An intensive diet-and-exercise program produced type 2 diabetes remission in 54% of younger adults after 24 weeks, versus 4% with usual care. “Remission” meant HbA1c below 6.5% without glucose-lowering medication for at least 12 weeks—not a permanent cure.
What changed
The RESET for Remission trial randomized 96 adults aged 18–45 with obesity and type 2 diabetes diagnosed within six years. The intervention combined an 800–900-kcal medically supervised diet with aerobic and resistance exercise; usual care served as the control. At 24 weeks, 27 of 50 intervention participants and 2 of 46 controls met the remission definition. Adjusted weight loss was 7.5 kg greater, including 6.6 kg more fat loss.
How strong is the evidence?
This was a multicenter, randomized, open-label trial with blinded endpoint assessment. Randomization supports a causal effect of the complete program. However, it cannot separate the contributions of meal replacement, calorie restriction, supervised exercise, frequent support, and medication withdrawal.
What remains uncertain
The sample was small, follow-up lasted only 24 weeks, and participants were younger than 46 and not using insulin. Whether remission and muscle preservation persist after weight regain is unknown. Adverse events were more frequent with the intervention—mostly constipation, headache, dizziness, and fatigue—although no severe events were reported.
Why it matters
The result shows that early type 2 diabetes can sometimes enter remission under intensive supervision. It does not establish that people should copy the calorie target or stop diabetes or blood-pressure medicines on their own.
