Take Home Message
Out of the twelve, these are the clear winners, with the first substantial proof to back them up:
Weight loss: Glucomannan, CLA, and Orlistat (Alli)
Increased fat burning: caffeine and tea extract
However, I have to advise against Orlistat thanks to the unpleasant facet effects, and against CLA thanks to the harmful effects on metabolic health.
That leaves the U.S.A. with glucomannan, green tea extract, and caffeine.
These supplements may be helpful. However, the results are modest at best.
Unfortunately, NO supplement or pill works that well for weight loss.
They may provide your metabolism a touch of a nudge and assist you to lose many pounds. However, that's wherever it ends, sadly
Cutting carbs and feeding additional supermolecule are still the most straightforward ways to reduce, and work higher than all the diet pills combined.
