Fasting Evidence

Meitibileach

Fasting agus do shúile fola, inslin agus lipéid

Feabhsíonn marcóirí. Is é an cheist dhúshlánach an bhfeabhsaíonn siad níos mó ná mar a dhéanfadh siad ó chaillteanas meáchain céanna a bhaint amach ar bhealach eile.

Cad a deir na hathbhreithnithe is ardchaighdeáin

Is iad an t-athbhreithniú Cochrane ar ocsaint do dhaoine fásta le h-ollmhór nó obair [1] agus an t-athbhreithniú córais BMJ ar straitéisí ocsaint [2] na dhá chomhoibriú le léamh má léann tú ach dhá. Faigheann an dá cheann éifeachtaí fíor ar mheáchan agus marcóirí cardiometabolach gaolmhara, agus tá an dá cheann cúramach faoi mhéid agus cinnteacht na n-éifeachtaí sin.

An caveat athfhillte: feabhsíonn marcóirí go comhoiriúnach le meáchan a chailltear. Fuair trials a chuir ocsaint eatramhach i gcomparáid le teorannú fuinnimh leanúnach i gcoinníoll diaibéiteas 2 torthaí comhoiriúnacha [4], atá mar a bheadh tú ag súil leis má tá an meicníocht an laige.

Feabhsú gliceamach

Na trials diaibéiteas

Is é an trial EARLY an ceann is suimiúla ó thaobh cliniciúil de: aiste bia 5:2 ocsaint eatramhach a tástáil le haghaidh rialú gliceamach i ndaoine fásta le diaibéiteas, le HbA1c mar an pointe deiridh [6]. Tógann an h-ithmheán go leor den fhadhb comhoiriúnachta, rud a d'fhéadfadh a bheith mar gheall ar an toradh dearfach.

Tuairiscíodh comparáid randamach idir 16:8 agus 14:10 agus grúpa rialaithe ar an dá mheáchain laghdú agus paraiméadair meitibileach [8], ag neartú go bhfuil fad na fuinneoige ní hé an comhábhar gníomhach.

Tábhacht aoise

Is fiú léamh athbhreithniú a scrúdaíonn go sonrach rioscaí agus sochair ocsaint do chóras cardio-vascúla ag dul in aois [3] má tá tú os cionn 60. Tá níos lú mais lean i ndaoine fásta níos sine le cailliúint, níos mó idirghníomhaíochtaí le leigheasanna, agus seans níos airde go gcuirfidh tréimhse laghdaithe intake fadhbanna a d'fhéadfadh a bheith trivial ag 30. Is é trial Cell Metabolism a thomhas freagairtí inchinn do ocsaint eatramhach i gcomparáid le aiste bia sláintiúil i ndaoine fásta [7] ar cheann de na few staidéir atá deartha don daonra seo.

Cad nach bhfuil ag seasamh

  • "Tugann ocsaint ar ais íogaireacht inslin go neamhspleách ar chailliúint meáchain." Níor bunaíodh. Ní léiríonn trials a comhoiriúnódh athrú meáchain éifeacht shoiléir neamhspleách.
  • "Tugann ocsaint ar do cholesterol." Gluaiseann lipéid le meáchan agus comhoibriú aiste bia. Níl éifeacht lipéid shonrach bunaithe ag ocsaint ar a shon féin.
  • "Tugann ocsaint ar laghdú ar athlasadh." Titeann marcóirí athlasachta le cailliúint saill. Éilíonn a chur in iúl sin don patrún ocsaint rialú a bhfuil laige ag go leor trials.
  • "Beidh tú oiriúnaithe saill agus dófaidh tú saill ar feadh an lae." Athraíonn úsáid substráit le linn ocsaint agus athraíonn sé ar ais tar éis ithe. Tá ocsaint saill tríocha a hocht uair an chloig faoi smacht ar chothromaíocht fuinnimh.

Ceisteanna coitianta

An mbeidh ocsaint ag casadh mo phre-diaibéiteas?
Laghdaíonn cailliúint meáchain go mór an dul chun cinn chuig diaibéiteas 2, agus is bealach é ocsaint chun cailliúint meáchain a bhaint amach. Níl aon fhianaise ann go bhfuil sé níos fearr ná bealaí eile chun an chailliúint chéanna a bhaint amach.
An bhfuil mo léamha glúcóis ocsaint ag ardú ag ciall nach bhfuil sé ag obair?
Féadfaidh glúcós ocsaint ardú go sealadach le linn ocsaint fada mar a choinníonn an ae soláthar. Ní comhartha dochar é sin ina aonar, ach pléigh aon léamha neamhghnácha le cliniceoir.
An bhfuil ocsaint maith do cholesterol?
Go doléite, trí chailliúint meáchain agus go minic trí fheabhsú ar cháilíocht aiste bia. Níl aon éifeacht lipéid shonrach ocsaint bunaithe.
An féidir liom ocsaint le diaibéiteas 2?
Tá trials déanta go sábháilte faoi mhaoirseacht, lena n-áirítear i n-othair a bhfuil inslin á thógáil acu. Is é an chuid dainséarach ná é a dhéanamh gan coigeartú leigheas — féach sábháilteacht.
