The effects of anthocyanins on body weight and expression of adipocyte’s hormones: Leptin and adiponectin

[Display omitted] •Obesity results in adipose tissue dysfunction.•Anthocyanin-rich QGPJ significantly decreases body weight and BMI after 4 weeks.•QGPJ significantly increases adiponectin and decreases leptin blood levels.•QGPJ may be used as a functional food factor for preventing obesity. The purpose of the study was to assess the effects of anthocyanin-rich Queen Garnet plum juice (QGPJ) on body weight and expression of leptin and adiponectin. Queen Garnet plum is a Japanese plum (Prunus salicina) cultivar developed through a Queensland Government breeding program with very high levels of anthocyanins (272 mg/100 g). Twenty healthy volunteers were supplemented with 200 ml/day of QGPJ and placebo drink for 4 weeks. Supplementation with QGPJ significantly reduces body weight and BMI (p
