🔥 What’s BMR?
BMR (Basal Metabolic Rate) estimates how many calories your body uses at rest to support essential functions such as breathing and circulation.
We use the Mifflin-St Jeor formula —a widely used method that generally provides a more accurate estimate for adults than the older Harris-Benedict equation.
🏃♂️What’s TDEE?
TDEE (Total Daily Energy Expenditure) estimates how many calories you use each day by combining your BMR with energy spent on activities such as walking, working, and exercising.
🎯 Daily Calorie Target Adjusted for Your Goal
We adjust your estimated TDEE based on your selected goal—weight loss, muscle gain, or maintenance—to provide a personalized daily calorie target.
Use this estimate as a practical starting point for planning your daily intake.
The minimum daily calorie intake—1,200 calories for adult women and 1,500 for adult men—is based on recommendations from the U.S. National Library of Medicine’s MedlinePlus , Taiwan’s Ministry of Health and Welfare , and other health authorities.
