What is a TDEE Calculator?
A TDEE Calculator estimates the total number of calories your body burns in a day, factoring in your Basal Metabolic Rate (BMR) and your daily activity level.
Are TDEE Calculators accurate?
They provide a useful estimate. Most calculators are typically accurate within about 10% if you honestly and correctly select your activity level. Individual metabolism varies, so it’s a starting point to be adjusted based on real-world results.
Which TDEE Calculator is best/most accurate?
The most commonly used and generally well-regarded is the one based on the Mifflin-St Jeor Equation. Some calculators also offer the Katch-McArdle Formula, which may be more accurate if you know your body fat percentage.
How do I use a TDEE Calculator?
You enter your personal data: age, gender, height, weight, and choose the category that best describes your weekly physical activity level.
How does a TDEE Calculator help with weight loss?
It estimates your maintenance calories. To lose weight, you must consistently consume fewer calories than your TDEE, creating a calorie deficit.
What is the difference between TDEE and BMR?
BMR (Basal Metabolic Rate) is the minimum calories your body burns at complete rest (for essential functions like breathing and circulation). TDEE (Total Daily Energy Expenditure) is your BMR plus the calories burned from all daily activities and exercise.
What is considered light exercise?
Typically defined as light activity or exercise 1-3 days per week, in addition to your normal daily activities.
What is considered moderate exercise?
Typically defined as moderate exercise or sports 3-5 days per week.
How do TDEE calculators factor in protein/macros?
The main TDEE calculation gives you a total calorie number. Some advanced calculators then use this number to provide suggested splits for your macronutrients (protein, carbs, and fat) based on your fitness goals.
