Frequently Asked Questions
What is BMR?
BMR (Basal Metabolic Rate) is the calories your body burns at rest for breathing, circulation, and cell function. Toolscal calculates BMR using the Mifflin-St Jeor equation: (10 × weight) + (6.25 × height) - (5 × age) + gender offset.
What is TDEE?
TDEE (Total Daily Energy Expenditure) is your BMR multiplied by your activity level. It represents all calories you burn daily, including exercise. Toolscal calculates TDEE to determine your calorie target for any goal.
How accurate is this calculator?
Toolscal uses the Mifflin-St Jeor equation, the most accurate formula (±10% error). Individual metabolism varies. Use calculated calories as a starting point, then adjust based on weight changes over 2-3 weeks.
How many calories to lose 1 kg per week?
To lose 1 kg per week, eat 1,000 calories below your TDEE daily (7,700 calorie deficit = 1 kg). Toolscal recommends 0.5-0.75 kg/week for sustainable, healthy weight loss.
Should I eat my BMR calories or TDEE calories?
Eat based on TDEE, not BMR. BMR is only rest calories. TDEE includes activity. Toolscal calculates your TDEE, then adjusts for your goal (lose/maintain/gain weight).
