How Katch-McArdle works in seconds: Enter lean body mass to compute BMR at 370 plus 21.6 per lean kilogram, then multiply by activity. Muscular builds get honest numbers weight formulas miss. Results appear at $0 cost in your browser.

Why lean mass wins for USA athletes on 09/22/2026: Two 200 lb lifters with different body fat burn differently — weight-only math blinds itself. Austin bodybuilders prepping $4,000 shows eat to lean-mass truth. Miami fighters cutting $8,000 camps preserve muscle with exact deficits.

Show prep: Peak-week carbs derive from true maintenance, not guesses. Chicago coaches programming $200 sessions adjust weekly as fat drops.

Contract shapes: New York models holding $80,000 contracts maintain within tight bands Katch-McArdle defines. Seattle climbers planning $5,000 pushes fuel lean mass specifically.

DEXA pairing: Feed scan-measured lean mass quarterly — estimates drift as composition shifts through training blocks.

Off-season blocks: Boston strongmen eating $6,000 mass phases set surpluses from lean-mass truth, not scale weight. Chicago figure coaches billing $250 peak-week consults adjust water and carbs precisely on 09/22/2026.

Swim seasons: Miami swimmers fueling $3,000 open-water campaigns eat to cold-water expenditure premiums. Denver firefighters maintaining $90,000 readiness standards hold body composition year-round.

Title camps: Phoenix boxers cutting $12,000 championship camps protect power with exact deficits. Refeed days derive from maintenance, never guesses.

Activity honesty: Desk-bound lifters differ wildly from trade workers — pick multipliers by total daily movement, not gym time alone.

DEXA cadence: Quarterly scans recalibrate lean mass as recomposition shifts numbers scales cannot see.

Strongman blocks: Boston strongmen eating $6,000 off-season mass phases set surpluses from lean-mass truth. Chicago figure coaches billing $250 peak-week consults adjust water and carbs precisely on 09/22/2026.

Swim fueling: Miami swimmers fueling $3,000 open-water campaigns eat to cold-water expenditure premiums. Denver firefighters maintaining $90,000 readiness standards hold composition year-round.

Title cuts: Phoenix boxers cutting $12,000 championship camps protect power with exact deficits. Refeed days derive from measured maintenance, never guesses.

DEXA cadence: Quarterly scans recalibrate lean mass as recomposition shifts numbers bathroom scales cannot see.
