Framman tíðarfest matgerð: hvat vísindini vísa
Vindeyga flytt fram, t.d. 8am-4pm
Hvat vísindin stuðla
Smáar stýrðar matarroyndir vísa, at at eta fyrr um dagin betrar insulinsensitivitet og glykemiska stýring óheft av vekt, í samsvari við circadian biologii. [1]
Royndirnar eru smáar, og tíðarskipanirnar eru sosialt torførar at halda. Metabolisku signalini eru meira áhugaverd enn vektarsignalini.
Tað, fólk missa av sæð
Ígjøgnum tilfelli, fasting protokollir framleiða vektartap samanborið við samfelags orku takni av sama stødd. Har ein roynd javnsetur kaloríur, vinnur fasting armurin sjaldan. Hetta er støðugt frágreitt og støðugt undirkommunikerað, tí at "tá virkar tað umleið eins væl sum at eta minni" er ein ringur fyrisøgn.
Tað er framvegis ein gagnlig úrslit. Fyrst og fremst er ein regla um, nær at eta, nógv lættari at fylgja enn ein regla um, hvussu nógv, og at halda seg er tað, sum veruliga avger úrslitini yvir eitt ár.
Aðrar protokollir
- 16:8 tíðarfest matgerð — et innan 8 tímar, fasta 16
- 5:2 matarætlanin — tveir sterkt avmarkaðir dagar um vikuna
- Skiftidags fasting — skiftandi etin og fasta ella sera-lítla kaloríudagar
- Ein máltíð um dagin (OMAD) — ein einastandandi dagligur máltíðartíð
- Long fasting (48 tímar og meira) — fleiri dagar, vatn ella lítla inntøku
Virkar framman tíðarfest matgerð?
Er tað betri enn bara at eta minni?
Fari eg at missa vøtt?
Hvat skal forðast?
