How accurate is a TDEE calculator?

TDEE calculators provide estimates based on proven formulas like Mifflin-St Jeor and Harris-Benedict. Individual results may vary by 10-20% depending on factors like muscle mass, genetics, and metabolism. Use the calculator as a starting point and adjust based on your actual results over 2-4 weeks.

What is the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is the number of calories your body burns at rest just to maintain vital functions. TDEE includes your BMR plus all calories burned through daily activities and exercise. TDEE = BMR × Activity Level Multiplier.

How many calories should I eat to lose weight?

To lose weight safely, eat 300-500 calories below your TDEE for a loss of 0.5-1 pound per week. Larger deficits (up to 1000 calories) can work for those with more weight to lose, but may lead to muscle loss and metabolic slowdown if sustained too long.

Should I adjust my TDEE as I lose weight?

Yes, as you lose weight, your TDEE decreases because you have less body mass to support. Recalculate your TDEE every 10-15 pounds of weight loss to ensure you continue making progress.

What is TDEE?

Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, including your Basal Metabolic Rate (BMR) and calories burned through physical activity.

Understanding your TDEE helps you set realistic calorie goals for weight loss, maintenance, or muscle gain.
