TLDW - With medical supervision T2D can be reversible using a ketogenic nutritional therapy.
Type 2 diabetes doesn’t just need to be managed; it can be reversed.
For years, endocrinologist Dr. Mariela Glandt followed the conventional playbook: carefully adjusting medications, prescribing the latest drugs, and urging patients to eat whole grains and lean proteins. Yet her patients kept getting sicker, medications piled up, and their diabetes was treated as an inevitable, “progressive” disease.
Then came a turning point.
Through her research, Dr. Glandt came across scientific evidence that showed we could address insulin resistance head-on: by removing excess carbohydrates, patients could actually reverse their condition. No longer bound to insulin injections and endless prescriptions, they could reclaim their health.

Clinical shift
- Years of diabetes care focused on glucose targets, medication adjustment, and newer drugs while patients remained under escalating medication burden.
- Standard advice about the gym, whole grains, lean meats, fruits, and vegetables did not get patients off medications.
- Type 2 diabetes can be reversed when insulin resistance is the root cause. Mechanism and diet
- Type 2 diabetes is the body reaching a limit with sugar and carbohydrate load.
- Carbohydrate removal removes the offending agent and diabetes fades.
- Carbohydrates are not essential nutrients because the liver makes the glucose the body needs through gluconeogenesis.
- A well-formulated low-carbohydrate diet is rich in natural proteins and fats.
- Blood sugar goes down, normalizes, the body heals, and medications are peeled away. Patient impact
- The first patient on the protocol lost 60 pounds in 6 months, dropped A1C from 10 to 5.4, and stopped every medication, including insulin.
- The deeper change is fear lifting, hope returning, and health no longer feeling like a personal failure.
- Seeing that change makes return to the earlier approach impossible.
Scaling and evidence
- Ketogenic diet use or therapeutic carbohydrate restriction reached about 4,000 patients before Ona Health was founded to scale the work, especially for Medicaid patients.
- This approach reverses diabetes at a fractional cost of traditional therapies.
- The country carries tens of millions of diabetes and prediabetes cases plus downstream costs from amputations, heart attacks, dialysis, depression, and the rest of the burden of type 2 diabetes.
- Ketogenic diets are therapeutic, medicinal, and curative.
- The evidence is strong enough that this approach would have received FDA approval long ago if it had been a drug.
- ADA consensus language puts carbohydrate reduction at the top of the evidence base, and Tracey Brown reversed her own diabetes with a ketogenic diet.
Policy and access
- A humane and affordable option already exists that targets root cause, gives energy, lowers sugar cravings, and creates lasting satiety.
- Federal and Medicaid pilots can spread this model across the country.
- Food as medicine can expand access to healthy food and reverse chronic disease at scale.
- The evidence is already in hand, the tools already exist, and the time is now.
