Why do my “Calories Consumed” not seem to match the grams consumed under my “Macronutrient Targets”?

The numbers above don’t make sense. I’ve consumed 13.1g of protein, and that’s more than 51 calories. And I’ve consumed 4.7g carbs, but that’s not 61 calories. The fat calories seem close-ish. What conversion factors are you using? This seems to be throwing off my ratios.

    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.
    It is generally accepted 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.
