Calorie Intake Calculator
What is a Calorie Intake Calculator?
A calorie intake calculator helps estimate the number of calories your body needs each day to maintain, lose, or gain weight.
The calculation is based on factors such as:
- Age
- Gender
- Height
- Weight
- Physical activity level
Knowing your daily calorie requirement can help you create healthier eating habits and fitness plans.
How Does This Calorie Calculator Work?
This calculator first estimates your Basal Metabolic Rate (BMR), which is the number of calories your body burns at rest.
It then applies an activity multiplier to calculate your Total Daily Energy Expenditure (TDEE).
Formula Used
TDEE=BMR×Activity FactorTDEE = BMR \times Activity\ FactorTDEE=BMR×Activity Factor
This helps estimate your daily calorie needs depending on your lifestyle and activity level.
Daily Calories for Weight Loss
To lose weight, calorie intake generally needs to be lower than the number of calories burned daily. A moderate calorie deficit combined with regular exercise may support healthy weight loss.
Daily Calories for Weight Gain
For healthy weight gain or muscle building, calorie intake usually needs to exceed maintenance calories along with strength training and adequate protein intake.
Daily Calories for Weight Maintenance
Maintaining weight generally requires balancing calorie intake with calories burned through metabolism and physical activity.
| Activity Level | Description |
|---|---|
| Sedentary | Little or no exercise |
| Lightly Active | Exercise 1–3 days/week |
| Moderately Active | Exercise 3–5 days/week |
| Very Active | Intense exercise 6–7 days/week |
| Extra Active | Physically demanding lifestyle |
