Published in International Journal of Obesity
Methodology
Meta-analysis of 11 randomised controlled trials examining catechin-caffeine mixtures on body weight and weight maintenance
Key Findings
Catechin-caffeine mixtures produced a small but significant reduction in body weight (about 1.31 kg); habitual high caffeine intake blunted the effect.
Conclusions
Any thermogenic benefit of green tea depends on combined catechin and caffeine intake and is modest.
Limitations
Publication bias possible; effect confounded by caffeine habituation.
Supplements Studied
Catechin-caffeine mixtures produced a small but significant decrease in body weight, an effect blunted by high habitual caffeine intake.
Outcomes Measured
Catechin-caffeine mixtures produced a small but significant reduction in body weight, blunted by high habitual caffeine intake.
