Results not typical. In a study performed in 2012 by University of Illinois at Chicago researchers, subjects lost an average of 9 pounds with an average of 2 pounds of the loss from visceral fat after 30 days on an Isagenix System. The subjects also had a greater level of adherence and had more consistent weight loss from week to week compared to subjects on a traditional diet.
In a two-phase study performed in 2015-16 by Skidmore College, Saratoga Springs, New York, researchers evaluated use of Isagenix products for weight loss followed by weight maintenance. As part of the weight-loss phase, the participants took part in a calorie-controlled regimen of Shake Days and one Cleanse Day per week and lost an average of 24 pounds after 12 weeks. During the weight-maintenance phase, the subjects who continued the calorie-controlled program using Isagenix products better maintained their weight loss in comparison to those who transitioned to a traditional diet after 52 weeks.
