The effects of bitter melon (Momordica charantia) on anthropometric indices in adults: A SR/MA of RCTs
結論：No significant effect on BW (WMD 0.04 kg, 95% CI -0.16 to 0.25, p=0.651), BMI (WMD -0.18 kg/m^2, 95% CI -0.43 to 0.07, p=0.171), WC (WMD -0.95 cm, 95% CI -3.05 to 1.16, p=0.372), or %BF (WMD -0.99, 95% CI -2.33 to 0.35, p=0.141).

The metabolic effect of Momordica charantia cannot be determined based on the available clinical evidence: SR/MA of RCTs
結論：No significant effect on body weight (MD -1.00 kg, 95% CI -2.59 to 0.59, I^2=97%), BMI (MD -0.42, 95% CI -0.99 to 0.14, I^2=95%), WC (MD 0.72 cm, 95% CI -3.36 to 4.80) or body fat (MD -1.21, 95% CI -2.62 to 0.20). Authors conclude metabolic effect 'cannot be determined' due to short trials, high heterogeneity, low evidence quality.

Effect of Momordica charantia on Anthropometric Measures and Metabolic Profile in Patients with Obesity: Pilot RCT
結論：No significant within- or between-group reductions in body weight, BMI, WC, or %BF in the MC arm at 12 weeks. Triglycerides and VLDL decreased significantly (p<=0.05). Placebo group gained weight/BMI. Small pilot.

mcIRBP-19 of Bitter Melon Peptide Effectively Regulates DM Patients' Blood Sugar Levels
結論：Improved fasting glucose/HbA1c in T2DM; trial did NOT report anthropometric/obesity endpoints as primary outcomes. The only peptide-specific human RCT identified — but evaluates diabetes, not obesity/weight.

📍立場總覽
台灣社群對苦瓜胜肽「減肥」普遍存疑：多數鄉民認為它本質是穩血糖、降三高保健品，瘦身效果應歸功於飲食控制與運動，吃了不會自己瘦。少數人回報飲食配合後體重下降，但他人多指出是變因混淆。業配以商業評比網站為主，PTT 討論串本身偏理性反業配。
💬社群實感
多數負面（社群普遍認為對減肥無直接幫助，效果來自飲食運動，苦瓜胜肽主要定位為穩血糖保健品）
破解迷思 社群最常見的 3 個誤解
✓
事實以為苦瓜胜肽是「吃了就會瘦」的減肥藥（鄉民澄清：沒有東西吃了就能瘦，需熱量赤字與運動）
✓
事實把改變飲食後的減重成果歸功於苦瓜胜肽（被指為一次換太多變因的無效實驗）
✓
事實誤以為它能直接燃脂（實際機轉是延緩醣類吸收、穩定血糖，非直接減脂）
