Cis-9,Trans-11 vad är det? "Gain 700% More Muscle in 7 Weeks... Guaranteed!"

[qazwsx]

vad tror ni om Cis-9,Trans-11 och vad exakt är det?

"Gain 700% More Muscle in 7 Weeks... Guaranteed!"

skit snack eller kan det stämma?

[frong]

Garanterat skitsnack utan att jag behöver läsa något.

Så, om du väger 70 nu, muskler på.. 30kg? så kommer du väga 280 snart?

Or am I wrong?

[Sverker]

CLA. Konjugerande fettsyror.

Du kommer inte att få några överdrivna resultat. Du får söka.

[Eddie Vedder]

Det där är CLA, en transfettsyra som är populär i kosttillskottssammanhang. Dess fördelar är omdiskuterade och studierna ganska motsägande.

Postivt eller ej så är det där påståendet rent skitsnack givetvis.

[stridis]

Antagligen menar de 700% mer muskler på 7 veckor än vad du skulle byggt utan.

[Ganymedes]

Antagligen menar de 700% mer muskler på 7 veckor än vad du skulle byggt utan.

"Utan" som i "utan att träna". Fast inte ens då tror jag på det. :)

[stridis]

Visst är det bs-påstående men hans uttydning av påståendet är löjligt.

[qazwsx]

så det är inget o köpa alltså... slöseri på pengar

[King Grub]

CLA är inte nödvändigtvis bortkastade pengar, men effekterna på muskeluppbyggnad och fettförbränning är mycket, mycket mer blygsamma än den där reklamen utlovar.

PURPOSE OF REVIEW: This review critically evaluates studies investigating the effects of conjugated linoleic acid on human health, including effects on body composition, blood lipids, liver metabolism, insulin sensitivity and immune function. It focuses mainly on human intervention studies, but includes some reference to animal and cellular studies which provide insight into potential molecular mechanisms of action of conjugated linoleic acid. RECENT FINDINGS: Human studies continue to report inconsistent effects of conjugated linoleic acid on human health. Some of these reports are based on overinterpretation of marginal effects of supplementation. Recent data suggest that the effects of the substance may be isomer dependent and that cis-9,trans-11 and trans-10,cis-12 conjugated linoleic acids have opposing effects on blood lipids and on metabolism in adipocytes and hepatic cells. SUMMARY: Claims that conjugated linoleic acid is beneficial for health remain as yet unconvincing. Human studies investigating the effects of conjugated linoleic acid supplements have tended to use mixtures of isomers and have been inconsistent. More recent studies have attempted to use relatively pure preparations of single isomers and these studies suggest that the effects of conjugated linoleic acid may be isomer-specific. These recent data suggest a relative detrimental effect of trans-10,cis-12 conjugated linoleic acid on blood lipids. There appears to be little effect of conjugated linoleic acid on immune function and the effects on insulin sensitivity remain unclear.

Conjugated linoleic acid and human health: a critical evaluation of the evidence. Curr Opin Clin Nutr Metab Care. 2006 Mar;9(2):105-10.

BACKGROUND: Conjugated linoleic acid (CLA) has been shown to be an effective supplement for reducing fat mass in animals, whereas results in humans have been inconsistent. OBJECTIVE: This is a meta-analysis of human studies in which CLA was provided as a dietary supplement to test its efficacy in reducing fat mass. DESIGN: We searched the PubMed database (National Library of Medicine, Bethesda, MD) and references from the resulting search to identify studies in which CLA was provided to humans in randomized, double-blinded, placebo-controlled trials and in which body composition was assessed by using a validated technique. RESULTS: We identified 18 eligible studies. Of these, 3 were single-isomer studies, and results comparing CLA isomers were inconclusive. We compared the length of treatment by using studies in which a mixture of purified isomers were used and those in which purified trans-10,cis-12 isomers were used. This comparison indicated that the effect of CLA was linear for up to 6 mo and then slowly approached an asymptote at 2 y. An analysis of the dose effect indicated that fat loss compared with placebo was -0.024 kg x g CLA(-1) x wk(-1) (P=0.03). After adjustment to the median dose of 3.2 g CLA/d, CLA was effective and produced a reduction in fat mass for the CLA group alone (0.05 +/- 0.05 kg/wk; P<0.001) and for the CLA group compared with placebo (0.09 +/- 0.08 kg/wk; P<0.001) CONCLUSION: Given at a dose of 3.2 g/d, CLA produces a modest loss in body fat in humans.
