Study: Lark’s Diabetes Prevention Program Shows Long-Term Weight Loss Results

March 3, 2020
One-Year Clinical Outcomes Demonstrate Platform’s Ability to Engage and Impact Adults at Risk of Type 2 Diabetes

MOUNTAIN VIEW, CALIF. (March 3, 2020) — Lark Health, the leading chronic disease management and prevention platform, today released a year-long study of its digital Diabetes Prevention Program (DPP), finding it produced positive clinical outcomes for adults at-risk for type 2 diabetes. Study participants using Lark’s Fully CDC-Recognized DPP experienced an average weight loss of 10 pounds, or an average loss of 4.2 percent of body weight, after completing the year-long program. 

“This study demonstrates Lark’s ability to help at-risk adults achieve long-term, clinically significant weight loss and reduce their risk of developing type 2 diabetes,” said Dr. Jason Paruthi, MD, Medical Director at Lark. “Lark’s coaching program, utilizing AI and connected devices, can reach millions of adults who otherwise might not have access to an in-person or telephonic DPP and provide them with highly effective coaching and guidance.”

Six-hundred and ten (610) participants, with a mean age of 47 years were identified as eligible for the Lark DPP based on CDC criteria of being at-risk for type 2 diabetes. Eligible participants were prompted to enroll in the Lark DPP and were shipped a digitally connected weight scale. The Lark DPP is an engaging, highly personalized program that delivers the CDC Prevent T2 curriculum via a series of 26 weekly missions followed by a maintenance period.

In addition to overall weight loss at one year, Lark’s research team noted exceptional program engagement. After one year, study participants achieved a mean weight loss of 4.2 percent, while 40 percent of participants achieved a weight loss of at least 5 percent. Participants averaged 393 coaching sessions and 182 weight measurements. 

Weight loss is used as a clinical proxy for DPP program effectiveness, as obesity is closely related to insulin sensitivity, blood glucose control, and risk for type 2 diabetes. Sustained weight loss at one year has been clinically proven to reduce the risk of type 2 diabetes, according to the International Journal of Clinical Practice, while a study in Diabetes Care concluded that each kilogram lost correlates with a 16 percent lower risk for type 2 diabetes. Further, health care cost savings for someone without obesity compared to someone who has obesity are estimated at $1,440 annually, while taking the CDC estimate of obesity in adults at 39.8 percent in 2015-2016, a company with 10,000 employees whose employees with obesity used the Lark DPP could potentially save over $600,000 annually.

Lark’s technology, and specifically the use of AI, allows the platform to serve millions of members, wherever they are and whenever they need it, with non-linear increases in cost.  For instance, each of the meals logged by a participant are followed by instantaneous coaching on meal quality and trends using AI and Natural Language Processing. Lark’s platform breaks down barriers typically experienced in in-person and telephonic DPPs including cost, lack of coverage, and the inability to scale outcomes to the tens of millions of Americans at risk for type 2 diabetes.
