Déi 5:2 Diät: wat d'Evidenz weist
Zwee staark restriktiert Deeg pro Woch
Wat d'Evidenz ënnerstëtzt
Randomiséiert Vergläicher fannen Gewiichtsverloscht, dat am Allgemengen äquivalent ass zu kontinuéierlecher Kalorie-Restriktioun iwwer 6-12 Méint. [1]
Äquivalent, net besser. Wéi eng funktionéiert ass eng Fro iwwer d'Persoun, net d'Protokoll.
D'Fannt déi Leit verfehlen
Iwwer d'randomiséiert Literatur produzéieren d'Fasting-Protokoller Gewiichtsverloscht, dat mat kontinuéierlecher Energie Restriktioun vun der selwechter Magnitude vergläichbar ass. Wou e Test Kalorien gläichstellt, gewënnt d'Fasting-Arm selten. Dëst gëtt konstant bericht an konstant ënnerkommunizéiert, well "et funktionnéiert bal esou gutt wéi manner ze iessen" ass eng schlecht Schlagzeil.
Et ass nach ëmmer e brauchbare Resultat. Fir e puer Leit ass eng Regel iwwer wann ze iessen vill méi einfach ze verfollegen wéi eng Regel iwwer wéi vill, an d'Adhäriicht ass dat, wat tatsächlech d'Resultater iwwer e Joer bestëmmt.
Anner Protokoller
- 16:8 Zäit-restriktiert Iessen — iessen an 8 Stonnen, faste 16
- Fréi Zäit-restriktiert Iessen — Fënster fréi verschoben, z.B. 8 Auer-16 Auer
- Alternéierend Deeg Fasting — alternéierend gefiddert an gefaste oder ganz-niddereg-Kalorie Deeg
- Eng Mëssioun pro Dag (OMAD) — eng eenzeg täglech Iessgeleeënheet
- Verlängert Fasting (48 Stonnen an méi) — multi-Deeg, Waasser oder minimal Intake
Funktionéiert d'5:2 Diät?
Ass et besser wéi just manner ze iessen?
Verluer ech Mëscle?
Wien sollt et vermeiden?
