Low-Energy Diet Plus Supervised Exercise Induces Remission in 54% of Early-Onset Type 2 Diabetes Cases

The intervention delivered an 800-900 kcal regimen (30% protein, 50% carbohydrate) using Optifast meal replacements for the first two weeks then one whole-food meal daily, alongside three weekly exercise sessions. Remission required HbA1c below 6.5% off all glucose-lowering drugs for at least 12 weeks. The diet-exercise arm lost 8.4 kg (7.5 kg adjusted difference), predominantly fat mass, while preserving lean tissue, contrasting with the 1.2 kg loss in controls. This approach extends the DiRECT trial's diet-only remission model to younger patients whose faster beta-cell decline makes early reversal more urgent. Structured exercise likely mitigated muscle loss common in caloric restriction, supporting sustained resting metabolism and insulin sensitivity beyond weight reduction alone. Early-onset diabetes accelerates microvascular and macrovascular complications compared with later onset; reversing it before age 45 could meaningfully alter lifetime risk trajectories. Yet the 24-week endpoint leaves durability unknown, and very-low-calorie adherence outside research centers remains challenging. Larger trials with 2-year follow-up and cardiovascular endpoints are required to confirm whether remission persists and translates to fewer events than standard management.
