Total energy expenditure Print E-mail
energy70This is a very precise metabolic calculator. It calculates your resting metabolic rate and your total energy consumption in calories or kilojoules. The interface is easy to use, despite the rather complex calculations behind the calculator.

Instructions:
1. Use the arrows 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.

How accurate is this calculator? As the TEE on this is the same (with no exercise) as on other calculator (with exercise included).

Cool calculator though, very slick!

kilo calorie is the same as calorie, a kilojule makes up kilo caleries and 1000 kj = 1kcal

1 calories is so small 1 kcalorie is used instead this is the same as 1 calorie as used in nutritional labelling

kj(kilo joules ) and kcal( kilocalories ) is a measurement of energy ie kcal is the same as calories but 1000x of its value ie calories 1000 calories but kcal = 1 kcal
