Frequently Asked Questions

Total Daily Energy Expenditure (TDEE) is the total number of calories you burn per day, including your basal metabolic rate (BMR) and physical activity. It's the number of calories you need to maintain your current weight.

The Mifflin-St Jeor equation is considered the most accurate BMR formula. For males: BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age + 5. For females: BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age - 161.

For safe weight loss, eat 500 calories below your TDEE to lose about 1 pound per week. Never eat below 1,200 calories (women) or 1,500 calories (men) without medical supervision.

Recalculate every 10-15 pounds of weight change, or whenever your activity level changes significantly. As you lose weight, your TDEE decreases.
