only 92% of my individual macros, somehow I'm at 1983 calories already. How can this be if I haven't gotten all my macros yet?

i've noticed myself, that is i add up all the amino acids, it doesn't equal grams of protein on alot of foods..probably something similar...

as far as 'how accurate is it', it's just a well educated guess...food varies and so do people...

the only thing that you can be THAT accurate about is Vitamin C by doing a Iodine/Starch titration right before you eat it...(which i do time to time) ...unless your really pioneering and willing to drop $1k on a spectrometer and the assay kits for other vitamins...

i had a thought about the 'accuracy' of cron-o-meter...

think of it as driving a car and it's the stripes on the road keeping you in your lane, it's accurate enough to keep you from going off the road, but you can sway a bit to the left or right...

Hi @sadammkhan , I'm not sure I understand your calculations. Is it possible that you have entered foods into your diary which have conflicting macronutrients/ calories?
I would recommend trying to use food entries from our "Common Foods" Tab. Take a look at this Blog post about choosing the best data for your needs: https://cronometer.com/blog/6-tips-getting-nutrition-data/
