Summary

The objective of this project is to assess the effectiveness of a low-calorie and very low-calorie Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND-HK) diet in improving glycemic control and cardiovascular outcomes in adults with T2DM. A total of 180 participants aged 40 to 70, diagnosed with T2DM, will be recruited and randomized into three groups: intervention 1 following the low-calorie MIND-HK diet, intervention 2 following the very low-calorie diet, and an attention control group. The two intervention groups will attend four in-person nutrition counseling sessions (one per week, 60 minutes per session, followed by a 30-minute Q\&A) at a community centre and will use KetoMetrics Breath Ketone System and dietary mobile app, to track diet and monitor daily ketone levels for early signs of ketosis that may lead to diabetic ketoacidosis (DKA). The attention control group will receive an equal amount of attention through four in-person infectious disease counseling sessions. The primary outcome will be HbA1c levels. Secondary outcomes include fasting blood glucose, lipid profile, blood pressure, body mass index, waist circumference, breath ketone, scores from the Summary Diabetes Self-Care Activities (SDSCA) Questionnaire, and MIND diet scores. This study will contribute to the growing body of evidence on dietary interventions for managing T2DM in adults.

Interventions

BEHAVIORAL

Low-calorie MIND-HK diet

This 12-week community-based lifestyle intervention is designed to help participants modify their daily intake to meet low-calorie MIND-HK dietary guidelines. The program includes four weekly education sessions (60-minute lesson and 30-minute Q\&A) covering portion control and food groups, alongside continuous monitoring of dietary logs to track compliance and support self-management throughout the study period.

BEHAVIORAL

Very Low-calorie MIND-HK diet

This 12-week community-based lifestyle intervention is designed to help participants modify their daily intake to meet very low-calorie MIND-HK dietary guidelines. Administered by a consistent team of one nutritionist and one research assistant to ensure program fidelity, the intervention includes four weekly sessions (60-minute lesson and 30-minute Q\&A) covering calorie-reduction strategies, alongside the distribution of structured sample menus and continuous tracking to support dietary compliance.

OTHER

Control group

An attention control group will receive the same amount of attention in four in-person infectious disease counselling sessions (one session per week, 60 minutes per session, and a 30- minute question and answer session).
