Protokol
Podaljšano postenje (48 ur in več): kaj dokazi kažejo
Večdnevno, voda ali minimalni vnos
Kaj podpirajo dokazi
Preučevano predvsem za presnovne in avtofagijske markerje, ne pa za težo. Učinki na ketonska telesa in inzulin so resnični in merljivi. [1]
Sindrom ponovnega hranjenja je resničen klinični rizik po dolgotrajnem postu in je lahko usoden. Motnje elektrolitov so specifična nevarnost. To ni protokol za začetnike in ni primeren brez nadzora.
Ugotovitev, ki jo ljudje spregledajo
V literaturi o randomiziranih poskusih protokoli posta prinašajo izgubo teže, primerljivo s kontinuirano omejitvijo energije iste magnitude. Kjer poskus izenačuje kalorije, postna skupina redko zmaga. To je dosledno poročano in dosledno slabo komunikacijo, ker "deluje približno tako dobro kot manj jesti" ni dobra novica.
To je še vedno uporaben rezultat. Za nekatere ljudi je pravilo o tem, kdaj jesti, veliko lažje slediti kot pravilu o tem, koliko, in upoštevanje je tisto, kar dejansko določa rezultate čez leto.
Drugi protokoli
- 16:8 časovno omejeno prehranjevanje — jejte v 8 urah, postite 16
- Zgodnje časovno omejeno prehranjevanje — okno premaknjeno zgodaj, npr. 8:00-16:00
- Dieta 5:2 — dva močno omejena dneva na teden
- Post na izmenične dni — izmenično dni z obroki in dnevi posta ali zelo nizkokaloričnimi dnevi
- En obrok na dan (OMAD) — en sam dnevni obrok
Ali podaljšano postenje (48 ur in več) deluje?
Je to bolje kot preprosto jesti manj?
Ali bom izgubil mišice?
Kdo naj se temu izogne?
