For years I have been propagating tongkat ali in high dosages for weight loss.
Now somebody patented this idea in the US.

That water-based tongkat ali extract changes body composition in men from fat to lean body mass has been confirmed in a human clinical trial.
This study was published in the Britisch Journal of Sports Medicine.
The scientific index for this study is:

The study was made with men. However, it is known that testosterone modulation has a greater effect on women than it does on men. Therefore, it is likely that if tongkat ali water-based extract causes fat loss in men, it will do so more dramatically in women.
However, those intending to use tongkat ali for weight loss should be aware that the tongkat ali available in health food stores in Western countries is low-ratio and low-quality, and that a lot of the extract sold on Internet spam sites is fake, and/or mixed with cheap other stuff.
