Drs. Joy Frestedt and John Zenk (Minnesota Applied Research Center, Edina, MN), Michael Kuskowski (Geriatric Research Education and Clinical Center, Minneapolis, MN), and Loren Ward and Eric Bastian (Glanbia Research and Development Center, Twin Falls, ID) conducted this 12-week study on healthy subjects on a diet that reduced caloric intake by 500 calories/day. They showed that subjects who consumed a flavored and sweetened drink mix that contained the same peptide blend in OsoLean® powder lost significantly more body fat and lost less lean muscle mass when compared with those consuming an isocaloric beverage.*
