Pak-Dek MS, Abdul-Hamid A, Osman A, Soh CS.

Noni leaf extract inhibited lipoprotein lipase more than noni fruit extract and green tea extract. The inhibition of lipoprotein lipase increased as the concentration of the extracts increased. The results suggest that both noni leaf and fruit may be used as anti-obesity agents in body weight management.  (view original abstract at https://www.ncbi.nlm.nih.gov/pubmed/19019102).
