Effectiveness of Low-Calorie MIND-HK Diet and Very Low-Calorie Diet on Glycemic Control and Cardiovascular Outcomes in Adults With Type 2 Diabetes: A 12-Week Randomized Controlled Trial
Přehled studie

Podmínky
Detailní popis
This study addresses the critical clinical need to optimize dietary interventions for Chinese adults managing Type 2 Diabetes Mellitus (T2DM). While calorie restriction is widely known to aid in diabetes management, there is limited evidence comparing the distinct efficacy and physiological safety profiles of a standard low-calorie diet versus an intensive, very low-calorie approach when adapted to local dietary preferences. By evaluating the tailored MIND-HK diet, this trial aims to establish an effective, practical framework for improving long-term glycemic control and reducing cardiovascular risks.
To achieve robust and reliable results, the study uses a rigorous 12-week, parallel-group Randomized Controlled Trial (RCT) design involving 180 participants divided equally into three arms. The structure combines intensive, professional in-person coaching from a registered nutritionist with continuous remote support via WhatsApp to maximize participant adherence and behavioral retention. Furthermore, the integration of the Bluetooth-connected KetoMetrics Breath Ketone System provides a critical safety buffer, allowing real-time tracking of calorie intake and early detection of ketosis to prevent complications like diabetic ketoacidosis (DKA). By standardizing the contact time across all arms-including an attention control group receiving infectious disease health education-the trial minimizes bias and ensures that any observed improvements in HbA1c, fasting glucose, lipid profiles, and blood pressure are directly attributable to the nutritional interventions.

Experimentální: Low-calorie MIND-HK diet
Low-calorie MIND-HK diet is based on the MIND diet originally developed by Morris and colleagues in 2015 (1, 2) and adapted from the Arjmand group's 3-month MIND diet intervention (5).
The Low-calorie MIND-HK diet intervention will be a 12-week nutrition program consisting of four in-person nutrition counselling sessions (one session per week, 60 minutes per session and 30 minutes question and answer session) in an activity room at each participating community centre.
All sessions will be conducted by a registered nutritionist.
In the nutrition sessions, the participants will learn to modify their diet to meet the low-calorie MIND-HK diet guidelines.
|
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.

Experimentální: Very Low-calorie MIND-HK diet
Very Low-calorie MIND-HK diet is based on the MIND diet originally developed by Morris and colleagues in 2015 (1, 2) and adapted from the Arjmand group's 3-month MIND diet intervention (5).
The very Low-calorie MIND-HK diet intervention will be a 12-week nutrition programme consisting of four in-person nutrition counselling sessions (one session per week, 60 minutes per session and 30 minutes question and answer session) in an activity room at each participating community centre.
All intervention sessions will be conducted by a registered nutritionist.
In the nutrition sessions, the participants will learn to modify their diet to meet the low-calorie diet guidelines.
As a reference, a 7-day sample menu that meets the required number of servings per day will be provided.
To maintain consistency, one nutritionist and one research assistant, will administer the intervention.

Jiný: 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) (6).
