Clinical studies indicate that consuming Celsius energy drinks increases resting energy expenditure and markers of lipolysis, supporting claims that they assist with metabolic rate and fat burning.
The provided literature specifically evaluating Celsius and related thermogenic fitness drinks (papers [2] and [3]) demonstrates increases in resting energy expenditure (REE) and elevated free-fatty acid (FFA) or glycerol concentrations, indicating enhanced lipolysis. Because the direct evidence supports the claim and there is no refuting evidence among the provided sources, the balance verdict is SUPPORTED.
