Severe caloric restriction (Very Low Calorie Diet) can normalize beta-cell function and reverse Type 2 Diabetes, though it is not sustainable long-term for most patients.
A 600 kcal/day diet can reverse T2DM by restoring beta-cell function, but it is not sustainable. This approach is generally reserved for medical supervision or bariatric surgery contexts rather than self-managed lifestyle changes.
ModerateSupportsMEDIUM confidence
At more extreme levels, dietary energy restriction with a very low calorie diet (600 k/cal day) for 8 weeks normalised beta-cell function and resulted in a reversal of T2DM (37).
Why this rating
Based on specific trials (Ref 37) cited, but noted as having limited long-term follow-up data.

More from this paper
- Intensive lifestyle interventions resulting in significant weight loss (approx. 8.6% at 1 year) improve glycaemic control, reduce cardiovascular risk factors, and induce remission of type 2 diabetes, although they have not been shown to reduce the rate of major cardiovascular events compared to standard care.Good
- Weight loss improves quality of life, mobility, physical function, and remission of obstructive sleep apnoea in T2DM patients, independent of cardiovascular event rates.Good
