A traditional South American's drink that's said to have the strength of coffee, health benefits of tea and taste of chocolate.

Several human studies suggest that it can increase the amount of stored fat that's burned for fuel (1, 2).

In a 12-week study by BMC Complementary and Alternative Medicine, overweight people who took 3 grams of yerba mate powder per day, lost an average of 1.5 pounds (0.7 kg) and reduced their waste-to-hip ratio by 2%, while placebo group gained an average of 6.2 pounds (2.8 kg) and increased their waste-to-hip ratio by 1%.

Yerba mate may help you curb appetite, boost metabolism and increased the amount of fat burned for energy, says


Also known as Paullinia Cupana, a Brazilian plant native to the Amazon basin. It contains a handful range of stimulants such as caffeine, theophylline and theobromine. That said, guarana may help in promoting weight loss.

Test tube studies have found that guarana may suppress genes that directly aid in fat cell production and accelerate genes that slow it down (3, 4).

However, its effect on fat cell production remained unclear in humans. More human studies are needed, states

Trimethylxanthine (Caffeine)

Trimethylxanthine is the scientific name of caffeine.


Damiana is commonly used by mouth to increase sexual desires and treating erectile problems, but no research support any of such uses, reports WebMD.

Green Tea

Green tea has been making a headline for association with numerous health benefits, especially weight loss, due to its rich nutritional and antioxidant properties.

A recent study by Cochrane Library, investigated the clinical use of green tea to trigger weight loss in overweight people. In conclusion, it was found that green tea has a positive impact on weight loss but the result wasn't so noticeable. Even though, the author of the study concluded, it's unlikely to be of any clinical importance.

According to Medical News Today, the benefits of green tea on weight loss are likely to be very small. Its impact on weight loss isn't so beneficial that it could replace the other benefits of weight loss such as diet and exercise.

Kola Seed

Kola nut is used for short-term relief from fatigue, depression, atonic diarrhea and migraine headaches, mentions


Schizonepeta tenuifolia is a herb commonly known as Japanese Catnip of Jing Jie that's traditionally used as a remedy for common colds, head colds and allergic skin eruptions, but no scientific studies support any of such uses, reports

Black Pepper

According to LiveStrong, black pepper won't help you lose belly fat, while some studies indicate it helps in fighting obesity, other studies failed to show any weight loss benefit. So, don't count black pepper as a weight loss cure, instead use it as a source of flavor in your weight loss diets.

Rhodiola Crenulata

A clinical study by Bulletin of Experimental Biology and Medicine, investigated the effects of oral treatments on the duration of exhaustive swimming and ATP content in mitochondria of skeletal muscles in rats with Rhodiola rosea (50 mg) and Rhodiola crenulata (50 mg).

In conclusion, it was found that Rhodiola rosea is most effective for improving physical working capacity.

Asian Ginseng

Also known as Korean Ginseng, may help to regulate insulin levels, improve controls over blood pressure and improves energy levels. However, when it comes to losing weight, no research date has proven its effectiveness for weight loss purposes, says,

Maca Root

Maca has been traditionally used for its ability to increase fertility and sex drive, especially in men. Although maca isn't linked to losing weight, its healing capabilities may help to promote a decrease in body weight, reports LiveStrong.


According to Healthline, cacao and cacao-rich products may be helpful in achieving or maintaining body weight, but further studies are needed what type of and how much cacao is ideal.

Black Tea

Black tea is packed with nutrients and it's just another rich source of caffeine and antioxidants.

Not a quick weight loss product but it works. Eat my meals and don't snack in between.
Great for an energy boost. I didn't lose a single pound of weight though. I took them as directed for a whole month too.
Billie D Stamm
The first night I took this I was fine. The second time I took it I broke out in a horrid burning rash that spread all over my body. I am not allergic to anything but my body acted as if it was an allergic reaction. After taking it I also felt dizzy and nauseous. I had to be rushed to the hospital. DO NOT USE.
