How accurate is the TDEE calculation?

The Mifflin-St Jeor equation is considered the most accurate for most people, typically within 10% of actual energy expenditure. For the most accurate results, track your weight and calorie intake for 2-3 weeks and adjust based on real-world changes.

Should I eat my TDEE to maintain weight?

Yes, eating at your TDEE should maintain your current weight. For weight loss, eat 300-500 calories below TDEE. For muscle gain, eat 200-400 calories above TDEE. Start conservative and adjust based on weekly weight trends.

What activity level should I choose?

Be honest — most people overestimate their activity level. 'Sedentary' means desk job with no exercise. 'Lightly active' is 1-3 light workouts per week. 'Moderately active' is 3-5 moderate workouts. Only choose 'Very active' if you train intensely 6-7 days per week.

Why do men need more calories than women?

Men typically have more muscle mass and higher metabolic rates. The Mifflin-St Jeor formula accounts for this with a +5 adjustment for men and -161 for women. This results in roughly 200-400 more calories per day for men of similar size.
