Metabo Speed XXX Fat Burner Review

Sounding more like something sold to you on a dark corner by a guy in a trenchcoat than a fat burner, Metabo Speed XXX is the "celebrity diet pill."

That's according to the Web site advertising anyway.

Whether it is or not is a different story, because I don't see any verifiable proof that celebrities are using it... and really, so what if they are? Since when have big name Hollywood types done anything but jump from one ridiculous fad diet to another?

That said, the sales hype for the Metabo Speed XXX fat burner is fairly tame compared to some of the ones I've reviewed lately. Regardless, their claims that their product will help you "burn fat faster", and "trim down quickly" are not verified by any double-blind, placebo controlled, independent, peer reviewed studies.

And the formula itself, while not the worst I've seen, is hardly ground breaking. What's in it?...

1) Bitter Orange: standardized for synephrine, ephedra's "chemical cousin," it was originally thought synephrine could replace ephedra as the premier thermogenic in most fat burner compilations (this based on promising animal studies). Unfortunately, human-based studies have been less exciting. Results were lackluster, they suffered from methodological flaws, or were done using a combination of ingredients (making it impossible to attribute results to any specific ingredient).

2) Guarana extract: a useful ingredient in fat burners, but this is largely because guarana is a source of caffeine -- which in itself is a useful thermogenic agent.

3) Proprietary blend: this small 160 mg/dose blend contains a blend of green tea, vanadium, garcinia cambogia, ginseng, and a few other ingredients (bee pollen and white willow bark).

Green tea (reviewed here) is a welcome addition to any fat burner because of its demonstrated ability to elevate the metabolism and inhibit the action of the enzyme amylase. Unfortunately, because the exact amount of green tea in this formula is hidden by its inclusion in the proprietary formula, it's hard to determine whether or nor there's enough here to elicit any sort of positive response.

Garcinia cambogia (standardized for hydroxycitric acid and reviewed here) was once thought to be a useful "carb blocker." New research has pretty much dumped all over this (results proved to be inconclusive for weight loss) and it's only the new "super citrimax" version of garcinia that is showing any promise.

Vanadium is useful as a blood sugar moderator, but again, it's hard to know how much of it there is in this formula.

Metabo Speed XXX also contains phosphates -- which in one study were combined with garcinia cambogia, l-tyrosine and guggulsterones to yield modest weight loss. Unfortunately, both the l-tyrosine and the guggulsterones are absent from this formula.

In the end, I'd say the Metabo Speed XXX fat burner is in need of a revamp. The newest research really hasn't borne out promising results for either bitter orange or garcinia cambogia. Ingredients like these should be dumped and the amount of ingredient that show real promise ( like green tea) should be increased.

And Lab 88, the makers of Metabo Speed XXX, needs to get some ethics and credibility.
