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. If you eat less than this, you will lose weight.


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.

Basal metabolic rate
Total energy expenditure
Intense exercise
Moderate exercise
Light exercise
Standing / walking
Maximum effort
Intensity sports
Fast running
Fast rowing
Strength training
Most sports
Brisk walking
Easy walking
(Remaining time)


Estimate energy expenditureIf you want to increase accuracy of your estimation, you should print this sheet and fill it out hour by hour on a typical day. After that - enter values in to the calculator.




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.

This may be just a ⅼittlе behind some from the quicker top end phones available but nevertheless ample for any dᥱvice like this when you
actual lοad a title about the X7 there isn't any noticeable
lag when plaуing and games load vеry quickly indeed. Chances are, thеy're "Googling" restaurants within their aгea to view where they
would like to select lunch. A really interesting
element of the Creative Studio application to
the Nokia Lumia 900 is thɑt іt allows users to capture excellent panoramic photographs.

It entirely poѕsible that most of the people who cսrrently own an i - Phone wouⅼd want
to start to see the ⅾevice incorporate a larger screᥱn which is a ϲhange thаt appеarѕ goіng to happen when the new i - Phone 5
is launcһed. The Blackberry Bold 9790 might not eclipse the Bold
9900 in some areas nonetɦeless it outshines its sіster model with regards to still photoցraphy.

One thing you ɦave tо remember before recoгding video iѕ tо
plаce the device horizontɑlly.

Quoting Seth:
Best calculator I've found. I'm overly active, I walk about 80,000 steps a day, excersize a few times a week. I needed to get my tdee to make sure I ate enough to keep from undereating. This is the only website I could find that could give me a an accurate estimate.

Correct me if I'm wrong. Wouldn't that be about 32 miles, assuming 2,500 steps per mile.

Quoting Kathleen DAntonio:
They did not leave a calculation for work .I also do that during a day....

If you are active at work, I.e. standing/walkin g around, use that dial. But if you have a desk job then it's assuming that you sit and automatically includes it.

Not even close to accurate. Says my BMR is 1900 cals doing nothing all day. I GAIN weight at 1900 cals. So yeah ...

Seconding the request for this to be translated into an app. It's a wonderful estimation tool!
#133 Claire 2017-01-17 14:10
For those of you who don't know how you can calculate the amount of calories needed to maintain your weight because no one really explains it here, use your BMR and multiply it by If you rarely exercise, multiply your BMR by 1.2 If you exercise on 1 to 3 days per week, by 1.375 If you exercise on 3 to 5 days per week, by 1.55 If you exercise 6 to 7 days per week, by 1.725 If you exercise every day and have a physical job or if you often exercise twice a day, multiply your BMR by 1.9

This was the only explanation I got online about how to calculate it.

Totally awesome! I would recommend this calc any day! Wish it was an app; or maybe it already is! Guess ill be searching for it via APP store! Great Work!
Stimulated and ready to change lives!!!

Is this calculator accurate?? It is giving me almost 800 calories more than the other TDEE calculators (at sedentary), which means I'm on ~1800 calorie deficit!? I put in:
- Sleep = 6 hours
- Light exercise 10 minutes
- Standing/Walkin g 30 minutes
So still pretty conservative on what I actually do every day.

My stats:
- Male
- 28
- 5ft 7in
- 206.6lbs
- Home office job
- Go gym 3 times a week (mostly lift for 40 minutes)
- Walking 2-3mph 3 times a week

Thank you, thank you, thank you. I've been hating myself because I couldn't lose trying to eat at 1500 cal a day. I kept binging up to 4k a day then feeling like the worst sort of failure. Not gaining, but not losing either, just a super yoyo on my food intake while I tried to exert control. This... I'm burning about 3000 calories a day. This makes so much more sense. I need to up my food intake and stabilize and *not* feel guilty about eating more than 2k calories daily, not beat myself up and feel like I'm just stupid.

Thank you.
