Nezve iyi kalkulator
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.

Chii chinonzi Boer formula?
For men, LBM = 0.407 × weight(kg) + 0.267 × height(cm) − 19.2; for women, LBM = 0.252 × weight + 0.473 × height − 48.3. It predicts lean mass from height and weight and is one of the most accurate simple equations.
Nei chikafu chine mafuta chichikosha?
Inoita kuti urambe uchirara, uye kuongorora kuti uri kushaya mafuta kana kuti muviri, kunokubatsira kuti uzive kuti uri kushaya mafuta kana kuti muviri. Protein uye calorie zvinangwa zvinobva paLBM kana kuti muviri wose.
Chii chinonzi body fat percentage?

Chii chinonzi normal lean body mass?
Zvinoenderana nehukuru hwako uye nezera rako, asi kana uri 175 cm, 75 kg, Boer formula inokupa 58 kg yemuviri wakasviba uye 17 kg yemuviri wakasviba, kana kuti 23% yemuviri wakasviba. Vakadzi vane mafuta akakosha, saka huwandu hwavo hwemuviri wakasviba hunogona kunge huri pasi pehuwandu hwavo hwemuviri.
Ndeipi yakaderera-mafuta formula inofanira kushandiswa?
Boer ndiyo default uye yakanyatso ongororwa nevanhu vakawanda; James neHume vanoratidzwa kuti vaenzaniswe. Vachabvumirana zvakakwana pakuva nehuremu hwakanaka uye vanosiyana pavanenge vaine huremu hwakanyanya kana vanhu vane huremu hwakawanda.
Maitiro ekuwedzera muviri wemuviri?
Kushanda nesimba neproteini (inosvika 1.6-2.2 g/kg) uye nekudya zvakakwana kwekalori kunoumba miviri, iyo inonyanya kuumba muviri wakasviba. Kutevera LBM pakudya kunokubatsira kuti uone kuti uri kushaya mafuta asi kwete miviri.
Iine simba remuviri wemuviri imwechete semuscular mass?
Hapana. Lean body mass inosanganisira mishonga pamwe nenyama, maorgans, connective tissue uye muviri mvura; skeletal mishonga ndiyo chete chikamu chake. Muscle ndechimwe chikamu unogona kukwira nekudzidziswa.
