Tímatakmarkað mataræði og 16:8
Vinsælasta fasta prótokollin hefur minnst áhrifamikla stjórnaða sönnun. Það er vert að vita áður en þú raðar lífi þínu í kringum það.
Rannsóknin sem dró úr 16:8
Hreinasta prófunin á tímatakmarkaðri mataræði gaf báðum hópunum sömu fyrirskipuðu kaloríuinntöku og breytti aðeins því hvort mataræði var takmarkað við viku [9]. Í tólf mánuði var þyngdartap svipað í báðum arms. Vegna þess að kaloríur voru samræmdar, einangrar hönnunin vikuna sjálfa — og vikan skilaði litlu.
Þetta skiptir máli vegna þess að flestar jákvæðar rannsóknir á tímatakmarkaðri mataræði stjórna ekki inntöku. Þegar þú segir fólki að borða aðeins milli klukkan 12 og 20, borða þeir minna. Þyngdartapið er raunverulegt; að tengja það við sólarhringslíffræði frekar en við minni inntöku er villan.
Engin viðbótar ávinningur við samræmdar kaloríur
Þar sem það fær sinn stað
Tvær slembirannsóknir í klínískum hópum eru hvetjandi. Í fullorðnum með efnaskiptasjúkdóm, bætti tímatakmarkað mataræði útkoma gegn staðlaðri umönnun [7]. Í fullorðnum með 2. tegund sykursýki, leiddi það til þyngdartaps í slembisamanburði [8]. Og rannsókn sem sameinaði lágt kolvetna nálgun með tímatakmarkaðri mataræði skýrði breytingar á þyngd og þarmamyndun [6].
Kerfisbundin yfirlit yfir tímatakmarkað mataræði sameinað með æfingum fann betri líkamsgerð og efnaskiptauðkenni en hvort tveggja fyrir sig [2] — í samræmi við almenna meginreglu að það sem þú gerir innan vikunnar skiptir meira máli en vikan.
Hvernig prótokollin raðast saman
| Aðferð | Venjuleg regla | Afleiðing á þyngd | Sjálfbærni |
|---|---|---|---|
| 16:8 / tímatakmarkað | Borða innan 8 klukkustunda glugga daglega | Minst af þremur | Hæst — flestir geta haldið þessu áfram |
| 5:2 | Tvö mjög takmörkuð dagar á viku | Í meðallagi | Í meðallagi |
| Fasta daga | Takmarkað á hverjum öðrum degi | Stærst | Lægst — mikil brottfall í rannsóknum |
Athugið að röðin fylgir því hversu stóran skort hver prótokoll skapar. Það er allt sagan í einni töflu. Frekari upplýsingar um 5:2 og fasta daga.
Praktískir punktar
- Fyrri gluggar gætu verið betri en seinni. Sjá matar tímasetningu — þetta er hluti af sólarhringssögunni sem heldur.
- Prótein er takmörkunin. Tvö máltíðir gera það erfiðara að ná próteintakmarki en þrjú. Skipuleggðu það frekar en að vona.
- Svart kaffi, te og vatn brjóta ekki neitt mikilvægt. Efnaskiptaskilgreiningin á "að brjóta fasta" sem skiptir máli fyrir þyngdartap eru kaloríur.
- Ekki framlengja gluggann til að bæta upp fyrir slæman dag. Lengri gluggar hafa ekki sýnt að bæta ávinning, og aðhald er eignin hér.
