If you’re living with Type 2 diabetes and your employer has offered you either Virta Health or Twin Health — or you’re weighing both independently — you’re looking at two of the most clinically credible digital diabetes reversal programmes available in the United States.
Both have peer-reviewed research. Both claim to reverse or put Type 2 diabetes into remission. Both are delivered entirely remotely through an app. And both are primarily available through employer health plans.
But they take fundamentally different approaches: Virta uses a medically-supervised ketogenic diet; Twin Health uses an AI-powered Digital Twin™ technology paired with continuous sensors. The clinical outcomes are different. The day-to-day experience is different. And the right choice depends on factors specific to you.
This article breaks down exactly how the two programmes compare — on clinical results, programme mechanics, cost, and who each is best suited for.

What Is Virta Health?
Virta Health was founded in 2014 and spent its first decade pioneering medically-supervised ketogenic therapy as a treatment for Type 2 diabetes — not as a weight-loss trend, but as a clinical intervention backed by peer-reviewed trials.
The programme works by placing participants on a very-low-carbohydrate (ketogenic) diet, supervised by a remote Virta physician who adjusts medications in real time as blood sugar improves. Members receive a dedicated health coach, a ketone meter to confirm nutritional ketosis, and access to the Virta app for daily check-ins.
As blood sugar drops — which it does rapidly on a carbohydrate-restricted diet for most participants — Virta physicians reduce or eliminate diabetes medications to prevent dangerous hypoglycaemia. That proactive medication management is what makes the programme medically meaningful rather than just dietary advice.
In 2024, Virta expanded into GLP-1 medication management, adding semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) as options for eligible members. Virta is now a broader metabolic health platform, not solely a keto programme — though the ketogenic pathway remains its core offering.
What Is Twin Health?
Twin Health was founded in 2018 in Menlo Park, California, and takes a markedly different technological approach. Rather than prescribing a single diet protocol, Twin Health builds a personalised AI Digital Twin™ of each member’s metabolism.
The Digital Twin is a real-time computational model that ingests data from continuous glucose monitors, wearable fitness trackers, smart scales, blood pressure cuffs, and other sensors. It analyses how that specific person’s body responds to food, activity, sleep, and stress — and generates personalised daily recommendations.
Twin’s approach is precision-first: because every person’s metabolic response is unique, Twin does not impose a single dietary protocol on all participants. Instead, it identifies the foods, meal timing, and activity patterns that work best for that individual’s physiology.
Members also get access to a clinical care team — physicians, dietitians, and health coaches — for human support alongside the AI guidance.
Twin Health has published research in the New England Journal of Medicine Catalyst (via a Cleveland Clinic-led randomised controlled trial), Nature Scientific Reports, The Lancet (pre-print), and the Journal of the American College of Cardiology, among others.
Clinical Results: The Evidence Side-by-Side
A1C and Diabetes Remission
The most clinically meaningful comparison is the rate of A1C remission — defined as HbA1c below 6.5% without diabetes medications (other than metformin).
Virta Health achieved a 1.3 percentage point average A1C reduction at 1 year (from 7.5% to 6.2% on average). 60% of participants enrolled for one year attained an HbA1c below 6.5% without diabetes-specific medications, meeting the clinical definition of remission. (Hallberg et al., Diabetes Therapy, 2018)
Twin Health reported that 71% of participants lowered A1C below 6.5% without glucose-lowering medications (except metformin), based on the 2025 Cleveland Clinic study published in NEJM Catalyst.
What this means in practice: Both programmes achieve remission rates that far exceed standard care (where roughly 2% of participants achieve remission). Twin Health’s headline figure is higher, but it’s important to note that the two studies used different populations, time points, and methodologies — direct apples-to-apples comparison is difficult. What both demonstrate is a clinically meaningful impact on A1C that medications alone typically cannot match.
Weight Loss
Virta Health participants lost an average of approximately 12% of body weight at 12 months — roughly 20–25 lbs for a 200-lb individual.
Twin Health reports an average weight loss of 27 lbs across its programme.
Twin’s higher absolute weight loss figure likely reflects a broader, more recent participant population (including higher-BMI individuals) and a longer average programme duration in its dataset.
Medication Reduction
Virta Health: 94% of participants reduced or eliminated at least one diabetes medication. 60% eliminated insulin entirely by year one.
Twin Health: 85% of participants on GLP-1 medications were able to eliminate them. 46% eliminated insulin.
Virta’s insulin elimination rate (60%) is notably higher than Twin’s (46%), possibly reflecting the strong insulin-sensitising effect of a very-low-carbohydrate diet. Twin’s GLP-1 elimination rate (85%) is a newer headline reflecting its more recent population.
How Each Programme Works Day-to-Day
Virta Health: Daily Life in the Programme
A typical Virta member starts by completing an intake screening and receiving a starter kit: a ketone meter, a blood glucose monitor, and app access. From day one, the goal is to achieve and maintain nutritional ketosis through carbohydrate restriction.
Daily life involves logging meals, checking ketone levels, and completing a brief daily app check-in with your health coach. Your Virta physician monitors your labs and biometrics remotely and adjusts medications proactively — typically reducing insulin within days to weeks as blood sugar normalises.
The programme runs Monday through Friday. If you experience side effects or need medical guidance over a weekend, you may need to seek care elsewhere. This is a documented limitation that appears regularly in patient reviews.
Members who have used Virta voluntarily consistently rate the coaching quality highly (4.5 stars on the App Store). The discipline required — strict carbohydrate restriction in a world full of carbohydrates — is the programme’s most significant practical challenge.
Twin Health: Daily Life in the Programme
A Twin Health member starts by receiving a sensor kit: typically a continuous glucose monitor, a wearable fitness tracker, a smart scale, and a blood pressure monitor. These devices feed real-time data into the AI Digital Twin model.
The app provides personalised daily guidance — specific food recommendations, activity targets, sleep coaching, and stress management tips — based on what the sensors reveal about your individual metabolic response. Twin’s approach does not require strict ketosis; it adapts to your unique physiology.
You also have access to a clinical care team for support, medication adjustments, and lab interpretation. Twin’s programme includes physician oversight for medication management, similar to Virta.
The precision-personalised approach means Twin’s recommendations are tailored specifically to you, which can feel less prescriptive and more sustainable for people who struggle with rigid dietary protocols.
Cost and Access
Virta Health
Virta is available primarily through employer health plans, where it is often fully covered. A direct-pay option exists, though pricing is not publicly listed and varies by eligibility.
For employer-enrolled members, cost is frequently zero or minimal — making it one of the more accessible options if your employer partners with Virta.
Twin Health
Twin Health operates exclusively through employer and health plan partnerships. There is no direct-pay pathway for individual consumers. If your employer or health plan does not partner with Twin, the programme is not accessible to you.
Twin’s fees-at-risk model — where the company ties its compensation to health outcomes — has made it attractive to self-insured employers seeking accountability.
What to Ask Your Benefits Administrator
If you’re trying to determine which programme your employer offers:
- Check your benefits portal under “diabetes management” or “chronic condition programmes”
- Call your health plan and ask specifically about Virta Health and Twin Health
- If your employer offers only one, that may be your only subsidised option

| App Store rating | 4.5 stars | Not widely reviewed publicly |
Who Should Choose Virta Health?
Virta is likely the better fit if you:
- Are genuinely motivated to follow a ketogenic diet long-term. The programme’s outcomes depend on adherence to carbohydrate restriction. If you’re intrinsically motivated (not employer-coerced), the research supports excellent outcomes.
- Want to eliminate insulin. Virta’s 60% insulin elimination rate at one year is among the highest published for any digital health programme.
- Prefer a single, proven protocol. Virta’s ketogenic approach is backed by over a decade of peer-reviewed research and more published follow-up data than any comparable programme.
- Have access through your employer (fully covered). If cost is zero and you’re willing to commit, Virta’s risk-reward profile is strong.
- Are interested in GLP-1 medications alongside lifestyle change. Virta’s 2024 expansion means you can access semaglutide or tirzepatide within the programme if eligible.
Caution: Virta’s clinical research was conducted with voluntary, motivated participants.
If you are being enrolled through an employer mandate — where non-participation means higher insurance premiums — be aware that the evidence base was built with a different population. The negative reviews on Trustpilot (2.5/5) and the BBB D− rating disproportionately reflect involuntary participants. If you feel coerced into the programme, your outcomes are likely to be worse than the trial data suggests. Read our deeper look at Virta Health reviews from real patients for the full picture.
Who Should Choose Twin Health?
Twin Health is likely the better fit if you:
- Cannot or do not want to follow a strict ketogenic diet. Twin’s personalised approach adapts to your metabolism without imposing a single dietary protocol.
- Want the most current published clinical evidence. Twin’s 2025 Cleveland Clinic study in NEJM Catalyst is the most recent large-scale RCT in this space, reporting 71% A1C remission.
- Value technology-driven personalisation. The AI Digital Twin model tracks your real-time metabolic response in a way no purely dietary programme can match.
- Have obesity or prediabetes alongside Type 2 diabetes. Twin’s programme explicitly covers prediabetes prevention, which Virta focuses on less.
- Your employer or health plan offers Twin. Since there is no direct-pay option, employer/plan coverage is the only pathway.
Are There Alternatives Worth Considering?
Both programmes are strong options — but neither may be right for every person. If you’re exploring your full range of options for Type 2 diabetes reversal:
- Intensive lifestyle programmes (CDC-recognised): The CDC’s National Diabetes Prevention Programme covers prediabetes and early T2D with a structured curriculum. Available through many employers and YMCAs at lower or no cost.
- Level2 (for UnitedHealthcare members): Level2 is a CGM-guided lifestyle programme available through select UHC health plans, using an ADA-based approach rather than strict ketosis. See our Virta Health vs Level2 comparison for a full breakdown of how it compares on approach, devices and clinical evidence.
- Primary care with a registered dietitian: For motivated patients, supervised dietary change with a knowledgeable dietitian and endocrinologist can achieve results comparable to the programmes above — without the app structure.
- GLP-1 medications alone: Semaglutide and tirzepatide have now demonstrated remission rates of their own in trials. For some patients, medication management without a structured lifestyle programme may be the more sustainable path.

The Bottom Line
Both Virta Health and Twin Health are clinically credible programmes with peer-reviewed research supporting their outcomes. Neither is a scam, and neither overpromises — the evidence behind both is real.
Virta is the right choice if you are willing to commit to a ketogenic dietary approach, want the longest follow-up data in the space, and need strong insulin elimination. Its 12+ years of published research and 4.5-star App Store rating from voluntary users speak to genuine efficacy for motivated participants.
Twin Health is the right choice if you want a precision-personalised approach that doesn’t require strict ketosis, value the most recent clinical evidence (NEJM Catalyst, 2025), and are enrolled through an employer or health plan that offers it. Its 71% A1C remission rate and -27 lb average weight loss are compelling headline figures.
The one factor that matters more than either programme’s clinical data: your own motivation. Both programmes produce their best outcomes in participants who choose to engage voluntarily. If you’re being enrolled through an employer mandate, ask yourself honestly whether you’re willing to commit — because the research supporting these numbers was built with participants who were.
Frequently Asked Questions
Which programme has better clinical evidence — Virta or Twin? Both have strong peer-reviewed evidence. Virta has more published studies and longer follow-up data (5+ years). Twin has more recent large-scale RCT evidence including a 2025 Cleveland Clinic study in NEJM Catalyst. Both are credible; Twin’s headline remission rate (71%) is higher, but direct comparison is difficult due to different study designs.
Can I do both Virta and Twin Health at the same time? No. Both programmes require exclusive enrolment and involve physician-managed medication adjustments — participating in both simultaneously would be medically inappropriate.
Does Virta Health offer GLP-1 medications? Yes, since 2024. Eligible Virta members can access semaglutide (Ozempic, Wegovy) or tirzepatide (Mounjaro, Zepbound) through Virta’s physicians as part of an expanded GLP-1 management pathway alongside the traditional ketogenic programme.
Is Twin Health only available through employers? Yes. As of 2026, Twin Health has no direct-pay option for individual consumers. The programme is available exclusively through employer health plans and health plan partnerships.
What happens if I stop either programme? Both programmes produce outcomes that depend on continued lifestyle engagement. If you stop following the dietary guidance or discontinue programme support, blood sugar and weight are likely to return toward baseline over time — particularly for Virta, where outcomes depend on maintained nutritional ketosis. The goal of both programmes is to establish durable habits, but metabolic improvements from any lifestyle intervention are typically not permanent without ongoing commitment.
Which programme is better for weight loss? Twin Health reports a higher average absolute weight loss (27 lbs) compared to Virta’s ~12% of body weight. For a 200-lb person, Virta’s 12% translates to approximately 24 lbs — broadly similar. Both produce clinically meaningful weight loss for the average participant.
