Frequently asked questions
Why does the calculator give a range instead of one exact number? Dietary guidelines recommend fat make up 20-35% of total calories rather than a fixed amount, so the calculator applies both percentages to your daily calorie figure to show the low and high end of the recommended range.
Why is fat's calorie value (9 kcal/g) higher than protein or carbs? Fat is more energy-dense per gram than protein or carbohydrates, which each provide about 4 kcal per gram, which is also why relatively small amounts of fat can account for a large share of daily calories.
