Energy balance

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.

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).
