Protokol
Ishrana sa vremenskim ograničenjem i 16:8
Najpopularniji protokol posta ima najmanje impresivne kontrolisane dokaze. To je važno znati pre nego što reorganizujete svoj život oko njega.
Ispitivanje koje je oborilo 16:8
Najčišće testiranje jela sa vremenskim ograničenjem dalo je obe grupe sa istim propisanim unosom kalorija i variralo samo da li je jelo ograničeno na prozor [9]. Tokom dvanaest meseci, gubitak težine bio je sličan u obe grupe. Pošto su kalorije bile usklađene, dizajn izoluje prozor samog — a prozor je doprineo malo.
To je važno jer većina pozitivnih ispitivanja jela sa vremenskim ograničenjem ne kontroliše unos. Kada kažete ljudima da jedu samo između podneva i 20h, jedu manje. Gubitak težine je stvaran; pripisivanje toga cirkadianoj biologiji umesto manjem unosu je greška.
Nema dodatne koristi pri usklađenim kalorijama
Gde zaslužuje svoje mesto
Dva randomizovana ispitivanja u kliničkim populacijama su ohrabrujuća. Kod odraslih sa metaboličkim sindromom, jelo sa vremenskim ograničenjem poboljšalo je ishode u odnosu na standardnu negu [7]. Kod odraslih sa dijabetesom tipa 2, došlo je do gubitka težine u randomizovanoj komparaciji [8]. A ispitivanje koje je kombinovalo pristup sa niskim udelom ugljenih hidrata sa jelom sa vremenskim ograničenjem izvestilo je o promenama u težini i crevnoj mikrobioti [6].
Sistematski pregled jela sa vremenskim ograničenjem kombinovanog sa vežbanjem pokazao je bolje rezultate u telesnoj kompoziciji i metabolizmu nego bilo koji od njih pojedinačno [2] — u skladu sa opštim principom da ono što radite unutar prozora ima veći značaj od samog prozora.
Kako se protokoli rangiraju jedni protiv drugih
| Protokol | Tipično pravilo | Relativni efekat na težinu | Održivost |
|---|---|---|---|
| 16:8 / vremenski ograničeno | Jedite unutar dnevnog prozora od 8 sati | Najmanji od tri | Najviši — većina ljudi može ovo da izdrži |
| 5:2 | Dva strogo ograničena dana nedeljno | Umereno | Umereno |
| Alternativni dan | Ograničeno svaki drugi dan | Najveći | Najniži — visoka stopa odustajanja u ispitivanjima |
Napomena da redosled prati koliko veliki deficit svaki protokol stvara. To je cela priča u jednoj tabeli. Više o 5:2 i alternativnom danu.
Praktične napomene
- Raniji prozori mogu biti bolji od kasnijih. Pogledajte vreme obroka — ovo je deo cirkadiane priče koji se drži.
- Proteini su ograničenje. Dva obroka otežavaju postizanje cilja proteina nego tri. Planirajte to umesto da se nadate.
- Crna kafa, čaj i voda ne prekidaju ništa relevantno. Metabolička definicija "prekidanja posta" koja je važna za gubitak težine su kalorije.
- Ne produžavajte prozor da biste nadoknadili loš dan. Duži prozori nisu pokazali dodatne koristi, a pridržavanje je ovde prednost.
Često postavljana pitanja
Da li je 16:8 bolje od 14:10?
Да ли је дужина временског прозора за јело уопште важна?
Да ли треба да прескочим доручак или вечеру?
Da li je dugoročno bezbedno?
