Protokol
Produženo postenje (48 sati i više): dokazi
Višednevno, voda ili minimalni unos
Šta dokazi podržavaju
Istraživano uglavnom za metaboličke i autophagy markere, a ne za težinu. Efekti na ketonska tijela i insulin su stvarni i mjerljivi. [1]
Sindrom ponovnog hranjenja je stvarni klinički rizik nakon produženog posta i može biti fatalan. Poremećaj elektrolita je specifična opasnost. Ovo nije protokol za početnike i nije prikladan bez nadzora.
Nalaz koji ljudi propuštaju
U okviru randomizirane literature, protokoli posta dovode do gubitka težine koji je uporediv sa kontinuiranom restrikcijom energije iste magnitude. Gdje ispitivanje izjednačava kalorije, grana posta rijetko pobjeđuje. Ovo se dosljedno izvještava i dosljedno nedovoljno komunicira, jer "djeluje otprilike jednako dobro kao jesti manje" je loša naslovna vijest.
I dalje je to koristan rezultat. Za neke ljude pravilo o tome kada jesti je daleko lakše slijediti nego pravilo o tome koliko, a pridržavanje je ono što zapravo određuje rezultate tokom godine.
Ostali protokoli
- 16:8 vremenski ograničeno jedenje — jedite unutar 8 sati, postite 16
- Rano vremenski ograničeno jedenje — prozor pomjeren rano, npr. 8-16
- Dijeta 5:2 — dva dana sa jakim ograničenjem nedeljno
- Post naizmjeničnih dana — naizmjenično dani sa hranom i dani posta ili vrlo niskokalorični dani
- Jedan obrok dnevno (OMAD) — jedan dnevni obrok
Da li produženo postenje (48 sati i više) funkcioniše?
Da li je bolje od jednostavno jedenja manje?
Da li ću izgubiti mišiće?
Ko bi trebao da to izbjegava?
