Evidence Map

What The Sources Report

• Capsaicin was found to increase EE and fat oxidation, particularly at high doses, although results on the possible reduction in EI were mixed.In the present narrative review and updated meta-analysis, we evaluated whether culinary doses of RP can attenuate adaptive thermogenesis and decreased fullness during negative EB in humans. [Ludy Mary-Jon (2026); evidence level 3]
• Overall, long-term capsaicin consumption in free-living conditions did not provide statistically significant evidence for an EE increase but did significantly reduce RQ, suggesting sustained higher fat oxidation. [Ludy Mary-Jon (2026); evidence level 3]
• Gelidium Garcinia cambogia The World Health Organization defines overweight and obesity as abnormal or excessive fat accumulation that presents health risk to health. [Lee Hyeonseok (2026); evidence level 4]
• The prevalence of obesity in South Korea has steadily increased over the past decade, reaching approximately 38% in 2022, although the prevalence of severe obesity (body mass index [BMI] ≥ 40 kg/m) increased by 2.6-fold when compared with that in 2013. [Lee Hyeonseok (2026); evidence level 4]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation
