Clinical Trial Summary

This is an exploratory controlled before-after study, which involves 112 participants, of whom 28 are with normal weight and 84 are overweight or obese. Twelve weeks of personalized nutritional and lifestyle weight reduction intervention will be conducted in the overweight or obese participants. The objectives of this study are to 1) characterize metabolic homeostasis under resting and exercise conditions, 2) to explore the potential impact factors on metabolic homeostasis, and 3) to investigate whether personalized nutritional and lifestyle weight reduction intervention can improve metabolic health in overweight or obese Chinese individuals and how is it comparable to healthy normal weight Chinese population.


Description:

The objectives of this study are to 1) characterize metabolic homeostasis under resting and exercise conditions, 2) to explore the potential impact factors on metabolic homeostasis, and 3) to investigate whether personalized nutritional and lifestyle weight reduction intervention can improve metabolic health in overweight or obese Chinese individuals and how is it comparable to healthy normal weight Chinese population. In this study, 84 overweight or obese participants (BMI ≥ 24 kg/m2) and 28 normal weight participants (18.5 ≤ BMI<24 kg/m2) will be recruited and receive 12-week personalized weight reduction or weight maintenance nutritional and lifestyle interventions. Before and after the 12-week interventions, metabolic homeostasis will be used to characterize metabolic health and to be determined using comprehensive measurements of dynamic changes in postprandial metabolic responses (including energy metabolism, multiple clinical biomarkers, metabolomic signatures, gut microbiota, genetic signatures etc.) after the standardized mixed-nutrient dietary challenges (75 g glucose, 60 g fat and 20 g protein) in whole room indirect calorimeter under both resting and exercise conditions. In addition, data from dietary intake, anthropometric measurements, body composition, psychosocial measures, behavior questionnaires and 14-day continuous glucose monitoring will also be collected to characterize metabolic homeostasis. During the interventions, participants will receive personalized dietary advice, behavior guidance and nutritional and lifestyle education by dietitian and physicians. APP-connected wearable devices will be utilized to monitor their dietary intakes, physical activities and sleep conditions, and an application-connected scale will be used to monitor their weight changes during interventions. The study's protocol has been approved by the Ethics Committee of Sir Run Run Shaw Hospital.

Outcome

Type Measure Description Time frame Safety issue
Primary Change from Baseline in Metabolic Homeostasis Score at 12 Weeks A metabolic homeostasis score is a composite score that includes aggregated changes in blood biomarkers (metabolites or biomarkers or index involved in carbohydrates metabolism such as glucose, C-peptide, Matsuda index etc.; metabolites or biomarkers involved in lipid metabolism such as high-density lipoprotein cholesterol, total cholesterol, triglyceride etc.; metabolites or biomarkers involved in protein/vitamin metabolism such as creatinine; inflammatory or cytokines such as interleukin-6 etc.; hormones; anthropometric measures etc.).
The metabolic homeostasis score is a composite score, that is calculated by the average of the scores of above-mentioned features using a certain computational algorithm. The larger the metabolic homeostasis score is, the worse the homeostatic resilience of the person, and vice versa.
