Evidence-Based Benefits
- Meta-analysis findings — Onakpoya et al. (2011, 12 RCTs, n=706) found a small mean difference in weight loss (-0.88 kg) favoring HCA, but results were not statistically significant when rigorous trials were analyzed
- Appetite reduction — some studies report modest appetite suppression, possibly through serotonin modulation in the brain
- Lipogenesis inhibition — HCA inhibits ATP-citrate lyase in vitro, theoretically reducing de novo fat synthesis (though this pathway is minor in humans on normal diets)
- Blood lipid effects — some trials report modest triglyceride and cholesterol reductions
