What is the role of guarana in weight loss?

Guarana is a plant that contains caffeine, which plays a significant role in increasing energy expenditure. When consumed, guarana can enhance metabolic rate by stimulating the central nervous system. This stimulation leads to increased thermogenesis and fat oxidation, therefore promoting energy mobilization and utilization during physical activity. As a result, individuals may experience greater calorie burn, which can be beneficial in weight loss efforts.

Additionally, the caffeine in guarana may improve exercise performance by enhancing endurance and reducing the perception of exertion, allowing individuals to engage in more intense physical activity. This also contributes to a higher overall energy expenditure. Therefore, guarana's primary role in weight loss is associated with its capacity to boost energy expenditure rather than directly influencing factors like hunger or digestion, making it relevant in the context of weight management strategies.
