Fasting Evidence

Phrótacal

Itheamh teoranta ama agus 16:8

Tá an prótacal ocrais is coitianta ag fáil na cruthúnas rialaithe is lú suimiúla. Tá sé sin tábhachtach a bheith ar an eolas sula gcuireann tú do shaol in ord timpeall air.

An turgnamh a laghdaigh 16:8

Thug an tástáil is glan de ithe ama teoranta an t-ídiú calraí comhoibrithe do gach grúpa agus níor athraigh ach an raibh ithe teoranta do fuinneog [9]. I rith dho mhí, bhí caillteanas meáchain comhionann i mbeirt na gcruinní. Toisc go raibh calraí comhoibrithe, scarann an dearadh an fuinneog féin — agus níor chuir an fuinneog go leor le haon rud.

Tá sé seo tábhachtach mar níl an chuid is mó de na turgnaimh ithe ama teoranta ag rialú an t-ídiú. Nuair a deir tú le daoine ithe ach idir a hocht a chlog agus a hocht a chlog, itheann siad níos lú. Tá an caillteanas meáchain fíor; is é an botún é a chur i leith bitheolaíocht circadian seachas an t-ídiú níos lú.

Níl aon bhuntáiste breise ag calraí comhoibrithe

Áit a bhfuil a phost aige

Tá dhá thurgnamh randamacha i gcoinníoll cliniciúla níos spreagúla. I measc daoine fásta le meitibileacht, tháinig feabhas ar thorthaí in aghaidh cúraim chaighdeánach [7]. I measc daoine fásta le diaibéiteas cineál 2, tháinig caillteanas meáchain i gcomparáid randamach [8]. Agus tuairiscigh turgnamh a chomhcheanglaíonn cur chuige íseal-carb le ithe ama teoranta athruithe ar mheáchan agus ar mhicreafhóin gut [6].

Fuair ​​athbhreithniú sistemach ar ithe ama teoranta comhoibrithe le gníomhaíocht fhisiciúil torthaí comhoiriúnachta agus meitibileachta níos fearr ná aon cheann amháin [2] — comhoiriúnach leis an gprionsabal ginearálta go bhfuil an méid a dhéanann tú laistigh den fuinneog níos tábhachtaí ná an fuinneog.

Conas a rangóidh na prótacail i gcomparáid lena chéile

Tabhair faoi deara go gcuireann an t-ordú in iúl cé chomh mór atá an laige a chruthaíonn gach prótacal. Sin é an scéal iomlán i dtábla amháin. Níos mó ar 5:2 agus lá malartach.

Nótaí praiticiúla

  • D'fhéadfadh fuinneoga níos luaithe a bheith níos fearr ná na cinn níos déanaí. Féach timing béilí — is é seo an chuid de scéal circadian a choinníonn suas.
  • Is é próitéin an srianta. Déanann dhá bhéile an sprioc próitéine a bhaint níos deacra ná trí. Plean é seachas ag súil.
  • Ní bhrisfidh caife dubh, tae agus uisce aon rud ábhartha. Is é an sainmhíniú meitibileachta ar "briseadh ocrais" atá tábhachtach do chaillteanas meáchain ná calraí.
  • Ná síneadh an fuinneog chun comhoiriúnacht a chur in ionad lá dona. Níor léirigh fuinneoga níos faide go n-ardóidh siad sochar, agus is é an comhoiriúnacht an sócmhainn anseo.

Ceisteanna coitianta

An bhfuil 16:8 níos fearr ná 14:10?
Chuir triail randamaithe 16:8 i gcomparáid le 14:10 agus grúpa rialaithe ó thaobh meáchain agus torthaí meitibileacha de, agus níorbh drámatúla na difríochtaí idir an dá fhuinneog. Tá an t-easnamh calraí níos tábhachtaí ná na huaireanta beachta.
An bhfuil tábhacht ar bith le fad na fuinneoige itheacháin?
Ach amháin a mhéid a athraíonn sé cé mhéad a itheann tú. Ag calraí comhoiriúnaithe, fuair triail NEJM go bunúsach gan éifeacht neamhspleách [9].
Ar cheart dom bricfeasta nó dinnéar a scipeáil?
Tacaíonn an fhianaise ciorcaid go héadrom le hithe níos luaithe, rud a chiallaíonn dinnéar a scipeáil seachas bricfeasta. Is gnách go dtéann cloí leis an treo eile. Féach uainiú béilí.
An bhfuil sé sábháilte ar feadh an tréimhse fhada?
D'fhormhór na ndaoine fásta sláintiúla, tá. Tá eisceachtaí suntasacha ann — féach sábháilteacht.
