Fasting Evidence

Protokoll

Ikel f'ħin ristrett u 16:8

Il-protokoll ta' digiħ l-aktar popolari għandu l-inqas evidenza kontrollata impressjonanti. Dan huwa x'għandu jkun magħruf qabel ma tarranġah ħajtek madwaru.

It-taħriġ li ħa l-16:8

It-test l-aktar nadif tal-ikel ristrett fil-ħin ta' ltaqgħa lil iż-żewġ gruppi l-istess intake tal-kaloriji preskritt u varja biss jekk l-ikel kienx imqassam f'perjodu [9]. Matul tnax-il xahar, it-tnaqqis fil-piż kien simili f'żewġ naħat. Minħabba li l-kaloriji kienu qabbad, id-disinn jisolvi l-perjodu nnifsu — u l-perjodu kkontribwixxa ftit.

Dan huwa importanti għax ħafna ta' l-evidenza pożittiva tal-ikel ristrett fil-ħin ma jikkontrollawx l-intake. Meta tgħid lil nies jieklu biss bejn id-12 u l-8pm, jieklu inqas. It-tnaqqis fil-piż huwa reali; l-attribuzzjoni tiegħu għall-bijoloġija ċirkadiana minflok għall-intake iżgħar hija l-iżball.

L-ebda benefiċċju addizzjonali fil-kaloriji qabbad

Fejn jagħmel post tiegħu

Żewġ taħriġ imħallat f'popolazzjonijiet klinċi huma aktar inkoraġġanti. F'adulti b'sindromu metaboliku, l-ikel ristrett fil-ħin ittejjeb l-aħjar riżultati kontra l-kura standard [7]. F'adulti b'diabetes tat-tip 2, huwa pproduċa tnaqqis fil-piż f'komparazzjoni imħallata [8]. U taħriġ li jikkombina approċċ b'karboidrati baxxi ma' ikel ristrett fil-ħin rapporta bidliet fil-piż u fil-mikrobioma tal-imsaren [6].

Reviżjoni sistematika tal-ikel ristrett fil-ħin kombinat ma' eżerċizzju sabet aħjar kompożizzjoni tal-ġisem u riżultati metabolici minn kull wieħed waħdu [2] — konsistenti mal-prinċipju ġenerali li dak li tagħmel ġewwa l-perjodu huwa aktar importanti mill-perjodu.

Nota prattika

  • Perjodi aktar kmieni jistgħu jiksbu aktar minn dawk aktar tard. Ara meal timing — din hija l-parti tal-istorja ċirkadiana li tikkonforma.
  • Il-proteina hija l-kundizzjoni. Żewġ ikliet jagħmlu li tilħaq mira ta' proteina iktar diffiċli minn tlieta. Ippjana dan minflok tistenna.
  • Kafè iswed, tè u ilma ma jħallux xejn relevanti. Id-definizzjoni metabolika ta' "kiser digiħ" li għandha importanza għall-tnaqqis fil-piż hija kaloriji.
  • Tista' ma tespandi l-perjodu biex tikkumpensa għal ġurnata ħażina. Perjodi itwal ma ġewx muri li jżidu benefiċċju, u l-aderenza hija l-assett hawn.

Mistoqsijiet komuni

Huwa 16:8 aħjar minn 14:10?
Prova randomised qabblet 16:8 ma' 14:10 u kontroll fuq riżultati tal-piż u metaboliċi, u d-differenzi bejn iż-żewġ twieqi ma kinux drammatiċi. Id-defiċit jimporta aktar mis-sigħat eżatti.
It-tul tat-tieqa tal-ikel jimporta xejn?
Biss sa fejn tibdel kemm tiekol. B'kaloriji mqabbla, il-prova tan-NEJM ma sabet essenzjalment l-ebda effett indipendenti [9].
Għandi naqbeż il-kolazzjon jew l-ikla ta' filgħaxija?
L-evidenza ċirkadjana tiffavorixxi ftit li tiekol aktar kmieni, li jfisser li taqbeż l-ikla ta' filgħaxija minflok il-kolazzjon. L-aderenza ġeneralment tindika l-oppost. Ara il-ħin tal-ikliet.
Huwa sigur fit-tul?
Għall-biċċa l-kbira tal-adulti f'saħħithom, iva. Hemm eċċezzjonijiet sinifikanti — ara is-sikurezza.
