A lean body mass (LBM) calculator estimates the weight of everything in your body that is not fat — muscle, bone, organs and water — from your height, weight and sex. It uses the Boer formula by default, a well-validated prediction equation, with James and Hume as alternatives, and reports the remaining fat mass and body-fat percentage alongside it.
For a 175 cm, 75 kg man the Boer formula is 0.407 × 75 + 0.267 × 175 − 19.2 ≈ 58 kg of lean mass. Fat mass is then 75 − 58 = 17 kg, or about 23% body fat. Women use different constants (0.252 × weight + 0.473 × height − 48.3) because they carry proportionally more essential fat. The tool clamps results so lean mass never exceeds total weight.
Lean body mass is useful for setting protein and calorie targets, tracking whether a diet is costing you muscle, and, in medicine, for scaling some drug doses. Because these are prediction equations rather than a body scan, they are estimates — a DEXA scan or hydrostatic weighing is more precise for very lean or very heavy people. This is general information, not medical advice.
Mafunso ofunsidwa nthawi zambiri
Kodi ndi chiyani Boer formula?
Kwa amuna, LBM = 0.407 × kulemera (kg) + 0.267 × kukula (cm) - 19.2; kwa akazi, LBM = 0.252 × kulemera + 0.473 × kukula - 48.3.It amayembekezera lean maselo kuchokera kulemera ndi kukula ndi imodzi mwa zoyenera kwambiri zosawerengeka.
N'chifukwa chiyani thupi la thupi limakhudza?
Amakhazikitsa metabolism yanu yokhazikika komanso mankhwala osokoneza bongo m'maphunziro, ndipo kutsatira kwake kumakuthandizani kutsimikizira kuti mukuwononga mafuta osati minofu. Mapuloteni ndi ma calorie oyenera nthawi zambiri amapangidwa ndi LBM osati kulemera kwake kokwanira.
Kodi izi ndi zofanana ndi thupi-mafuta peresenti?
Ndi maziko awiri a mnda umodzi: mafuta masautso ndi kunenepa kwanu minus thupi labwino, ndi thupi-mafuta peresenti ndi mafuta masautso kugawidwa ndi kulemera kwa katundu.
Kodi ndi chiyani choyenera cha thupi la thupi?
Zimasiyana ndi kukula ndi kugonana, koma kwa 175 cm, 75 kg munthu Boer formula amapatsa pafupifupi 58 kg ya mafuta otsika ndi 17 kg ya mafuta, pafupifupi 23% ya mafuta a thupi. Akazi amayendetsa mafuta ambiri ofunikira, choncho kuchuluka kwa mafuta awo ndi kotsika pamtundu umodzi.
Kodi ndiyenera kugwiritsa ntchito formula ya maselo otsika?
Boer ndi default ndi bwino kuvomerezedwa kwa ambiri okalamba; James ndi Hume anasonyeza kwa kuyerekezera. Iwo akugwirizana kwambiri kwa maonekedwe apakati ndi kusiyanasiyana kwa anthu olemera kwambiri kapena olemera kwambiri.
Kodi ndingawonjezere bwanji thupi la thupi?
Kuphunzitsa kukana ndi mapuloteni okwanira (osadandaula 1.6-2.2 g / kg) ndi ma calories okwanira amaumba minofu, gawo lofunikira la maselo olemera. Kutsatira LBM nthawi ya chakudya kumakuthandizani kutsimikizira kuti mukuwononga mafuta osati minofu.
Kodi thupi la thupi ndilofanana ndi maselo a minofu?
Sichoncho. Lean body mass imaphatikizapo minofu komanso minofu, ma organoids, ma tiyi ogwirizana ndi madzi a thupi; minofu ya skeletal ndi gawo limodzi mwa magawo ake. Minofu ndi gawo lomwe mungawonjezere ndi kuphunzitsa.
