Fasting Evidence

Metaboliċi

Il-fasting u s-suq tal-żejt, insulina u lipidi

Il-markers jtejjeb. Il-mistoqsija iebsa hi jekk jtejjebux iktar milli kieku kisbu l-istess telf ta' piż b'xi mod ieħor.

X'jgħidu r-reviżjonijiet ta' l-ogħla kwalità

Ir-reviżjoni Cochrane fuq il-fasting intermittenti għall-adulti b'piż żejjed jew obezità [1] u r-reviżjoni sistematika tal-BMJ tal-istrateġiji tal-fasting [2] huma t-tnejn sintesi li għandek taqra jekk taqra biss tnejn. It-tnejn isibu effetti reali fuq il-piż u l-markers kardjometaboliċi assoċjati, u t-tnejn huma kawti dwar id-daqs u ċ-ċertezza ta' dawk l-effetti.

Il-kavetta li terġa' tiġi: il-markers jtejjebu madwar proporzjon għall-piż mitluf. Il-provi li jqabblu l-fasting intermittenti ma' restrizzjoni kontinwa tal-enerġija fil-diabetes tat-tip 2 sabu riżultati komparabbli [4], li huwa dak li tistenna jekk il-mekkaniżmu hu l-defiċit.

It-titjib fil-glycaemic

Il-provi tad-diabetes

Il-prova EARLY hi l-aktar interessanti klinikament: dieta ta' sostituzzjoni tal-meal 5:2 ta' fasting intermittenti testata għall-kontroll tal-glycaemic fl-adulti b'diabetes, bil-HbA1c bħala l-punt finali [6]. Is-sostituzzjoni tal-meal tneħħi ħafna mill-problema ta' aderenza, li jista' jkun għaliex ir-riżultat kien pożittiv.

Komparazzjoni randomizzata ta' 16:8 kontra 14:10 u grupp ta' kontroll rapportat fuq it-tnaqqis tal-piż u parametri metaboliċi [8], li jsaħħu li l-lunghezza tal-finestra mhix l-ingredjent attiv.

L-età għandha importanza

Reviżjoni li eżamina speċifikament ir-riskji u l-benefiċċji tal-fasting intermittenti għall-ġisem kardjovaskulari li qed jiżdied [3] hi ta' valur jekk inti iktar minn 60. L-adulti akbar għandhom inqas massa ħadra li jitilfu, aktar interazzjonijiet tal-mediċini, u ċ-ċans akbar li perjodu ta' intake mnaqqsa jproduċi problemi li jkunu trivjali meta jkunu 30. Prova ta' Cell Metabolism li tkejjel ir-risposti tal-moħħ għall-fasting intermittenti kontra dieta ta' ħajja tajba fl-adulti akbar [7] hi waħda mill-ftit studji mfassla għal din il-popolazzjoni.

X'jidhirlu li ma jżommx

  • "Il-fasting jerġa' jreġġa' l-insulina b'mod indipendenti mill-telf ta' piż." Mhux stabbilit. Il-provi li qabbdu bidla fil-piż ma juru l-ebda effett ċar indipendenti.
  • "Il-fasting jissolvi l-kolesterol tiegħek." Il-lipidi jmovew bil-piż u l-kompożizzjoni tal-dieta. Il-fasting per se m'għandux effett stabbilit speċifiku fuq il-lipidi.
  • "Il-fasting inaqqas l-infjammazjoni." Il-markers infjammatorji jaqgħu ma' telf ta' xaħam. Attribwixxejn dak għall-pattern tal-fasting jeħtieġ kontroll li l-biċċa l-kbira tal-provi m'għandhomx.
  • "Inti se ssir adattat għall-xaħam u tburnja xaħam matul il-ġurnata." L-użu ta' sussidju jinbidel waqt il-fasting u jerġa' jinbidel wara li tiekol. L-ossidazzjoni tal-xaħam ta' 24 siegħa hi mmexxija mill-bilanċ tal-enerġija.

Mistoqsijiet komuni

Se jerġa' l-fasting l-prediabetes tiegħi?
It-telf ta' piż inaqqas b'mod sostanzjali l-progressjoni lejn id-diabetes tat-tip 2, u l-fasting hu mod wieħed biex tinkiseb telf ta' piż. M'hemm l-ebda evidenza li hu aħjar minn rotot oħra għall-istess telf.
Jekk ir-readings tal-glukoża tiegħi waqt il-fasting qed jiżdiedu jfisser li mhux qed jaħdem?
Il-glukoża waqt il-fasting tista' tiżdied transitorjament waqt il-fasting estiż hekk kif il-liver iżomm is-supply. Mhuwiex waħdu sinjal ta' ħsara, iżda diskuti kwalunkwe readings inaspettati ma' klinik.
Huwa tajjeb il-fasting għall-kolesterol?
Indirettament, permezz tat-telf ta' piż u spiss permezz ta' titjib fil-kwalità tad-dieta. L-ebda effett speċifiku fuq il-lipidi ma hu stabbilit.
Nista' nfastja bil-diabetes tat-tip 2?
Il-provi għamlu dan b'mod sikur taħt supervisjoni, inkluż fil-pazjenti trattati b'insulina. Tagħmel dan mingħajr aġġustament tal-mediċina hi l-parti perikoluża — ara safety.
