Summary

This study looks at whether a drink containing caffeine and green tea extracts can increase how much fat your body burns at rest, during exercise, and after a workout. Researchers will measure fat burning in 40 healthy adults aged 18 to 45 who exercise moderately. The goal is to see if this combination can help improve fat oxidation for better exercise results.
