According to a study, adults who are overweight or obese and have type 2 diabetes or prediabetes are at a higher risk of developing severe health issues. Experts disagree on the best dietary regimens and supportive measures to suggest, though.

The study was published in the journal 'The Annals of Family Medicine'. In these findings, researchers used a 2 x 2 diet-by-support factorial design to randomise 94 adults with the aforementioned conditions, contrasting a very low-carbohydrate (VLC) or ketogenic diet with a Dietary Approaches to Stop Hypertension (DASH) diet. They also determined the outcomes of interventions that included and excluded additional support practices like mindful eating, effective emotion regulation, social support, and cooking instruction.
