Our accurate TDEE calculator will work out your Total Daily Energy Expenditure. That's how many calories you burn every day. Atlas will also disply your Body Mass Index (BMI), Maximum Muscular Potential (MMP), Body Composition (Lean Mass VS Fat Mass), plus lots more useful data. Atlas, our intelligent health and fitness assistant can also help you with your personal goals, whether you want to lose weight, bulk up, or maintain your weight.
Our TDEE Calculator is designed to help you work out how many calories you burn every day. TDEE stands for Today Daily Energy Expenditure which is your BMR (or Basal Metabolic Rate) multiplied by your activity level. There are 5 levels of daily activity and 5 levels of exercise you can select which can accurately calculate within a margin of error how many calories you burn on an average day.
Atlas Says: When trying to lose weight/lose fat or bulk up/gain muscle you should use this TDEE Calculator regularly to maintain an accurate estimate of your daily calorie needs. As your weight increases or decreases, so too will the number of calories you need.
BMR (Basal Metabolic Rate) is the minimum amount of calories your body needs to stay alive at rest, whereas TDEE (Total Daily Energy Expenditure) is the amount of energy you burn doing your normal daily activities, including walking, working, and exercising. Your TDEE is, therefore, your BMR + activity.
Atlas Says: BMR essentially just shows how many calories your body needs to be alive as if you were in a coma. TDEE is your total number of calories required in a 24 hour period. Try our BMR Calculator to discover your Basal Metabolic Rate.
This tool breaks down activity levels into 2 parts: your job and your exercise. Each has 5 levels and when used together it can give you an accurate daily activity level. With exercise activity level from no exercising to exercising twice a day and job activity levels from a sedentary such as a desk job to extremely active like a farmer, you'll be able to find a combination that suits your needs.
Atlas Says: A fitness tracker will help you track more accurately how many calories you burn every day.
There are two formula's we use in this Total Daily Energy Expenditure Calculator, they are: Mifflin-St Jeor and Katch-McArdle. If you include body fat percentage then the calculator uses the accurate Katch-McArdle formula. However, if you do not add your body fat percentage, then the calculator falls back to using the Mifflin-St Jeor formula (which is still very accurate).
Mifflin-St Jeor Formula
Male = ( ( 10 x Weight in KGs ) + ( 6.25 x Height in CMs ) – ( 5 x Age ) + 5 ) x Activity Level
Female = ( ( 10 x Weight in KGs ) + ( 6.25 x Height in CMs ) – ( 5 x Age ) - 161 ) x Activity Level
Male & Female = ( 370 + ( 21.6 x ( Weight in KGs - (Body Fat % x Weight in KGs) ) ) ) x Activity Level
Atlas Says: These formulas give an estimation of the number of calories you burn every day. It's best to say that there is a margin of error of 10%, so regularly check and tweak to provide better results.
There are 3 goals available as part of this calculator. Lose fat, maintain, and gain muscle. Each option alters the calorie opt out. Maintain is your TDEE calories as is, lose fat is 80% of your TDEE calories, and gain muscle is 120%.
Atlas Says: A goal is a rough rule of thumb to help you understand how many calories you need to lose, maintain, or gain weight.
This TDEE Calculator works out your TDEE (Total Daily Energy Expenditure) calories, BMR (Basal Metabolic Rate) calories, full calorie chart for all 25 activity level combinations, BMI (Body Mass Index) score, MMP (Maximum Muscular Potential) weight, and your Body Composition stats (Lean Mass VS Fat Mass).
