A clinic-based low-carb program put 93% of people with prediabetes into remission and was tied to a halving of cardiovascular-death risk over 20 years, shifting the keto debate from short-term glucose control to long-range heart outcomes. The big question is not just whether insulin resistance improves, but whether early remission changes what happens decades later.
The new analysis in The Lancet Diabetes & Endocrinology is titled Prediabetes remission and cardiovascular morbidity and mortality: post-hoc analyses from the Diabetes Prevention Program Outcome study and the DaQing Diabetes Prevention Outcome study. PubMed lists it under PMID 41397402. It pulled together follow-up from the Diabetes Prevention Program Outcome Study and the Da Qing Diabetes Prevention Outcome Study, and its central message was blunt: when blood glucose returned to normal, long-term cardiovascular morbidity and mortality were lower. The Whitehall II cohort study, published in 2019, had already pointed in the same direction by examining reversion from prediabetes to normoglycaemia and later cardiovascular disease and mortality, while the Da Qing Diabetes Prevention Outcome Study reported 30-year results after lifestyle intervention for impaired glucose tolerance.
The clinic result now sitting on top of that literature is the eye-catcher for the keto crowd. A low-carb diet achieved 93% remission of prediabetes in that setting, and the same body of work linked the approach to a 50% lower risk of cardiovascular death over 20 years. That is a much bigger claim than better fasting glucose or a nicer A1c. It suggests that getting out of the prediabetes range may be part of a cardiovascular prevention strategy, not just a diabetes-avoidance tactic.
King’s College London made that point plainly in a Dec. 15, 2025 release, saying: “lowering blood sugar levels halves the likelihood of serious heart problems in people with prediabetes.” That framing fits the broader remission literature, which keeps circling back to the same thing: normalizing glucose may matter for heart disease, not only for diabetes.
The caveat is the setting. The 93% remission figure came from a clinic-based program, not a casual at-home reset, so the result says as much about the structure around the diet as the carb count itself. For anyone following keto as a health tool, that is the real stakes question now: whether early low-carb intervention can do more than move numbers on a meter and actually bend cardiovascular risk over the long haul.
