Understanding Calories and Energy Needs
What Are Calories?
Calories are a measure of energy. Your body uses calories from food to fuel:
Basal metabolism: Energy used at rest for essential body functions
Physical activity: Energy burned during exercise and daily movements
Thermic effect of food: Energy used to digest and process food
Basal Metabolic Rate (BMR)
BMR is the number of calories your body burns at rest. It depends on:
Age
Gender
Weight
Height
Total Daily Energy Expenditure (TDEE)
TDEE combines BMR with your activity level:
[
TDEE = BMR \times Activity\ Factor
]
Activity factors:
Sedentary (little or no exercise) = 1.2
Lightly active (light exercise 1–3 days/week) = 1.375
Moderately active (moderate exercise 3–5 days/week) = 1.55
Very active (hard exercise 6–7 days/week) = 1.725
Extra active (very hard exercise or physical job) = 1.9
Example Calorie Calculation
Scenario:
Age: 30
Gender: Female
Weight: 65 kg
Height: 165 cm
Activity Level: Moderately active
BMR (Mifflin-St Jeor formula):
[
BMR = 10 \times 65 + 6.25 \times 165 – 5 \times 30 – 161 = 1431\ \text{calories/day}
]
TDEE:
[
TDEE = 1431 \times 1.55 \approx 2218\ \text{calories/day to maintain weight}
]
For weight loss: ~1718 calories/day (-500 deficit)
For weight gain: ~2718 calories/day (+500 surplus)
