Cad a thacaíonn an cruthúnas

Comparáidí randamacha a fhaigheann caillteanas meáchain go ginearálta comhoiriúnach le srianta calraí leanúnacha thar 6-12 mí. [1]

Comhoiriúnach, ní níos fearr. Is ceist faoi dhuine, ní faoin bprótacal, atá ann maidir le cén ceann a oibríonn.

Láidreacht na fianaise trasna na bprótacal ocrais atá próifílithe As na 6 bprótacal ocrais atá próifílithe, léiríonn sé cé mhéad atá ag gach leibhéal fianaise, le An aiste bia 5:2 grádaithe mar bhunaithe. Established3 protocolsLimited2 protocolsPromising1 protocols
Tá an aiste bia 5:2 grádaithe mar bhunaithe. Tabhair faoi deara nach deir na grádanna ní a bhfuil a fhios againn go n-oibríonn prótacal a bhfuil fianaise mhaith air go comhoiriúnach le srianta calraí gnáth, ní ceann a bhuaileann é. Grádanna a shocraítear ó dhearadh trial agus athdhéanamh.

An toradh a chailltear ag daoine

Trasna na litríochta randamacha, tá prótacal ocrais ag táirgeadh caillteanas meáchain atá comhoiriúnach le srianta fuinnimh leanúnacha den mhéid céanna. Nuair a comhoireann calraí, is annamh a bhuaileann an t-arm ocrais. Tuairiscítear é seo go comhoiriúnach agus tá sé faoi chumarsáid go comhoiriúnach, mar is droch-titim é "oibríonn sé go comhoiriúnach le ithe níos lú".

Tá sé fós ina thoradh úsáideach. Do roinnt daoine, tá rialacha faoi nuair a itheann tú i bhfad níos éasca le leanúint ná rialacha faoi cé mhéad, agus is é comhoiriúnacht an rud a chinneann torthaí thar bhliain.

Prótacail eile

An oibríonn an aiste bia 5:2?
Comparáidí randamacha a fhaigheann caillteanas meáchain go ginearálta comhoiriúnach le srianta calraí leanúnacha thar 6-12 mí.
An bhfuil sé níos fearr ná díreach ithe níos lú?
De réir na fianaise, ní — comhoireann na torthaí nuair a comhoireann calraí. Is fearr é más éasca duit é a choinneáil, atá ina bhuntáiste fíor seachas comhoiriúnacht.
An gcaillfidh mé matán?
Cuirtear costas ar aon easnamh fuinnimh ar roinnt mais lean. Is éard atá i gceist le próitéin chuí agus traenáil frithsheasmhachta na míochainí atá le fianaise ina dhiaidh sin, agus ní bhíonn aon cheann acu sonrach do ocrais.
Cé ba chóir é a sheachaint?
Toirchis agus lachtadh, stair itheacháin neamhordacha, diaibéiteas 1, agus aon duine ar chógas a éilíonn bia nó a théann i bhfeidhm ar ghlas. Cuireann ocrais fhada riosca athchóirithe ar bharr.
