You've probably heard the term "calories".
And maybe TDEE.
But when it comes to how much calories you need per day to maintain what you've got, it's all about TDEE - Total Daily Energy Expenditure.
This is the total number of calories your body needs to function in a day, including basic bodily functions and physical activities.
Understanding your TDEE is crucial to managing your weight and achieving your fitness goals.
Here's a calculator you can use to figure out your TDEE:
TDEE stands for Total Daily Energy Expenditure. It's the total number of calories your body needs to perform daily activities. Understanding your TDEE is crucial for managing your weight and achieving your fitness goals.
How is TDEE calculated?
TDEE is calculated based on your Basal Metabolic Rate (BMR), Physical Activity Level (PAL), and the Thermic Effect of Food (TEF). Some calculators also consider body fat percentage and lean body mass.
How can I use my TDEE to lose weight or gain muscle?
Once you know your TDEE, you can create a calorie deficit to lose weight or a calorie surplus to gain muscle. This means eating fewer or more calories than your TDEE, respectively.
Are TDEE calculators accurate?
TDEE calculators provide an estimate of your daily caloric needs. The accuracy of this estimate depends on the accuracy of the information you provide.
So, what exactly is a TDEE calculator? It's a tool that calculates your Total Daily Energy Expenditure - the total number of calories your body needs to perform daily activities.
This includes everything from breathing and circulating blood, to digesting food and exercising.
The calculator takes into account your Basal Metabolic Rate (BMR), Physical Activity Level (PAL), and the Thermic Effect of Food (TEF) to provide an accurate estimate of your TDEE.
Benefits of Using a TDEE Calculator
Now, you might be wondering - why should I use a TDEE calculator?
The answer lies in the problem of inaccurate calorie counting.
Many people underestimate the number of calories they consume and overestimate the number they burn through exercise.
This can lead to weight gain and frustration.
A TDEE calculator provides a solution to this problem by giving you an accurate estimate of your daily caloric needs.
Understanding the Nutritional Facts and Ingredients of a TDEE Calculator
A TDEE calculator isn't a physical product with nutritional facts and ingredients. Instead, it's a tool that uses specific inputs to calculate your TDEE. These inputs include your age, gender, weight, height, and physical activity level.
Some calculators also consider body fat percentage and lean body mass. By understanding these "ingredients", you can ensure you're providing accurate information for the most precise TDEE calculation.
The Science Behind TDEE Calculators
TDEE calculators are based on scientific research and formulas. These formulas consider your BMR (the number of calories your body needs to perform basic functions), your PAL (the number of calories your body uses for activities), and TEF (the number of calories your body uses to digest food).
By combining these factors, TDEE calculators can provide an accurate estimate of your daily caloric needs.
How to Use a TDEE Calculator
Using a TDEE calculator is simple. Here's a step-by-step guide:
- Enter your age, gender, weight, and height.
- Select your physical activity level.
- If the calculator allows, enter your body fat percentage and lean body mass.
- Click "Calculate" to get your TDEE.
Remember, the more accurate the information you provide, the more accurate your TDEE calculation will be.

FAQs
The Mifflin-St Jeor equation is recommended by the American Council on Exercise as an accurate method for calculating Total Daily Energy Expenditure (TDEE). This equation includes considerations for basal metabolic rate and an activity multiplier, providing an individualized estimate of TDEE.
How do I calculate my body calorie requirements? ›
If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2. If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375. If you are moderately active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55.
How many calories should I eat based on TDEE? ›
To lose weight, aim to consume 10-20% fewer calories than your TDEE. For example, if your TDEE is 2,000 calories, you might aim for a daily intake of 1,600 to 1,800 calories.
What is the most trusted calorie calculator? ›
FAQ #1: What is the best calorie calculator? If you don't know your body fat percentage, the Mifflin-St Jeor calorie calculator equation tends to produce the most accurate results. If you know your body fat percentage, the Katch-McArdle equation is the most accurate.
Does walking count as exercise in TDEE? ›
That activity can be exercise in the form of workouts at the gym, yoga, pilates, or running. That activity can also be walking, cleaning, or playing with your kids in the park. The TDEE requires you to include your activity level - and that activity can be anything that requires you to move around.
How do I manually calculate my TDEE? ›
Calculating TDEE using the formula TDEE = BMR x Activity Factor involves two steps:
- Step 1: Calculate your BMR using the following formula. BMR = 10 x weight (kg) + 6.25 x height (cm) - 5 x age (years) + 5. ...
- Step 2: Multiply your BMR by your activity factor to calculate your TDEE.
In order to lose at least a pound a week, try to do at least 30 minutes of physical activity on most days, and reduce your daily calorie intake by at least 500 calories. However, calorie intake should not fall below 1,200 a day in women or 1,500 a day in men, except under the supervision of a health professional.
How do I calculate calories in my daily diet? ›
A gram of carbohydrates also has 4, and a gram of fat is worth a whopping 9 calories. If the item you're eating contains 20g of protein, 35g of carbs, and 15g of fat, this means you would multiply 20x4, 35x4, and 15x9 to find the number of calories contributed by each macronutrient—80, 140, and 135, respectively.
What is the 1500 calorie rule? ›
A good rule of thumb for healthy weight loss is a deficit of about 500 calories per day. That should put you on course to lose about 1 pound per week. This is based on a starting point of at least 1,200 to 1,500 calories a day for women and 1,500 to 1,800 calories a day for men.
How do I work out my TDEE calorie deficit? ›
Since you're moderately active, you will use an activity factor of 1.55. Therefore, your TDEE is 2,170 calories (1,400 x 1.55). This means your body burns around 2,170 calories per day, including your BMR and physical activity. To create a healthy calorie deficit, you can subtract 300 to 500 calories from your TDEE.
Generally to lose 1 to 2 pounds a week, you need to burn 500 to 1,000 calories more than you consume each day, through a lower calorie diet and regular physical activity. Depending on your weight, 5% of your current weight may be a realistic goal, at least for an initial goal.
What is the difference between a calorie calculator and a TDEE calculator? ›
On the other hand, a Total Daily Energy Expenditure (TDEE) calculator estimates the total calories you burn in a day, including your basal metabolic rate and physical activity. While a calorie counter focuses on intake, a TDEE calculator provides a broader picture of your energy needs.
How can I calculate my calories to lose weight? ›
How many calories should I deficit to lose weight?
