Protokol
Zgodnje časovno omejeno prehranjevanje: dokazi
Okno premaknjeno zgodaj, npr. 8:00-16:00
Kaj podpirajo dokazi
Majhne študije s kontroliranim prehranjevanjem nakazujejo, da zgodnejše prehranjevanje izboljša občutljivost na inzulin in glikemično kontrolo neodvisno od teže, kar je skladno s cirkadiano biologijo. [1]
Poskusi so majhni in razporedi so socialno težko vzdrževati. Metabolni signal je bolj zanimiv kot signal teže.
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
- Dieta 5:2 — dva močno omejena dneva na teden
- Post na izmenične dni — izmenično dni hranjenja in posta ali zelo nizkokalorične dni
- En obrok na dan (OMAD) — en sam dnevni obrok
- Podaljšano postenje (48 ur in več) — večdnevno, voda ali minimalni vnos
Ali deluje zgodnje časovno omejeno prehranjevanje?
Je to boljše kot preprosto jesti manj?
Ali bom izgubil mišično maso?
Kdo bi se temu moral izogibati?
