Worked Example: Daily Calorie Calculator (TDEE)
Given:
- weight = 70
- height = 175
- age = 30
- sex = 1
- activity = 3
- BMR (Mifflin-St Jeor) = 1648.75 kcal/day
- Activity factor for level 3 = 1.55
- Maintenance calories = 1648.75 × 1.55 = 2555.56 kcal/day
- Lose ~0.5 kg/week: 2056 kcal/day · lose ~0.25 kg/week: 2306 kcal/day
- Gain ~0.25 kg/week: 2806 kcal/day · gain ~0.5 kg/week: 3056 kcal/day
Answer: 2555.56
Frequently Asked Questions
What is the Daily Calorie Calculator (TDEE) formula?
TDEE = BMR × activity factor. Calories needed per day to maintain, lose or gain weight. Activity: 1 = sedentary, 2 = light, 3 = moderate, 4 = very active, 5 = athlete. Sex: 1 = male, 2 = female.
How do I calculate Daily Calorie Calculator (TDEE)?
Enter Weight (weight), Height (height), Age (age), Sex (1 = male, 2 = female) (sex), Activity Level (1–5) (activity) into the calculator. It applies TDEE = BMR × activity factor and shows every step of the working.
