Yerba mate (Ilex paraguariensis) is a traditional South American beverage that has been consumed for centuries, often for its stimulating effects. In recent years, scientific interest has grown regarding its potential role in supporting weight loss. Several studies suggest that yerba mate may contribute modestly to weight management, primarily through mechanisms such as appetite suppression, increased fat oxidation, and enhanced energy expenditure. For example, clinical trials have shown that yerba mate extracts can reduce food intake and delay gastric emptying, which may contribute to feelings of fullness. Additionally, some research indicates that yerba mate increases thermogenesis and the oxidation of fat, likely due to its caffeine and polyphenol content.

However, the overall quality of the evidence is low to moderate, with most human studies being short-term, of small sample size, or using mate extracts rather than traditional brewed tea. Meta-analyses suggest a minor, but statistically significant, effect on body weight and fat mass when yerba mate is consumed regularly in combination with other lifestyle changes. Importantly, yerba mate is not a magic bullet for weight loss, and its effects are much less pronounced than those seen with established interventions such as dietary modification and exercise. In summary, while there is some scientific evidence supporting yerba mate’s role in weight loss, the strength of the evidence is limited and further well-designed clinical trials are needed to confirm these findings.
