From the Journal of the Academy of Nutrition and Dietetics:
Based on the current evidence, a specific dietary intervention for diabetes prevention in women with prior GDM [gestational diabetes mellitus] can therefore not be recommended. Previous systematic reviews have also consistently concluded that evidence for an effect of combined diet and physical activity interventions is inconclusive, with the exception of strong evidence from the Diabetes Prevention Program. Findings from that intensive intervention that focused on diet and physical activity to achieve and maintain weight loss of at least 7% of initial body weight showed >50% reduction in the risk of developing T2DM in women at high risk of T2DM including women with previous GDM; however, this personalised lifestyle intervention is unlikely to be feasible for implementation in routine care. As a limited number of studies have examined diet-alone and physical activity-alone interventions, it remains unclear which diabetes prevention approach would be most effective for women with a GDM history.

If it were me? I’d lose the excess weight with a reasonable diet and exercise regularly.
