What is TDEE and how is it calculated?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day. It is calculated by multiplying your Basal Metabolic Rate (BMR) by an activity factor that reflects your physical activity level. TDEE includes all energy used for basic body functions, digestion, and physical activity.

How accurate are TDEE calculators?

TDEE calculators provide estimates based on established formulas (like Mifflin-St Jeor or Harris-Benedict). Individual results may vary by 10-15% due to factors like genetics, metabolism, muscle mass, and hormones. The best way to verify accuracy is to track your intake and weight over 2-3 weeks and adjust accordingly.

How should I use my TDEE for weight loss or gain?

For weight loss, consume 300-500 calories below your TDEE for sustainable fat loss (about 0.5-1 lb per week). For weight gain, add 300-500 calories above TDEE for healthy muscle gain. For maintenance, eat at your TDEE level. Always prioritize protein intake and adjust based on your progress.
