Clinical outcomes

Peer-reviewed research evaluating the effect of Virta demonstrates that patients can safely improve health outcomes associated with type 2 diabetes, obesity, atherogenic dyslipidemia, hypertension, and inflammation. By impacting these chronic conditions, Virta improves several risk factors for type 2 diabetes and cardiovascular disease.

Type 2 Diabetes

While reducing and eliminating glycemic control medications, Virta patients lowered HbA1c by 1.3% on average after one year and improved insulin resistance measured by HOMA-IR. 60% of patients enrolled one year attained an HbA1c below 6.5% without the use of diabetes medications other than metformin.¹

Obesity

Excess weight represents risk for both type 2 diabetes and cardiovascular disease. Virta patients with type 2 diabetes sustained the loss of 12% of their body weight over the year. The prevalence of class III obesity among participants was reduced from 46% to 20%.¹

Atherogenic Dyslipidemia

Characterized by high triglycerides and low HDL-C, atherogenic dyslipidemia is common among patients with insulin resistance and represents increased cardiovascular risk. Virta patients improved both markers, with the TG/HDL-C ratio declining from 4.7 to 3 on average.¹

Hypertension

Elevated blood pressure, especially in the presence of additional risk factors, increases cardiovascular risk. Virta patients reduced blood pressure and the need for antihypertensive medication, especially diuretics.¹

Inflammation

Inflammation is a common underlying factor in obesity, insulin resistance, hypertension, and cardiovascular disease. C-reactive protein and white blood cell count, common markers of inflammation, were significantly reduced in Virta patients with type 2 diabetes.¹

Safety

A common concern in the treatment of type 2 diabetes is hypoglycemia. In our clinical trial, no hypoglycemic events requiring assistance were reported. Additionally, treatment at Virta resulted in neutral or positive effects on markers of kidney and liver function.¹

Cardiovascular Risk Measures

10-year ASCVD risk score improves after one year of the Virta Treatment. Most lipid and lipoprotein risk markers improved or were unaffected; an undesirable change was observed in one marker.¹

Veterans using Virta’s remote ketogenic program sustain metabolic improvements for 3 years

In a 3-year observational study, U.S. veterans with type 2 diabetes saw durable HbA1c reduction (–0.8%), 9% weight loss, decreased diabetes medication use, and improved cardiometabolic markers. These results support Virta’s model as a long-term solution for chronic disease in high-risk populations.

Virta’s ketogenic care model may stabilize kidney function and lower inflammation in type 2 diabetes

In a post-hoc analysis of a two-year intervention, people with type 2 diabetes and reduced kidney function (eGFR <90) saw improved eGFR slopes and reduced inflammatory markers. Higher ketone levels were linked to greater renal benefits, supporting the safety of Virta’s approach in early-stage CKD.

Blood glucose meters perform as well as CGMs in Virta’s nutrition-based diabetes care

At 6 months in a randomized trial of people with type 2 diabetes following a carbohydrate-restricted nutrition program, both CGM and BGM users had similar HbA1c reductions (–1.3%) and improved time in range (from 61% to 87% for CGM, 63% to 88% for BGM). Both groups also lost weight. These findings suggest BGM may be sufficient for glycemic improvements in structured interventions.

Exploring the Potential of Nutritional Ketosis in Preserving Lean Mass

Weight loss (WL) is important for managing obesity and type 2 diabetes, but preserving lean body mass (LBM) during WL is also a key consideration. Preliminary post-hoc analyses from the Virta trial suggest that participants experienced minimal lean mass loss during weight loss, aligning with the Quarter Fat-Free Mass ratio benchmark of a 3:1 fat-to-lean mass ratio. Participants also showed improvements in physical function. Additionally, the data indicate that higher ketosis levels may be associated with better lean mass preservation, with a potential dose-response relationship observed.

Virta’s care model supports better weight loss and medication reduction when added to rural community diabetes programs

In a Colorado pilot study of adults with type 2 diabetes, both groups—community health support alone and combined with Virta’s continuous remote care—had significant HbA1c reductions (–1.2% and –1.5%). However, only the Virta group saw significantly greater ≥5% weight loss and medication burden reduction. These findings support integrating Virta’s model into rural programs to enhance outcomes.

Five Years of Sustained Cardiometabolic Improvements and Diabetes Remission Maintenance

Virta trial participants who remained in the study for five years demonstrated long-term improvements in body mass, triglycerides, fasting insulin, and HbA1c, along with an increase in HDL cholesterol. Results showed that 20% of participants achieved diabetes remission, with 15.8% maintaining remission at three years and 12.5% at five years. Among those who completed the five-year follow-up, 61.3% sustained at least 5% weight loss, while 39.5% maintained a 10% weight loss. These findings underscore that sustained diabetes remission is achievable and can have a meaningful impact on long-term diabetes management and outcomes.

Reduced COVID severity with weight loss on Virta

Among the risk factors for severe COVID-19 infection and death include type 2 diabetes and obesity, both of which Virta has demonstrated to favorably impact.

Evidence of non-alcoholic fatty liver disease improvement

The only treatment currently endorsed by professional guidelines for non-alcoholic fatty liver disease (NAFLD) is weight loss. At one year, Virta patients on average lost 12% of body weight. Nearly 4 out of 5 patients lost more than 5% of their starting weight, which is associated with improvement in steatosis.

One-year sleep improvement in type 2 diabetes and prediabetes

People with T2D and prediabetes are more likely to experience some kind of sleep disturbance. The interrelationship between sleep and metabolic disease not only affects quality of life but also worsens insulin resistance and other cardiometabolic outcomes. Virta patients improved global sleep score after one year of treatment with 14.0% and 20.7% improvements in T2D and prediabetes, respectively.
