April 23, 2014 – A new kind of Jenny Craig diet formulated specifically to help people manage their Type 2 diabetes has demonstrated its effectiveness in a new clinical trial — so much so, that the commercial weight-loss company launched a new program based on the study’s findings. The study’s lead researcher was Cheryl Rock, Ph.D., R.D., a professor of preventive medicine at UC San Diego Medical School. The study, funded by Jenny Craig, was published in the American Diabetes Associations’ journal Diabetes Care.
