Common Questions Before Contacting Us
Quick answers to frequently asked questions
🔢 Why are my results different from other calculators?
Different calculators may use different formulas or activity multipliers. We use the Mifflin-St Jeor equation by default, which research shows is most accurate for most people. Variations of 100-200 calories between calculators are normal and expected.
📊 How accurate is the TDEE calculation?
TDEE calculators provide estimates typically within ±10-15% of actual values. Your real TDEE depends on individual factors like genetics, hormones, and body composition that formulas can't fully capture. Use the result as a starting point and adjust based on real-world results over 2-4 weeks.
💾 Is my data saved or stored?
No. All calculations happen directly in your browser. We don't send your personal information to any server, and we don't store any of your health data. If you save results, they're stored only on your device in local browser storage.
🏋️ Which activity level should I choose?
Be honest and, if unsure, choose one level lower than you think. Most people overestimate their activity level. "Sedentary" applies to most office workers, even if you exercise 3x/week. Check our calculator page for detailed descriptions of each level.
📉 How do I use TDEE for weight loss?
For weight loss, eat 300-500 calories below your TDEE for a sustainable rate of about 0.5kg (1lb) per week. Avoid going below your BMR. For personalized advice, please consult a registered dietitian—we can only provide general educational information.
🔄 How often should I recalculate?
Recalculate your TDEE when your weight changes by 5kg (10lbs) or more, when your activity level significantly changes, or every 4-6 weeks during active weight loss/gain. Your metabolic needs change as your body changes.
