This study aims to evaluate the effectiveness of the Lifestyle Intervention for Gentle, Healthy Transformation and Enhanced Weight Reduction-metabolic syndrome (LIGHTER-MetS) program on dietary self-regulation and cardiovascular risk among individuals with metabolic syndrome (MetS). The LIGHTER-MetS program, a community-based, grassroots-led initiative, integrates health coaching with the eTRIP© app to promote sustainable lifestyle changes focusing on diet, exercise, and emotion regulation.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| LIGHTER-MetS | Experimental | The LIGHTER-MetS program includes community-based health coaching by the PI or a trained healthcare professional (e.g. nurse, physiotherapist etc.) at baseline visit and for 3 months following the baseline visit. Throughout the first 3 months, participants will also use the eTRIP© app to log meals, monitor physical activity, and receive personalized feedback. During the 3-month intervention period, there will be one-to-one slots for the health coach to follow up on participants' health plan. |
|
| Control | No Intervention | Participants will receive personalised health plans provided as part of usual care when they see a family physician. As part of the HealthierSG initiative, health plans are typically formulated to target early disease prevention and chronic condition management through history taking, physical examination, appropriate diagnostic testing, treatment, referrals and lifestyle modification goals and activity planning. |

| LIGHTER-MetS | Behavioral | The LIGHTER-MetS program includes community-based health coaching by the PI or a trained healthcare professional (e.g. nurse, physiotherapist etc.) at baseline visit and for 3 months following the baseline visit. Throughout the first 3 months, participants will also use the eTRIP© app to log meals, monitor physical activity, and receive personalized feedback. During the 3-month intervention period, there will be one-to-one slots for the health coach to follow up on participants' health plan. |
| Measure | Description | Time Frame |
|---|---|---|
| Self regulation of Eating Behaviour Questionnaire (SREBQ) | The Self-Regulation of Eating Behaviour Questionnaire (SREBQ) is a validated self-administered instrument used to assess individuals' self-regulation in relation to eating behavior. It evaluates the extent to which individuals monitor, control, and regulate their eating behaviors in everyday contexts. Higher scores indicate greater self-regulation of eating behavior. | At baseline, 3, 6, and 12 months. |
| Cardiovascular Risk | Cardiovascular risk will be assessed via the ASCVD-risk calculator and the Singapore-modified Framingham Risk Score 2023 (SG-FRS-2023). Higher scores indicate a greater estimated cardiovascular risk. | At baseline, 3, 6, and 12 months. |
| Measure | Description | Time Frame |
|---|---|---|
| Weight | At baseline, 3, 6, and 12 months. | |
| Waist Circumference | At baseline, 3, 6, and 12 months. | |
| Blood Pressure |

Both systolic and diastolic blood pressure will be assessed. |
| At baseline, 3, 6, and 12 months. |
| Three Factor Eating Questionnaire (TFEQ) | The Three-Factor Eating Questionnaire (TFEQ) is a validated self-administered instrument used to assess eating-related behaviors. It measures three domains: cognitive restraint of eating, uncontrolled eating, and emotional eating. Higher scores indicate greater levels of the respective eating behavior. | At baseline, 3, 6 and 12 month. |
| Consideration of Future Consequences Scale (CFCS-6) | The Consideration of Future Consequences Scale - 6 item (CFCS-6) is a validated self-administered questionnaire used to assess the extent to which individuals consider the potential future outcomes of their current behaviors. It evaluates the degree to which individuals weigh immediate versus future consequences when making decisions. Higher scores indicate greater consideration of future consequences. | At baseline, 3, 6 and 12 month. |
| Self-Report Behavioural Automaticity Index (SRBAI) | The Self-Report Behavioural Automaticity Index (SRBAI) is a validated self-administered questionnaire used to assess the automaticity of behavior. It evaluates the extent to which a behavior is performed automatically, with little conscious thought or deliberation. Higher scores indicate greater behavioral automaticity. | At baseline, 3, 6 and 12 month. |
| International Physical Activity Questionnaire Short-Form (IPAQ-SF) | The International Physical Activity Questionnaire - Short Form (IPAQ-SF) is a validated self-administered questionnaire used to assess self-reported physical activity levels. It captures the frequency and duration of walking, moderate-intensity activity, and vigorous-intensity activity performed over the past 7 days. | At baseline, 3, 6 and 12 month. |
| Generalized Anxiety Disorder 2-item (GAD-2) | The Generalized Anxiety Disorder - 2 item (GAD-2) is a validated self-administered screening questionnaire used to assess the frequency of core anxiety symptoms over the past two weeks. Higher scores indicate greater anxiety symptom severity. | At baseline, 3, 6 and 12 month. |
| Patient Health Questionnaire-2 (PHQ-2) | The Patient Health Questionnaire - 2 item (PHQ-2) is a validated self-administered screening questionnaire used to assess the frequency of depressive symptoms over the past two weeks. Higher scores indicate greater depressive symptom severity. | At baseline, 3, 6 and 12 month. |
| Perceived Stress Scale (PSS-10) | The Perceived Stress Scale - 10 item (PSS-10) is a validated self-administered questionnaire used to assess perceived stress levels over the past month. It measures the extent to which individuals perceive situations in their lives as stressful. Higher scores indicate greater perceived stress. | At baseline, 3, 6 and 12 month. |
| Euro Quality of life 5 Dimensions-5 Levels (EQ-5D-5L) | The EuroQol 5 Dimensions - 5 Levels (EQ-5D-5L) is a standardized self-administered instrument used to assess health-related quality of life. It measures five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, each with five response levels. | At baseline, 3, 6 and 12 month. |
| Big Five Inventory - 44 item (BFI-44) | The Big Five Inventory - 44 item (BFI-44) is a validated self-administered questionnaire used to assess personality traits across five domains: openness, conscientiousness, extraversion, agreeableness, and neuroticism. Higher scores indicate greater expression of the respective personality traits. | At baseline, 3, 6 and 12 month. |
| BMI | Measured using InBody 120. | At baseline, 3, 6 and 12 month. |
| Percentage Body Fat | Measured using InBody 120. | At baseline, 3, 6 and 12 month. |

| Fasting Blood Glucose (mmol/L) | Fasting blood glucose is a biochemical measure of blood glucose concentration after an overnight fast, measured using standard laboratory blood analysis. Higher values indicate poorer glycaemic control. | At baseline, 3, 6 and 12 month. |
| Glycated haemoglobin (HbA1c) (%) | Glycated haemoglobin (HbA1c) reflects average blood glucose levels over the preceding two to three months and is measured using standard laboratory blood analysis. Higher values indicate poorer long-term glycaemic control. | At baseline, 3, 6 and 12 month. |
| Triglycerides (mmol/L) | Triglycerides are a lipid biomarker measured using standard laboratory blood analysis to assess circulating triglyceride levels. Higher values indicate poorer lipid profiles and increased cardiometabolic risk. | At baseline, 3, 6 and 12 month |
| High-density lipoprotein cholesterol (HDL-C) (mmol/L) | High-density lipoprotein cholesterol (HDL-C) is a lipid biomarker measured using standard laboratory blood analysis to assess protective cholesterol levels.
