Postenje na izmenične dni: kaj dokazi kažejo
Izmenični dnevi hranjenja in postenja ali zelo nizkokalorični dnevi
Kaj podpirajo dokazi
Proučuje izgubo teže v poskusih; največje primerjave ne najdejo prednosti pred dnevno omejitvijo in opazno višjo stopnjo opustitve. [1]
Usklajenost je ponavljajoč problem. Protokol, ki deluje v poskusu in ne v življenju, ni boljši protokol.
Ugotovitev, ki jo ljudje spregledajo
V celotni randomizirani literaturi protokoli postenja proizvajajo izgubo teže, primerljivo s stalno omejitvijo energije iste magnitude. Kjer poskus izenačuje kalorije, postna skupina redko zmaga. To je dosledno poročano in dosledno slabo komunicirano, ker "deluje približno tako dobro kot jesti manj" ni dobra naslovna novica.
Še vedno je to uporaben rezultat. Za nekatere ljudi je pravilo o tem, kdaj jesti, veliko lažje slediti kot pravilu o tem, koliko, in usklajenost 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
- En obrok na dan (OMAD) — en sam dnevni obrok
- Podaljšano postenje (48 ur in več) — večdnevno, voda ali minimalni vnos
Ali deluje postenje na izmenične dni?
Je to boljše kot preprosto jesti manj?
Ali bom izgubil mišice?
Kdo bi se temu moral izogibati?
