Ukudla kwe-keto kusalokhu kuyimpikiswano, naphezu kwalo lonke ucwaningo olukhona kulo. Abaningi bayisebenzisela ukunciphisa umzimba, kuyilapho abanye bekhetha ukunciphisa ukudla okunama-carbohydrate. Kuze kube manje, cishe akekho owayeke wazibuza ukuthi ngabe imiphumela izohluka yini kwabesilisa nabesifazane. Umehluko ukhona?
Ososayensi base-UC Riverside benze Ucwaningo ukuze ufunde ukuthi ukudla okudumile kwe-ketogenic kanye nokuzila ukudla okungapheli kusebenza kanjani ezingeni lamangqamuzana, nokuthi bobabili ubulili bayazuza yini kubo ngokulinganayo. Umqondo wokudla kwe-keto wukuthi amazinga aphansi ama-carbohydrates kanye namazinga aphezulu kakhulu amafutha namaprotheni azophoqa umzimba ukuthi usebenzise amafutha ukuze uthole uphethiloli, okuholela ekulahlekelweni kwesisindo.
Ngakolunye uhlangothi i ukuzila ukudla ngezikhathi ezithile isebenza ngesimiso esifanayo, esivimbela ukudla efasiteleni elincane lesikhathi phakathi nosuku. Phakathi namahora ngaphandle kokudla, umzimba uqeda izitolo zikashukela futhi uqala ukushisa amafutha. Amafutha aguqulwa abe yimizimba ye-ketone ubuchopho obungayisebenzisela uphethiloli.
Ingabe ihlukile kwabesifazane nabesilisa?
Naphezu kokuthandwa kwabo, ososayensi abakazihlonzi izakhi zofuzo noma amaprotheni avumela ukudla kusebenze. Ngakho lolu cwaningo olusha lucabanga ukuthi usuyazi ukuthi lusebenza kanjani. Isihluthulelo kungenzeka kube iphrotheni, ebizwa ngokuthi i-HNF4, etholakala emazingeni aphezulu esibindi. Kuyisici se-transcription, esiguqula i-DNA ibe i-RNA, bese iguqulwa ibe amaprotheni amasha, futhi iza ngezindlela ezimbili, i-P1 noma i-P2.
Ososayensi baqale baphenya i-P2 njengephrotheni ye-pro-cancer. Abazange bathole isixhumanisi somdlavuza, kodwa baqaphela ukuthi amagundane anamazinga aphezulu e-P2 esibindini sawo nawo abe nezakhi zofuzo ezihlukene zemetabolism. Baphinde bathola ukuthi i-P2 ibonakala ngamanani amakhulu kamuva ngosuku, okungachaza ukuthi kungani amagundane engazange athole isisindo esiningi uma isikhathi esidliwayo sivinjelwe; noma bedle kakhulu.
Kusolwa ukuthi i-enzyme ezwela amandla ingabangela ukushintshwa phakathi kwe-P1 ne-P2, engavumela inqubo yokushiswa kwamafutha ukuze uthole amandla. Kulolu cwaningo, ukunakwa okukhethekile kukhokhwe ezindleleni lapho amagundane abesilisa nabesifazane aphendula ngokudla kwe-ketogenic kanye nezikhathi ezithile.
Ukudla amafutha amaningi kwenza abesifazane bakhuluphale
Ukudla kwe-keto akubonakali kusebenza kahle kwabesifazane, ngoba Metabolise amafutha ngokuhlukile futhi sinezinhlobo ezahlukene zofuzo ezivuliwe futhi zivaliwe ekuphenduleni ukuzila ukudla. Kodwa asazi ngempela ukuthi kungani kwenzeka noma kanjani; yilokho esithemba ukukufunda.
Uma ukudla kusebenza kunoma yibuphi ubulili, abacwaningi bayakuxwayisa lokho Akukho ukudla okufanele kuthathwe ngokwedlulele. Akucaci ukuthi wonke amanoni enziwe nge-metabolism ekudleni kwe-keto noma ukuzila ukudla, noma uma inani elikhulu livele liqongelele emzimbeni. Izidlo zaseJapane ezijwayelekile ziqukethe amafutha angu-20%, ukudla kwaseMelika isilinganiso esingu-35%, futhi ukudla kwe-ketogenic kungaqukatha okungama-70 noma ama-80%, okungenzeka ukuthi inani eliphezulu kakhulu.
uma sidla namafutha, izosenza sikhuluphale ekugcineni. Njengokudla kakhulu noma yini kuzosenza sikhuluphele, kuhlanganise ne-zucchini. Okubaluleke kakhulu inani esikudlayo, esikudlayo nesikhathi sosuku.
