I-Ketosis yisimo semvelo semethabolic.

Kubandakanya umzimba ukukhiqiza imizimba ye-ketone emafutheni bese uyisebenzisela amandla esikhundleni se-carbs. Ungangena ku-ketosis ngokulandela i-carb ephansi kakhulu, ukudla okunamafutha aphezulu ketogenic ().

Ukudla okune-ketogenic kungakusiza ulahlekelwe isisindo. Esikhathini esifushane, ungalahlekelwa isisindo ngokushesha, ngoba kunciphisa izitolo zomzimba ze-glycogen namanzi.

Ngokuhamba kwesikhathi, ingavimbela isifiso sakho sokudla esiholele ekutholeni ikhalori eliphansi.

Kanye nokunikela ekwehliseni isisindo, i-ketosis ingaba nezinzuzo eziningana zezempilo, njengokuncipha kokuquleka ezinganeni ezinesithuthwane ().

I-ketosis iyinkimbinkimbi impela, kepha le ndatshana ichaza ukuthi iyini nokuthi ingakusiza kanjani.

Yini i-ketosis?

I-Ketosis yisimo se-metabolic lapho kunokuxinana okuphezulu kwamaketoni egazini. Lokhu kwenzeka lapho amafutha ehlinzeka ngophethiloli omningi womzimba, futhi kunokufinyelela okulinganiselwe kushukela. Iglucose (ushukela wegazi) ngumthombo kaphethiloli owuthandayo wamaseli amaningi emzimbeni.

I-ketosis ivame ukuhlotshaniswa nokudla kwe-ketogenic futhi okuphansi kakhulu kwe-carb. Kuyenzeka futhi ngesikhathi sokukhulelwa, usana, ukuzila ukudla nendlala (,,,).

Ukuze i-ketosis iqale, ngokuvamile udinga ukudla ama-gramu angaphansi kwama-50 we-carbs ngosuku futhi kwesinye isikhathi kube ngama-gramu angama-20 ngosuku. Kodwa-ke, ukudla ngqo kwe-carb okuzobangela i-ketosis kuyahlukahluka phakathi kwabantu.

Ukwenza lokhu, kungadingeka ukuthi ususe izinto ezithile zokudla ekudleni kwakho, njenge:

• okusanhlamvu
• uswidi
• iziphuzo ezinoshukela

Futhi kufanele unciphise:

• imidumba
• amazambane
• izithelo

Lapho udla ukudla okuphansi kakhulu kwe-carb, amazinga e-hormone insulin ayahla futhi ama-fatty acids akhishwa ezitolo ezinamafutha omzimba ngamanani amakhulu.

Iningi lalawa mafutha acid ayiswa esibindini, lapho axutshwa khona aguqulwe abe ngamaketoni (noma imizimba ye-ketone). Lezi zinhlayiya zinganikeza amandla omzimba.

Ngokungafani nama-acid okunamafutha, amaketoni angawela umgoqo wegazi nobuchopho futhi anikeze amandla obuchopho uma ingekho i-glucose.

I-Ketosis yisimo se-metabolic lapho amaketoni eba umthombo obalulekile wamandla omzimba nobuchopho. Lokhu kwenzeka lapho amazinga we-carb kanye ne-insulin ephansi.

Ama-ketone anganikeza amandla obuchopho

Kuyinto engaqondakali evamile ukuthi ubuchopho abusebenzi ngaphandle kwama-carbs wokudla.

Kuyiqiniso ukuthi i-glucose iyathandwa nokuthi amanye amaseli ebuchosheni angasebenzisa i-glucose kuphela njengophethiloli.

Kodwa-ke, ingxenye enkulu yobuchopho bakho ingasebenzisa futhi ama-ketone amandla, njengalapho kubulawa indlala noma lapho ukudla kwakho kuphansi kuma-carbs ().

Eqinisweni, ngemuva kwezinsuku ezintathu kuphela zendlala, ubuchopho buthola amandla ayo angama-25% kuma-ketone. Ngesikhathi sendlala yesikhathi eside, le nombolo inyukela kuma-60% (,).

Ngaphezu kwalokho, umzimba wakho ungasebenzisa amaprotheni noma amanye ama-molecule ukukhiqiza i-glucose ubuchopho obusayidinga ngesikhathi se-ketosis. Le nqubo ibizwa ngokuthi i-gluconeogenesis.

I-Ketosis ne-gluconeogenesis zikwazi ngokuphelele ukufeza izidingo zamandla obuchopho.

Nalu ulwazi oluthe xaxa mayelana nokudla okune-ketogenic kanye nobuchopho: Ukuthi i-Low-Carb kanye ne-Ketogenic Diet Kukhulisa kanjani i-Brain Health.

Lapho ubuchopho bungatholi i-glucose eyanele, ingasebenzisa amaketoni ukuthola amandla. I-glucose esayidinga ingakhiqizwa kusuka kumaprotheni noma eminye imithombo.

I-ketosis ayifani ne-ketoacidosis

Abantu bavame ukudida i-ketosis ne-ketoacidosis.

Ngenkathi i-ketosis iyingxenye yemetabolism ejwayelekile, i-ketoacidosis yisimo esiyingozi semetabolism esingaba yingozi uma singalashwa.

Ku-ketoacidosis, ukugeleza kwegazi kugcwala ngokweqile amazinga aphezulu eglucose (ushukela egazini) namaketoni.

Uma lokhu kwenzeka, igazi liba ne-asidi, okuyingozi enkulu.

I-Ketoacidosis ivame ukuhlotshaniswa nohlobo 1 lwesifo sikashukela esingalawulwa. Kungenzeka futhi kubantu abane-type 2 yesifo sikashukela, yize lokhu kungavamile ().

Ngaphezu kwalokho, ukusebenzisa kabi utshwala ngokweqile kungaholela ku-ketoacidosis ().

I-Ketosis yisimo semvelo semetabolic, kuyilapho i-ketoacidosis iyisimo esibucayi sezokwelapha esivame ukubonwa kuhlobo 1 lwesifo sikashukela esingalawulwa kahle.

Imiphumela yesithuthwane

Isithuthwane ukuphazamiseka kwengqondo okubonakala ngokuquleka okuphindelela.

Isimo esivame kakhulu sezinzwa, esithinta abantu abangaba yizigidi ezingama-70 emhlabeni jikelele ().

Iningi labantu abanesithuthwane basebenzisa imishanguzo yokulwa nokuquleka ukusiza ukuphatha ukuquleka. Kodwa-ke, cishe abantu abangama-30% bayaqhubeka nokuhlaselwa yize besebenzisa le mithi ().

Ngasekuqaleni kwawo-1920, ukudla okwe-ketogenic kwethulwa njengokwelashwa kwesifo sokuwa kubantu abangaphenduli ekwelashweni kwezidakamizwa ().

Isetshenziswe ikakhulu ezinganeni, ezinye izifundo zibonisa izinzuzo. Izingane eziningi ezinesithuthwane zikubonile ukuncipha okukhulu kokuquleka ngenkathi zilandela ukudla okune-ketogenic, kanti ezinye zibone ukuxolelwa okuphelele (,,,).

Ukudla kwe-Ketogenic kunganciphisa ngempumelelo ukuquleka kwesithuthwane, ikakhulukazi ezinganeni ezinesithuthwane ezingaphenduli ekwelashweni okuvamile.

Imiphumela ekulahlekelweni kwesisindo

Ukudla kwe-ketogenic kungukudla okudumile kokunciphisa umzimba, futhi ucwaningo lukhombisile ukuthi lungasebenza ().

Ezinye izifundo zithole ukuthi izidlo ze-ketogenic zisiza kakhulu ekunciphiseni isisindo kunokudla okunamafutha aphansi (,,).

Olunye ucwaningo lubike ukulahleka kwesisindo okuphindwe izikhathi ezingu-2.2 kubantu abadla i-ketogenic, uma kuqhathaniswa nalabo abanamafutha aphansi, ukudla okunomkhawulo wekhalori ().

Ngaphezu kwalokho, abantu bavame ukuzizwa belambile futhi begcwele kakhulu ekudleni kwe-ketogenic, okubangelwa yi-ketosis. Ngalesi sizathu, ngokuvamile akudingekile ukubala amakhalori kulokhu kudla (,).

Kodwa-ke, kwaziwa kabanzi ukuthi ukunamathela ekudleni kubalulekile empumelelweni yesikhathi eside. Abanye abantu bangakuthola kulula ukunamathela ekudleni kwe-ketogenic, kanti abanye bangakuthola kungasimami.

Olunye ucwaningo lukhombisa ukuthi ukudla keto kungenzeka kungabi yindlela engcono yokwehlisa isisindo. Ababhali besibuyekezo se-2019 baphethe ngokuthi bekungcono kunezinye izidlo ekusizeni abantu banciphise isisindo, futhi kungahle kungabi nezinzuzo ezithile kubantu abanenkinga yokuhleleka komzimba (26).

Imininingwane eminingi lapha: Ukudla kwe-Ketogenic Ukwehlisa Isisindo Nokulwa Nezifo.

Ezinye izifundo zibonisa ukuthi izidlo ze-ketogenic ziholela ekulahlekelweni kwesisindo esiningi kunokudla okunamafutha aphansi. Ngaphezu kwalokho, abantu bazizwa belambile futhi besuthe ngokwengeziwe.

Ezinye izinzuzo zezempilo ze-ketosis

Abanye ososayensi baphakamise ukuthi ukudla okune-ketosis kanye ne-ketogenic kungahle kube neminye imiphumela yokwelapha, yize kubalulekile ukuthi uqaphele ukuthi akubona bonke ochwepheshe abavumelana ngalokhu (, 26).

• Isifo senhliziyo: Olunye ucwaningo oludala lukhombisa ukuthi ukunciphisa ama-carbs ukufeza i-ketosis kungathuthukisa izifo eziyingozi ezinjenge-triglycerides yegazi, i-cholesterol ephelele, ne-HDL cholesterol. Kodwa-ke, ukubuyekezwa kwe-2019 kuphawula ukuthi abantu abanokudla okuphansi kakhulu kwe-carb bangaphuthelwa ukudla okunempilo yenhliziyo, njengokusanhlamvu okuphelele kanye nokudla okugayiwe (26,,).
• Thayipha 2 sikashukela: Ukudla kungathuthukisa ukuzwela kwe-insulin nezici ezahlukahlukene zobungozi ezingadala uhlobo lwesifo sikashukela sohlobo lwe-2, kufaka phakathi ukukhuluphala (,,).
• Isifo sikaParkinson: Ucwaningo oluncane luthole ukuthi izimpawu zesifo sikaParkinson zithuthukile ngemuva kwezinsuku ezingama-28 ekudleni ketogenic ().

Ukudla kwe-ketosis kanye ne-ketogenic kungasiza ngezifo eziningi ezingamahlalakhona.

Ingabe i-ketosis inemiphumela emibi yezempilo?

Ngenkathi ukudla kwe-ketogenic kungaba nezinzuzo zempilo nokulahleka kwesisindo, nakho kungadala eminye imiphumela emibi.

Imiphumela yesikhathi esifushane ifaka ikhanda, ukukhathala, ukuqunjelwa, amazinga aphezulu e-cholesterol, nokuphefumula okungalungile (,), kepha lokhu kuvame ukunyamalala ezinsukwini ezimbalwa noma emasontweni ukuqala kokudla.

Futhi, kungaba khona ingozi yokuthuthukisa amatshe ezinso (,,).

Ngenkathi uncelisa ibele, abanye besifazane bahlakulele i-ketoacidosis, mhlawumbe ngenxa ye-carb ephansi noma i-ketogenic diet (,,).

Abantu abathatha imishanguzo yokwehlisa ushukela egazini kufanele babonane nodokotela ngaphambi kokuzama ukudla okune-ketogenic, ngoba ukudla kunganciphisa isidingo semithi.

Ngezinye izikhathi izidlo ze-ketogenic ziphansi kwe-fiber. Ngalesi sizathu, kuwumqondo omuhle ukuqinisekisa ukuthi udla ifayibha eningi ephezulu, imifino ephansi ye-carb.

Amathiphu alandelayo angakusiza ukuthi uhlale uphilile ngesikhathi se-ketosis ():

• Phuza uketshezi oluningi, ikakhulukazi amanzi.
• Khuluma nodokotela wakho ngaphambi kokuqala ukudla bese ulandela izeluleko zabo.
• Gada umsebenzi wakho wezinso ngenkathi ulandela ukudla.
• Funa usizo uma unezinkinga ngemiphumela emibi.

I-Ketosis ingaba wusizo kwabanye abantu, kepha kufanele ubuze udokotela wakho ngaphambi kokushintshela ekudleni okuphansi kakhulu kwe-carb, uma kungenakukufanele.

I-Ketosis iphephile kubantu abaningi. Kodwa-ke, abanye abantu bangaba nemiphumela engemihle, kufaka phakathi ukunuka komlomo, ukuphathwa ikhanda nokuqunjelwa.

Okubalulekile

I-Ketosis yisimo semvelo semethabolic esingatholakala ngokulandela ukudla kwe-ketogenic.

Kungaba nezinzuzo ezahlukahlukene zezempilo, kufaka phakathi:

• ukuncipha komzimba
• amazinga kashukela egazi aphansi
• ukuncipha kokuwa kwezingane ezinesithuthwane

Kodwa-ke, ukulandela ukudla okuqinile ukwenza i-ketosis kungaba nzima kakhulu, futhi kungahle kube nemiphumela engemihle. Ngaphezu kwalokho, akubona bonke abacwaningi abavumayo ukuthi ukudla okune-keto kuyindlela engcono kakhulu yokwehlisa isisindo.

I-Ketosis akuyona eyabo bonke abantu, kepha ingazuzisa abanye abantu.
