From Fat Oxidation to Appetite Control
Several clinical trials have shown that yerba mate helps stimulate fat oxidation, even during moderate physical activity. It activates AMPK, an enzyme known to promote cellular energy efficiency and mitochondrial biogenesis. In practical terms, this means yerba mate not only helps the body burn fat more effectively but also supports the cells’ ability to create and manage energy.
Yerba mate also reduces appetite through a lesser-known pathway: bitter taste receptors. Found not only on the tongue but also in the digestive system and even fat cells, these receptors respond to bitter compounds by triggering hormones like CCK, PYY, and GLP-1—all of which curb hunger and improve glucose regulation.
GLP-1 and Thermogenesis: Beyond the Buzz
GLP-1 is one of the body’s most powerful satiety and insulin-regulating hormones, and yerba mate appears to stimulate it both directly and indirectly. Animal studies suggest yerba mate promotes GLP-1 secretion and even improves the gut microbiome’s ability to support this process. Additionally, its thermogenic effects in brown and beige fat tissue may contribute to improved energy expenditure and long-term weight maintenance.
Studies also point to yerba mate’s protective role in the liver, where it helps balance redox states and reduce oxidative stress—adding to its reputation as a metabolic support beverage.
Should You Switch from Coffee?
While both coffee and yerba mate offer health benefits, yerba mate may hold an edge in the metabolic realm. It provides gentler stimulation, a broader array of polyphenols, and more direct interaction with fat metabolism and appetite regulation. For those looking to support fat loss, manage blood sugar, or improve metabolic flexibility, yerba mate offers a natural and evidence-backed alternative.
Ben’s Favorite Yerba Mate
As a final note, my preferred source of yerba mate is Unimate by Unicity. In full disclosure, I serve as a scientific advisor to the company, though that relationship developed after I had already become a regular consumer of the product. What distinguishes Unimate is its purity and potency—it’s derived from hand-harvested leaves grown at high altitude and processed using a patented extraction that concentrates chlorogenic acids while minimizing smoke-related contaminants.
