## What The Sources Report

- Dysregulated adipogenesis in obesity involves excessive preadipocyte recruitment and differentiation, leading to increased adipocyte number (hyperplasia) and hypertrophy. [Marie Ohoud M. (2026); evidence level 3]
- In obesity, lipolytic capacity is suppressed through multiple mechanisms including impaired sympathetic nervous system signaling and reduced expression of lipolytic enzymes (Thorp and Schlaich ). [Marie Ohoud M. (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

For green tea extract weight loss randomized trial, the current source set is useful for orientation, but it is not yet broad enough for strong claims. Use cautious language and keep conclusions close to the cited sources.

## Limits Of This First Pass
