16:8 dieta ristretta fiż-żmien: x'juri l-evidenza
Ikel fi ħdan 8 sigħat, fast 16
X'jappoġġja l-evidenza
Il-window l-aktar studjat. It-testi randomizzati ġeneralment isibu t-telf ta' piż komparabbli ma' restrizzjoni ta' kalori magħquda — il-mekkaniżmu huwa prinċipalment li window iqsar inaqqas l-intake, mhux li l-arloġġ innifsu jagħmel xi ħaġa addizzjonali. [1]
TREAT u testi simili ma sabu l-ebda vantaġġ fuq restrizzjoni sempliċi ta' kalori, u wieħed rapporta telf akbar ta' massa magra. L-appell huwa l-aderenza, mhux is-superjorità.
Il-konklużjoni li n-nies jaħsbu li jmiss
Madwar il-letteratura randomizzata, il-protokolli tal-fasting jipproduċu t-telf ta' piż komparabbli ma' restrizzjoni kontinwa ta' enerġija tal-istess magnitudni. Fejn test jikkonverġi l-kalori, il-parti tal-fasting rarament tirbaħ. Dan huwa rapportat b'mod konsistenti u taħt-komunikat b'mod konsistenti, għax "jaħdem kważi daqslikieku tiekol inqas" huwa titolu fqir.
Hija għadha riżultat utli. Għal xi nies, regola dwar meta tiekol hija ħafna aktar faċli biex tiġi segwita milli regola dwar kemm, u l-aderenza hija l-affarijiet li tassew jiddeterminaw ir-riżultati matul sena.

Ikkonferma 16:8 dieta ristretta fiż-żmien taħdem?
Il-window l-aktar studjat. It-testi randomizzati ġeneralment isibu t-telf ta' piż komparabbli ma' restrizzjoni ta' kalori magħquda — il-mekkaniżmu huwa prinċipalment li window iqsar inaqqas l-intake, mhux li l-arloġġ innifsu jagħmel xi ħaġa addizzjonali.
Huwa aħjar milli sempliċement tiekol inqas?
Skont l-evidenza, le — ir-riżultati jikkonverġu meta l-kalori jkunu ekwivalenti. Huwa aħjar jekk ikun aktar faċli għalik li żżommha, li huwa vantaġġ reali aktar milli konsolazzjoni.
Se nitilfu l-muskoli?
Kull defiċit ta' enerġija jiswa xi massa magra. Proteina adegwata u taħriġ ta' reżistenza huma l-mitigazzjonijiet b'evidenza warajhom, u l-ebda wieħed mhu speċifiku għall-fasting.
Min għandu jevitah?
Tqala u ikel tal-ħalib, storja ta' ikel disordnat, tip 1 diabetes, u xi ħadd fuq mediċina li teħtieġ ikel jew li taffettwa l-glukoż. Fasting prolungat iżid ir-riskju ta' refeeding fuq kollox.
