Zeleni čaj in podobni dodatki kurijo maščobe

Kaj dokazi dejansko kažejo

Meta-analize pripravkov katehinov in kofeina ugotavljajo učinke na težo, ki so statistično zaznavni in klinično nepomembni — delček kilograma. ^[1]

Zakaj trditev vztraja

Kofein dejansko akutno povečuje porabo energije. Velikost nikoli ne doseže tistega, kar embalaža implicira.

Ta trditev je večinoma napačna. Skoraj nobena od teh ni preprosto napačna, kar je pravzaprav razlog, da vztrajajo — vsaka ima resno opazovanje pod napačnim zaključkom, in poimenovanje resničnega dela je tisto, kar naredi popravek verodostojen. Sodbe dodeljene iz citirane literature.

Druge trditve

"Vaša presnova se upočasni po 30" — večinoma napačno
"Pozno večerjanje vas naredi debele" — delno resnično
"Zajtrk pospeši vašo presnovo" — večinoma napačno
"Premalo hrane vas spravi v stanje lakote, zato prenehate izgubljati" — delno resnično
"Kilogram mišic kuri na stotine kalorij na dan" — večinoma napačno
"Neprekinjeni glukozni monitorji razkrivajo, katera hrana vam škoduje" — delno resnično

Ali je res, da zeleni čaj in podobni dodatki kurijo maščobe?

Večinoma napačno. Meta-analize pripravkov katehinov in kofeina ugotavljajo učinke na težo, ki so statistično zaznavni in klinično nepomembni — delček kilograma.

Torej, ali je v tem kaj resničnega?

Kofein dejansko akutno povečuje porabo energije. Velikost nikoli ne doseže tistega, kar embalaža implicira.

Kako se odločite o sodbi?

Tri ocene, ne dve. "Večinoma napačno" pomeni, da trditev, kot je navedena, ni podprta; "delno resnično" pomeni, da obstaja resničen učinek, vendar je manjši ali ožji, kot je navedeno; "večinoma resnično" pomeni, da jo dokazi podpirajo, kot je običajno navedeno.
