Frequently Asked Questions
What is TDEE?
Total Daily Energy Expenditure is the total number of calories your body burns in a day. It includes your Basal Metabolic Rate (the energy you burn just being alive) plus calories burned through daily activity, exercise, and digesting food. It's the starting point for any weight management plan.
How accurate is this calculator?
This calculator uses the Mifflin-St Jeor equation, which research has shown to be the most accurate predictive formula for BMR (within 10% for most people). Your actual TDEE can vary based on genetics, body composition, stress, sleep, and other factors. Use this as a starting point and adjust based on real results over 2-3 weeks.
How many calories should I eat to lose weight?
A common guideline is to eat 500 calories below your TDEE, which creates a deficit that amounts to roughly 1 pound of fat loss per week. However, never go below 1,200 calories (women) or 1,500 calories (men) without talking to a doctor first. Sustainable weight loss is a marathon, not a sprint.
What's the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is the calories you'd burn lying in bed all day — just keeping your organs running. TDEE adds your actual daily movement and exercise on top of that. You should base your meal planning on TDEE, not BMR.
What does this have to do with Mealborne?
Mealborne is a gamified calorie tracker RPG where your TDEE becomes your daily "energy bar." Every meal you log is a battle encounter, and your Squire companion helps you stay on track by turning nutrition into an adventure. This calculator gives you the baseline your Squire uses to calibrate your quest.
