Total energy expenditure

Calculate your daily calorie consumptionThis is a very precise metabolic calculator. It calculates your resting metabolic rate and your total energy consumption in calories or kilojoules. This can be a helpful tool for weight loss as it allows you to estimate the amount of calories that represents your energy balance.

 

Instructions:
1. Use the dials until you have entered time spend on sleeping and other activities on a typical day (24 hours).
2. The calculator assumes that all unaccounted time is spend sitting.

Background

The basal metabolic rate is calculated from the Schofield reference formulas used by WHO including age specific formulas for children. Energy cost of activities are based on various references and because children use relative more energy pr. kg body weight than adults, a dynamic correction is used for children depending on body weight.

At the other end of the scale, obese people tend to have their activity dependent energy expenditure overestimated. Accordingly, a correction factor for body mass indexes over 30 is applied.

In summary: this calculator is reliable for children as well as normal weight and obese adults.

Thank you so much for this very useful tool! It has healed my relationship with food. I had no idea that my body burned this many calories! It is awesome to know I can eat satisfying amounts of food and lose/maintain weight. No need to slash calories to proverbial 1200!

Dials don't work at all - anyone know why?

The height doesn't work, it doesn't affect the daily total. That can't be right.

The energy expenditure calculator does not seem to be working, when I turn the dial NaN is shown.

Is the height dial supposed to affect the outcome? It spins but doesn't change the numbers at all. Thanks!

Quoting Cali:
Pretty please, could someone fix the calculator. I will pay for the service to get it fixed. It saves me so much time when working with others and it's extremely accurate. Thank you!

Try it in IE. I couldn't get it to work in Chrome, but it does in IE.
