Isibali Senqwaba Yomzimba Engenamafutha
Inqwaba yomzimba engenamafutha (LBM) yikho konke emzimbeni wakho ngaphandle kwamafutha — imisipha, amathambo, izitho zangaphakathi namanzi. Lesi sibali silinganisela i-LBM ngokusebenzisa isisindo sakho, ubude nobulili ngezilinganiso ezintathu eziqinisekisiwe (Boer, James no-Hume) bese sibonisa isilinganiso sazo kanye nenqwaba yamafutha ephumayo nephesenti lamafutha omzimba. Ukwazi i-LBM kusiza ukubeka imigomo ezwakalayo yamaprotheni namakhalori ngenkathi ulahla amafutha ngaphandle kokulahlekelwa imisipha.
Indlela yokusebenzisa le khalkhuletha ye-Lean Body Mass
Faka ubulili bakho, isisindo nobude (nephesenti lamafutha uma ithuluzi likucela) — ungashintsha phakathi kwe-metric ne-imperial — bese ucindezela ukubala. Isisindo sakho esingenamafutha sivela ngokushesha nge-kg noma i-lb, ngaphandle kokubhalisa.
Indlela yokufunda umphumela wakho
Isisindo esingenamafutha yingxenye yomzimba wakho engewona amafutha. Isisindo esingenamafutha esiphakeme ngesisindo esifanayo sisho imisipha eminingi. Ngesikhathi sokushisa amafutha, qaphela ukuthi isisindo esingenamafutha sihlale sizinzile ngenkathi isisindo sonke sehla.
Isayensi engemuva kwezinombolo
Isisindo esingenamafutha = isisindo − isisindo samafutha. Uma iphesenti lamafutha lingakalinganiswa, kusetshenziswa ifomula ye-Boer (amadoda 0.407×kg+0.267×cm−19.2; abesifazane 0.252×kg+0.473×cm−48.3). Isidingo se-protein ne-BMR kukhula ngokwesisindo esingenamafutha, okwenza le nombolo ibaluleke.
Imikhawulo namathiphu asebenzayo
Izilinganiso zefomula zihluke kwezilinganisiwe (DEXA/BIA), futhi izimo ezisemaphethelweni njengabazacile kakhulu, abakhuluphele noma abasubathi abade kakhulu ziyaphambuka. Sebenzisa iphesenti lamafutha elilinganisiwe ukuze kube nokunemba. Sebenzisa amakhalkhuletha e-CaloNote we-Body Fat, FFMI, Protein ne-BMR ndawonye, futhi ubhale intuthuko yakho ku-app ye-CaloNote.
Imibuzo Evame Ukubuzwa
- What is lean body mass?
- Lean body mass (LBM) is your total body weight minus fat mass, including muscle, bone, organs, and water. This calculator estimates it from your weight, height, and sex, and also reports your fat mass.
- Which lean body mass formula should I use?
- CaloNote shows the Boer, James, and Hume estimates so you can compare. The Boer formula is widely used and generally accurate for adults, while viewing all three gives a sensible range rather than relying on one equation.
- Why does lean body mass matter?
- LBM drives your resting metabolic rate and reflects how much muscle you carry, so tracking it helps ensure weight loss comes from fat rather than muscle. It is also used to set protein needs and calorie targets more precisely than weight alone.
