What researchers measure

Primary outcomes

  1. Remission

    The diabetes remission rate at Week 12 will be compared between the intervention and control groups relative to baseline. Remission of type 2 diabetes is defined, in accordance with the 2021 consensus report by American and European experts (Diabetes Care 2021;44:2438-44), as an HbA1c level of less than 6.5% at the end of the 12-week intervention, following discontinuation of all glucose-lowering medications at baseline.

    Time frame: From enrollment to the end of treatment at 12 weeks

Secondary outcomes

  1. Body weight

    Body weight will be measured in kilograms (kg) using a calibrated scale. Changes from baseline will be evaluated.

    Time frame: Assessments will be performed at baseline and week 12. For participants who consent to the extension of the study period, additional assessments will be conducted at weeks 18 and 24.
