Abstract
PURPOSE: Overweight and obesity contribute to the development of cardiovascular, neurocognitive, and metabolic diseases. One approach that has recently gained popularity in combating overweight and obesity is the consumption of energy or thermogenic beverages, owing to their proposed ability to boost metabolism and increase fat burning. However, whether Reign Storm Valencia Orange can exert positive effects remains unknown. This study hypothesized that consumption of Reign Storm Valencia Orange would acutely increase energy expenditure and fat utilization relative to water consumption. METHODS: Thirty-two individuals (17 females and 15 males) participated in this study. Arterial blood pressure, normalized oxygen consumption, resting energy expenditure (REE), and respiratory exchange ratio (RER) were assessed during rest at baseline and at 30, 60, 90, and 120 minutes after beverage consumption (randomized order). RESULTS: Arterial pressure was elevated following beverage consumption (main effect of time, p < 0.05), with no significant difference between the conditions (main effect of beverage, p > 0.15). Normalized oxygen consumption and REE were elevated following beverage consumption (main effect of time; p < 0.01 for both) with a significant interaction (p < 0.01 for both), indicating a greater impact of Reign Storm Valencia Orange. RER was reduced following beverage consumption (main effect of time; p < 0.0001), with a significant interaction (p < 0.0001), indicating a greater impact of the Reign Storm Valencia Orange condition. Consumption of Reign Storm Orange Valencia had a beneficial impact on indices of resting energy expenditure and metabolism and resulted in greater reliance on fats. CONCLUSION: Accordingly, Reign Storm beverages, in combination with other modifiable lifestyle behaviors such as exercise and a healthy diet, can potentially assist in losing body weight and burning fat.
