Unezifiso? Ucwaningo olusha luphakamisa ukuthi imikhuba yethu yokuthwebula kanye ne-Body Mass Index ayihlobene nje nendlala. Esikhundleni salokho, zinokuningi okuphathelene nomsebenzi wethu wobuchopho nokuzithiba.

Lolu cwaningo luzovela kumagazini u-Okthoba NeuroImage, ibandakanye abesifazane abancane abangama-25, abanempilo enama-BMIs kusuka ku-17 kuye ku-30 ​​(Abaphenyi bakhethe ukuhlola abesifazane ngoba ngokuvamile bayaphendula kakhulu kunamadoda ezinkomba ezihlobene nokudla). Ngemuva kokungadli amahora ayisithupha, abesifazane babheka izithombe zezinto zasendlini nezinto ezahlukahlukene zokudla, ngenkathi ukuskena kwe-MRI kuqopha umsebenzi wabo wobuchopho. Abacwaningi bacele abesifazane ukuthi balinganisele ukuthi bafuna malini ukudla abakubonayo nokuthi balambile kangakanani, base benikeza ababambiqhaza izitsha ezinkulu zamashibhisi amazambane futhi babale ukuthi bangaki abangene emlonyeni wabo.

Imiphumela ikhombise ukuthi okwenziwa kuma-nucleus accumbens, okuyingxenye yobuchopho ehambisana nokugqugquzela kanye nomvuzo, kungabikezela inani lamachips abesifazane abadlayo. Ngamanye amagama, lapho umsebenzi ubukhona kule ngxenye yobuchopho, ama-chips amaningi abesifazane abawadlayo.

Futhi mhlawumbe isimanga esikhulu kunazo zonke: Inani lama-chips abesifazane abawadlayo lalingahlobene nhlobo nemizwa yabo ebikiwe yokulamba noma ukulangazelela ukudla okulula. Esikhundleni salokho, ukuzithiba (njengoba kukalwa ngohlu lwemibuzo lokuhlolwa kwangaphambili) kwakuhlobene kakhulu nokuthi kungakanani abesifazane abashwabezelayo abakwenzile. Phakathi kwabesifazane abanobuchopho obukhanyayo ngenxa yezithombe zokudla, labo abanokuzithiba okuphezulu bavame ukuba nama-BMIs aphansi kanti labo abanokuzithiba okuphansi ngokuvamile babene-BMIs ephezulu.

UDkt. John Parkinson, uthisha omkhulu kwezokusebenza kwengqondo e-University of Bangor futhi ongomunye wababhali bocwaningo, uthe imiphumela ilingisa lokho okuvame ukwenzeka empilweni yangempela. "Ngandlela thize lena isenzakalo sakudala sephathi ye-buffet lapho uzitshela ukuthi akufanele uzitika ngokudla okulula okumnandi, kodwa "awukwazi ukuzibamba" futhi ugcine uzizwa unecala," ebhala ku-imeyili.

Imiphumela evela ocwaningweni isekela olunye ucwaningo oluphakamisa ukuthi abantu abathile bazwela kakhulu lapho bebona ukudla ngakho-ke kungenzeka ukuthi bakhuluphele (nakuba kungakacaci ukuthi impendulo yethu yobuchopho ezithombeni zokudla ifundiwe yini noma izalwa). Manje abacwaningi basebenza ezinhlelweni zekhompiyutha ezizosiza ukuqeqesha ubuchopho bethu ukuba buphendule ngendlela ehlukile ekudleni. Ngakho-ke, ngokufanele, imigoqo ye-Snickers izobukeka ingakhangi kangako futhi kuzoba lula kubasebenzisi ukugcina isisindo esinempilo.

Ukuthola okwengeziwe ngendlela ubuchopho bethu obuthonya ngayo imikhuba yethu yokudla, ososayensi futhi kudingeka bacabangele abanye abantu ngaphandle kwabesifazane abasebasha, abaphilile. Umcwaningi oholayo uDkt.Natalia Lawrence, umfundisi ophakeme kwezokusebenza kwengqondo e-University of Exeter, ubalule amanye amathuba ocwaningo oluzayo. "Kungajabulisa ukufunda iqembu lama-bulimics ane-BMI ephansi kanye nokuzithiba okuphansi; kungenzeka ukuthi bahlanganyela nezinye (isb. izinxephezelo) izindlela ezifana nokusebenza kakhulu noma ukugwema isilingo kwasekuqaleni," wabhala ku-imeyili.

Kuningi okusamele kufundwe mayelana nobudlelwano phakathi kobuchopho nendlela odla ngayo. Njengamanje abacwaningi abakaqiniseki ukuthi izindlela ezahlukene zokuqeqesha ubuchopho zizothinta kanjani ukuzithiba kwethu kanye nezifiso zokudla. Kwazi bani? Mhlawumbe maduze sizosebenzisa amakhono ethu e-Tetris ukusiza ukugcina isisindo sethu siphansi.

Ungazama ukudlala uhlelo lwekhompiyutha ukuze ulawule isisindo sakho? Sazise kumazwana angezansi.
