Understanding Your BMR in Phoenix
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions — breathing, circulation, cell production, and temperature regulation — while completely at rest. It typically accounts for 60–75% of total daily calorie expenditure.
Why Location Matters for Calorie Planning
Phoenix residents often shift workouts to early morning or evening to avoid summer heat — outdoor activity peaks October through April. If you live or work in Phoenix, understanding your BMR is the first step to setting accurate daily calorie targets. Use it as the foundation for TDEE, macros, and deficit calculations.
Mifflin-St Jeor Equation (Most Accurate)
Men: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5
Women: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) − 161
How to Use Your BMR
- Multiply BMR by an activity factor to get TDEE (Total Daily Energy Expenditure)
- Eat below TDEE to lose weight; above TDEE to gain weight
- BMR decreases with age — recalculate annually
