Cochrane review of 14 RCTs found EGCG plus caffeine produces modest but statistically significant weight loss of 1.0-1.3 kg over 12 weeks. Twenty-four-hour energy expenditure increased approximately 5% and fat oxidation approximately 16%, with effects more pronounced in Asian populations and habitual low-caffeine consumers.
