Weight Loss Evidence

Aistí bia

Cén aiste bia is fearr le haghaidh caillteanas meáchain?

Leanann an méta-anailís ag táirgeadh an t-aistriúchán céanna, agus is é an freagra nach bhfuil ag éileamh ag aon duine: ag dhoimhneacht dhoimhne, tá na difríochtaí idir na haistí bia ainmnithe beag.

Cad a thaispeánann na méta-anailísí comparáideacha

Is é an anailís is úsáideach a rinne comparáid idir patrúin macronutrient aistí bia trasna 14 aistí bia ainmnithe coitianta [4]. Ag sé mhí, léirigh cur chuige íseal-charbón buntáiste beag. Ag dhoimhneacht dhoimhne, tá na difríochtaí idir na haistí bia tar éis dul i ngleic go dtí an pointe nach bhfuil sé cliniciúil, agus tá gach duine acu tar éis talamh a chailleadh i gcomparáid lena dtorthaí sé mhí.

Bhí méta-anailís de íseal-saill i gcomparáid le híoslaghadh charbón ag teacht le conclúidí comhoiriúnacha [5], mar a rinne comparáid níos leithne ar éifeachtaí caillteanas meáchain i measc daoine fásta le róthrom nó obezity [1].

Convergeann aistí bia ag 12 mhí

Cén fáth a gconvergeann siad

Oibríonn gach aiste bia seo trí dhó a tháirgeadh, agus déanann gach duine é trí rud a shrianadh. Baintear catagóir bia le híoslaghadh charbón; baintear catagóir eile le híoslaghadh saill; athraíonn patrún Mheánmhuir comhoiriúnacht agus cuireann sé bia próiseáilte as. Tá an meicníocht difriúil; níl an comhoiriúnacht difriúil.

Tugann an comhoiriúnacht thar am le fios go bhfuil laghdú ar choinníoll, atá an-similar trasna na haistí bia. Ní stopann daoine toisc nach bhfuil a n-aiste bia ag obair. Stopann siad toisc go bhfuil sé deacair aon shrian a chothú.

Tugann patrún Mheánmhuir nóta: níl sé neamhghnách le haghaidh caillteanas meáchain agus tá na fianaise is fearr aige de aon phatrún aiste bia le haghaidh torthaí croí. Is ceisteanna difriúla iad sin, agus tá sé coitianta iad a chur le chéile.

Aistí bia ketogenic go sonrach

Fuair méta-anailís buntáistí le haghaidh caillteanas meáchain, rialú gliceamach agus próifíl lipid [3]. Tá dhá caveat tábhachtach. Tá an caillteanas luath infláite ag glycogen agus an t-uisce a bhaineann leis — roinnt cilig a fhilleann ar athbhreithniú gan aon saill a bheith faighte. Agus tá comhoiriúnacht ag dhoimhneacht dhoimhne go dona i go leor trialacha, agus is é sin an fáth go gconvergeann na torthaí fadtéarmacha.

Tá comhoiriúnachtaí á tástáil freisin: rinne trialacha randamacha a shocrú aiste bia íseal-charbón sláintiúil le hithir teoranta ama [6], atá clúdaithe tuilleadh ar ár suíomh fianaise ocrais.

Ag roghnú, go praiticiúil

  1. Roghnaigh an ceann is féidir leat a shamhlú a dhéanamh i mbliain. Ní pléascadh é seo — is é an méid a deir na sonraí dhoimhneacht dhoimhne.
  2. Is fearr patrúin ná prótacail. Rud a féidir leat a ithe le do theaghlach a bhuaigh rud a éilíonn béilí ar leith.
  3. Cosain próitéin agus snáithín beag beann ar an patrún. Cuidíonn an dá rud le sásamh agus mais chothrom. Féach próitéin.
  4. Bí ag breithniú ag trí mhí, ní trí seachtain. Tá na difríochtaí luath idir na haistí bia go mór uisce.
  5. Má tá diaibéiteas cineál 2 agat, athraíonn an comhoiriúnacht. Rinneadh athbhreithniú ar chomhoiriúnacht aistí bia sa phobal sin go sonrach [2].

Ceisteanna coitianta

An é calra calra?
Le haghaidh cothromaíocht fuinnimh, sách gar. Le haghaidh sáithiú, costas bia agus cloí, ní hea ar chor ar bith — sin an fáth a bhfuil comhdhéanamh an aiste bia fós tábhachtach cé go dtiteann na hiomláin dhá mhí dhéag le chéile.
Cén fáth ar chaill mé 3 kg sa chéad seachtain ar an aiste keto?
Ídiú glycogein agus an t-uisce atá ceangailte leis. Filleann sé nuair a fhilleann carbaihiodráit, agus níorbh saill riamh é.
An í an aiste bia Mheánmhuirí an ceann is fearr?
Maidir le torthaí cardashoithíocha, tá an fhianaise is láidre aici d'aon phatrún. Maidir le caillteanas meáchain go sonrach, feidhmíonn sí cosúil leis na cinn eile.
Ar chóir dom calraí a chomhaireamh?
Tuarann féin-mhonatóireacht rath — féach athrú iompraíochta — ach is féidir leis an monatóireacht a bheith ar iontógáil, ar mheáchan, nó ar chloí le riail. Rogha amháin is ea comhaireamh, ní an t-aon rogha.
