Fleiri dagar, vatn ella minimal inntøka
Hvat vísindin stuðla
Granskað fyrst og fremst fyri metaboliska og autophagy markørar heldur enn vekt. Ávirkanir á keton líkamsfrøttir og insulin eru veruligar og mátingar. [1]
Refeeding syndrome er ein verulig klinisk risikó eftir longtíðarfasting og kann vera deyðlig. Elektrolyttur órógv er serliga vandin. Hetta er ikki ein byrjandi protokoll og er ikki hóskandi uttan eftirlit.
Niðurstøðan, sum fólk missa
Ígjøgnum tað randomiserða litteraturið, framleiða fasting protokollir vægttap samanborið við samfelags orkuavmarking av sama støði. Har ein roynd jøvnkar kaloriur, vinnur fasting armurin sjaldan. Hetta er støðugt rapporterað og støðugt undirkommunikerað, tí at " tað virkar umleið eins væl sum at eta minni " er ein ringur fyrisøgn.
Tað er framvegis ein gagnlig niðurstøða. Fyrir nakrar fólk er ein reglugerð um, nær at eta, nógv lættari at fylgja enn ein reglugerð um, hvussu nógv, og at halda seg til tað er tað, sum veruliga avger úrslitini yvir eitt ár.
Aðrar protokollir
- 16:8 tíðarskipaður eting — et innan 8 tímar, fasta 16
- Fyrsta tíðarskipaða eting — vindeyga flutt tíðliga, t.d. 8am-4pm
- The 5:2 diet — tveir sterkt avmarkaðir dagar um vikuna
- Skiftidags fasting — skiftandi etin og fasta ella sera-lítla kaloríudagar
- Ein máltíð um dagin (OMAD) — ein einasta dagliga etingartíð
Virkar longtíðarfasting (48 tímar og meira)?
Er tað betri enn bara at eta minni?
Vil eg tapa vøtt?
Hvat fólk skulu forðast tað?
