If you’ve ever wondered how many calories you should eat to lose, maintain, or gain weight, the answer lies in your TDEE (Total Daily Energy Expenditure).
TDEE is the total number of calories your body burns in a day, including:
- BMR (Basal Metabolic Rate) – energy used for basic functions like breathing and circulation.
- Activity Level – calories burned from exercise and daily movement.
- Thermic Effect of Food (TEF) – calories burned during digestion.
The Best TDEE Calculator helps you estimate this number instantly, so you can plan your nutrition and fitness goals more effectively.
How to Use the Best TDEE Calculator (Step-by-Step)
- Enter Your Age, Gender, Height, and Weight
- These determine your BMR.
- Select Activity Level
- Options usually include:
- Sedentary (little/no exercise)
- Lightly active (1–3 workouts/week)
- Moderately active (3–5 workouts/week)
- Very active (6–7 workouts/week)
- Extra active (intense training/physical job)
- Options usually include:
- Click “Calculate”
- The tool instantly gives you your TDEE in calories/day.
- Adjust for Goals
- To lose weight → Eat fewer calories than your TDEE.
- To gain weight → Eat more calories than your TDEE.
- To maintain → Eat close to your TDEE.
Practical Example
Let’s say you are:
- Age: 28
- Gender: Male
- Height: 5’10” (178 cm)
- Weight: 75 kg (165 lbs)
- Activity Level: Moderately active
Result:
- BMR: ~1,750 calories/day
- TDEE: ~2,650 calories/day
👉 This means you need about 2,650 calories daily to maintain your weight.
- To lose fat → Eat ~2,150 calories/day
- To gain muscle → Eat ~3,150 calories/day
