Healthy BMR 101: Calculate, Adjust, Transform
Ever wondered why one person thrives on 2,000 calories a day while another stalls out at the same intake? Your Basal Metabolic Rate — BMR — holds the clue. It's the calories your body burns at total rest just to keep your heart ticking, lungs working, and brain firing. No gym, no errands — pure survival mode.
A "healthy" BMR isn't one magic number. It's personal, shaped by age, sex, height, weight, and muscle. Women often range 1,300-1,700 calories; men 1,500-2,000. Athletes push higher thanks to muscle. Too low? Might signal hormone hiccups. Spot-on for your build? You're golden.
BMR Basics Without the Nerd Talk
Formulas like Mifflin-St Jeor make it simple: Men factor weight(kg)×10 + height(cm)×6.25 - age×5 + 5. Women swap the last to -161. A 5'7" gal, 140 lbs, 32 years old? Around 1,380. Quick, close enough for planning.
Muscle revs it up — pounds of lean mass mean extra burn 24/7. Age dings it 1-2% every decade. Genetics add flavor.
