Daily Calorie Needs (Goal Based)

The table below shows how calorie intake changes based on your fitness goal.

GoalDescriptionRecommended Calories
Weight LossReduce calorie intake to create a healthy fat-loss deficit.TDEE – 300 to 500 kcal
Maintain WeightKeep your current body weight stable.Equal to TDEE
Weight GainIncrease calories to support muscle and weight gain.TDEE + 300 to 500 kcal

How Calorie Calculation Works

Your daily calorie needs depend on two main metrics:

1. BMR (Basal Metabolic Rate)

BMR is the number of calories your body needs at rest — this keeps your heart beating, lungs breathing, and organs functioning. We use the scientifically proven Mifflin-St Jeor formula for high accuracy.

2. TDEE (Total Daily Energy Expenditure)

TDEE is your BMR multiplied by your activity level. This shows the total calories you burn daily.

Calorie Needs for Goals

  • Weight Loss: Eat 300–500 calories less than your TDEE.
  • Weight Gain: Eat 300–500 calories more than your TDEE.
  • Maintenance: Eat your TDEE calories.
