Abstract
UMGQUBO:
Ukutyeba ngokugqithiseleyo ngubhubhani wezempilo wale mihla, kunye nokutyiwa okugqithisileyo kokutya okunencasa kakhulu, okunekhalori exineneyo njengegalelo elinokubakho. Ngaphandle kweziphumo ezaziwayo zokutyeba, ukungathotyelwa kokuziphatha kuhlala kuphezulu, kuxhasa iipropathi ezinamandla ezinomvuzo wokutya okunjalo. Siye sacinga ukuba ukuvezwa kwizidlo ezikhethiweyo kuya kubangela ukuphuculwa kokuphendula koxinzelelo ngokuvula iindlela zomvuzo ezinokuthi zitshintshwe ngexesha lokurhoxiswa kokutya, ukonyusa umngcipheko wokuphinda ubuyele kunye nokusilela kunyango.
IINDLELA:
Iigundane zavezwa kwizidlo ezikhethiweyo eziphezulu kwi-fat okanye i-carbohydrates kwiiveki ze-4 kwaye emva koko zihoxiswa kwi-chow yendlu. Ukuziphatha, i-physiologic, kunye novavanyo lwe-biochemical lwenziwa ukuhlola utshintsho kuxinzelelo kunye neendlela zomvuzo.
IINKCUKACHA:
Ezi zifundo zibonise utshintsho olubalulekileyo kwindlela yokuziphatha evuselelayo kunye nexhala, i-limbic corticotropin-releasing factor expression, kunye nokubonakaliswa kweemolekyuli ezinxulumene nomvuzo ekuphenduleni ukutya okunamafutha aphezulu okuthandwa kakhulu okuye kwatshintshwa kukurhoxiswa. Kwimodeli yokubuyisela ukutya, iimpuku eziye zarhoxiswa ekutyeni okunamafutha aphezulu ziye zanyamezela imeko-bume ephazamisayo ukuze zifikelele ekutyeni okukhethiweyo.
IMISEBENZI:
Ukuvezwa kokutya okuthandwa kakhulu kunamafutha aphezulu kunciphisa ubuntununtunu boxinzelelo, ngelixa ukurhoxa ngokungxamisekileyo kukutya okunjalo kuphakamisa imeko yoxinzelelo kwaye kunciphisa umvuzo, kube negalelo kuqhubo lokubuyela ekutyeni.
