Protokoll
Längeren Fasting (48 Stonnen a méi): wat d'Evidenz weist
Multi-Tag, Waasser oder minimal Intake
Wat d'Evidenz ënnerstëtzt
Haaptsächlech fir metabolesch an Autophagie Marker studéiert, net fir Gewiicht. Effekter op Ketonkierper an Insulin sinn echt an mesurable. [1]
Refeeding-Syndrom ass e wierkleche klinesche Risiko no verlängertem Fasting an kann fatal sinn. Elektrolytstéierungen sinn d'spezifesch Gefor. Dëst ass keen Ufängerprotokoll an ass net passend ouni Supervision.
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
- D'5:2 Diät — zwou staark limitéiert Deeg pro Woch
- Alternéierend Deeg Fasting — alternéierend gefiddert an gefaste oder ganz-niddereg-Kalorie Deeg
- Eng Mëssioun pro Dag (OMAD) — eng eenzeg täglech Iessgeleeënheet
Funktionéiert verlängert Fasting (48 Stonnen an méi)?
Ass et besser wéi just manner ze iessen?
Verluer ech Mëscle?
Wien sollt et vermeiden?
