Macros to Calories not adding up
I am over on all of my macro goals, which should add up to 2800 calories, but Cronometer is saying it's only 2790. Taking 4 Cals per Protein and Carb, and 9 Cals per Fat; this should be 2880 Calories... so what happened to those other 90 Calories that Cronometer is missing?
The calories and the macronutrient values will be a bit off because each food is different in the actual amount of energy (calories) it contains.
You were probably taught the rule that carbs and protein are 4 kcals per gram, and fat is 9 kcals per gram. They are not. They are close but there is better data on some foods and we use that in the calculations for the macronutrients.
For example, some carbs are 3.8, 4.1, 4.3 kcals per gram etc. Same is true for protein and fats. That is why there will be a discrepancy, when our data is more accurate then the 4-4-9 crude estimation.
