The meal calorie calculator works out afternoon snack total calc, morning snack total calc and afternoon snack min calc from activity level, after snack1, after snack2, age, breakfast1, breakfast2, calories, dinner1, dinner2, height, lunch1, lunch2, mor snack1, mor snack2, sex, weight and one way. Enter what you have and the relationship is applied straight away, so you get the answer without working through the algebra yourself.
What Is the Meal Calorie Calculator?
The meal calorie calculator gives you an estimate of afternoon snack total calc, morning snack total calc and afternoon snack min calc based on activity level, after snack1, after snack2, age, breakfast1, breakfast2, calories, dinner1, dinner2, height, lunch1, lunch2, mor snack1, mor snack2, sex, weight and one way.
It is a quick reference figure rather than a diagnosis, and it is most useful for tracking how a number moves over time rather than for interpreting a single reading.
How the Meal Calorie Estimate Is Worked Out
The calculation follows published reference relationships, so it is a reasonable approximation when the inputs are accurate. It assumes an average adult and does not account for individual variation.
If you are comparing two people, or the same person over a period of weeks, keep the method and the inputs identical. A change in the method can easily look like a change in the person.
What This Calculator Does Not Do
It does not diagnose anything, and it does not replace advice from a clinician. If a figure comes out at an extreme, or if it differs sharply from what you expect, that is a reason to speak to a professional rather than to adjust the inputs.
Nothing you type here is stored or sent anywhere. The whole calculation happens in your browser.
A Worked Example
Working through an example, with activity level set to 1.2, after snack1 set to 10, after snack2 set to 5, the calculator returns calories of 7,354.8, and breakfast total of 2.75, and breakfast total calc of 4,045.14. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out afternoon snack total calc?
Enter activity level, after snack1, after snack2, age, breakfast1, breakfast2, calories, dinner1, dinner2, height, lunch1, lunch2, mor snack1, mor snack2, sex, weight and one way. The calculator then works through the relationship and reports afternoon snack total calc, morning snack total calc and afternoon snack min calc.
What does the meal calorie actually calculate?
It takes activity level, after snack1, after snack2, age, breakfast1, breakfast2, calories, dinner1, dinner2, height, lunch1, lunch2, mor snack1, mor snack2, sex, weight and one way and converts them into afternoon snack total calc, morning snack total calc and afternoon snack min calc using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter activity level?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Can I use this for a quick estimate as well as a precise answer?
Yes. The calculator is built for quick checks, so round your inputs to a sensible number of significant figures and the result will be just as useful. If you need more precision, keep the same method and add digits to the inputs rather than adjusting the method itself.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
