Articles about BMI / BMR / TDEE
BMI, BMR, and TDEE — with US clinical thresholds and macro guides.
For US readers, BMI uses the WHO standard cutoffs (overweight 25, obese 30), BMR uses Mifflin-St Jeor (1990), and TDEE multiplies by activity factor. We cover plateau-breaking with NEAT recovery, body-composition tools (Withings ±0.8%, Renpho ±2.3%, DEXA at 98% accuracy), and sarcopenia in older adults (PROT-AGE study group recommends 1.0–1.2 g/kg protein). Guides cite ACSM, NIH, and ESPEN where relevant.
