Ultimate iced tea for weight loss (not green tea!)
What is the best iced tea for weight loss? Swiss Scientists from the University of Fribourg have discovered that drinking your tea cold is twice as good for weight loss. But not just any tea, there is one iced tea that really stands out when it comes to weight loss, and that is Yerba mate tea. Studies have shown that drinking Yerba mate tea cold is more effective in breaking down of fat, than warm tea.
What is Yerba mate?
Yerba mate is a traditional South American drink, that is still very popular in many countries like Uruguay, Paraguay, Chile, and Argentina. It is very popular as a healthy alternative to coffee. In fact, Yerba mate tea is as strong as coffee and has more antioxidants than green tea. [1]
Burn more calories while resting
According to the study from the Swiss University of Fribourg, drinking Yerba mate tea could help burn more calories while resting. What is more, drinking Yerba mate tea cold, is much better at this than the usual warm tea. [2]
In the study, the volunteers had to drink 500 ml of unsweetened Yerba mate tea, which was either cold at 3°C (37°F) or hot at 55°C (131°F). The tea contained 99 mg of caffeine.
Throughout the experiment, the heart rate, blood pressure, oxygen consumption, carbon dioxide production, how much body heat is lost to the environment and other parameters were measured.
The researchers discovered that drinking Yerba mate tea increases energy expenditure. This means that people burned more calories while resting after drinking Yerba mate tea, compared to before drinking the tea.
Drinking cold tea increases energy expenditure more than warm tea. There was an +8.3% increase in energy expenditure after drinking the cold tea, compared to an +3.7% increase in energy expenditure after drinking the tea warm.
Cold Yerba mate tea increases fat oxidation
According to the same Swiss study, drinking Yerba mate tea does not only increase energy expenditure, but also fat oxidation. What is more, drinking Yerba mate tea cold, increased fat oxidation significantly more than warm tea. [2]
Another study from 1999 compared the effects of 12 different plants on fat oxidation.
The plants tested included the regular tea plant and Yerba mate.
From all the plants studied, only the Yerba mate extract managed to significantly increase fat oxidation. [4]
Fat oxidation is the process in which the fatty acids in your body are broken down in order to supply you with energy. Increased fat oxidation helps your body burn more fat. Exercise is well known to help boost fat oxidation as well.
Drinking tea cold aids weight loss
But does Yerba mate tea really help weight loss, or is it just the temperature of the beverage that helped increase energy expenditure and fat oxidation?
In order to answer this question, let’s see how Yerba mate tea compares to water. Does drinking cold water also help burn more calories?
It turns out, drinking cold water also helps with weight loss, but not as much as cold tea. According to another study, drinking 500 ml of cold water, instead of tea, increases energy expenditure with only +2.9%. [3] On the other side, cold Yerba mate tea increased energy expenditure with +8.3%, which is much better. [2]
So if you want to burn more calories while resting, you better drink your tea cold!

After 45 days the patients who received a supplement containing Yerba mate, Guarana, and Damiana, lost around 5kg (11lbs). On the other side, the patients who received placebo lost only around 0.3kg (0.6lbs). [5]
