Chlorogenic acid composition and method of weight management

A method for modulating body weight comprising administering to a subject in need thereof a composition comprising a mixture of chlorogenic acids having (i) 4.1±1.42 w/w % 3-CQA, (ii) 28±4.65 w/w % 5-CQA, (iii) 6.5±2.25 w/w % 4-CQA, (iv) 0.84±0.26 w/w % 3,4-diCQA, (v) 1.23±0.34 w/w % 3,5-diCQA, and (vi) 1.85±0.42 w/w % 4,5-diCQA, wherein the mixture inhibits pancreatic lipase activity by about 44% at a concentration of about 100 μg/ml in vitro, and wherein administering the composition to the subject modulates body weight in the subject.
