Uma ungomunye walabo abakhetha ukudla izidlo ezintathu ezinkulu ngosuku (ibhulakufesi, isidlo sasemini nedina) esikhundleni sezinhlanu noma eziyisithupha ezincane, kufanele wazi ukuthi awunikeli i-metabolism sebenza ngokugcwele.
Futhi lapho imetabolism ihamba kancane, kushiswa amakhalori ambalwa ngakho-ke kunamathuba amaningi kakhulu okuthola isisindo. Ngakolunye uhlangothi, lapho senza izinto ukusheshisa, kuba lula bamba ulayini futhi ulahlekelwe amakhilogremu.
Abantu abenza amahlanu noma izidlo eziyisithupha okuncane nsuku zonke (ibhulakufesi, isidlo sasemini, isidlo sasemini, okulula nokudla kwakusihlwa) kwandisa isivinini semetabolism yakho kaningi kunalezo ezithi ngenxa yezikhathi noma ezinye izinkinga kudliwe kathathu kuphela.
Lokhu kungenxa yokuthi imetabolism idlula ngokusheshisa okuncane njalo lapho sidla, yingakho kulungile ukugcina umugqa futhi ulahlekelwe isisindo kuhlukanisa amakhalori esiwadingayo nsuku zonke ukungenwa kahlanu noma okuyisithupha.
Kumele kuqashelwe ukuthi, ngokusho kodokotela, umehluko ku- amakhalori ashile Phakathi kwabantu abadla kathathu nalabo abadla okuhlanu noma okuyisithupha kuncane, kepha uma uzama ukungakhuluphali kungaba usizo oluyisisekelo uma lo mkhuba uhlanganiswa nokunye njengokuzivocavoca okungenani kathathu ngeviki kanye nokufakwa ukudla okuvela kuwo wonke amaqembu ekudleni, okwaziwa njengokudla okulinganiselayo.
