What this study is about
The goal of this clinical trial is to evaluate whether a genetic score (Gens-HiPro) acts as a response modifier for weight loss, body composition changes, and biochemical parameters in obese adults undergoing a low-energy high-protein diet intervention. The main questions it aims to answer is: Does the genetic score (Gens-HiPro) modify responses to changes in weight, body composition, and biochemical parameters following a 12-week low-energy high-protein diet? Participants will: * Undergo initial screening to determine eligibility based on inclusion and exclusion criteria * Complete baseline data measurement, including demographic data, anthropometric measurements (weight, BMI, body composition), biochemical blood analysis (total cholesterol, triglycerides, HDL, LDL, CRP), dietary assessment. * Attend a small-group educational session on general guidelines, portion control, plate model ("Isi Piringku"), and food weighing techniques for a low-energy high-protein diet. * Receive a 60-90 minute nutritional counseling session led by a dietitian at the start of intervention * Follow the prescribed 12-week low-energy high-protein diet, supported by an active messaging channel on weekdays for daily dietary consultations * Participate in at least three in-person monitoring and evaluation visits scheduled every 3-4 weeks (at weeks 4, 8, and 12 or weeks 4, 7, 10 and 12) * Complete post-intervention evaluations at the end of week 12, repeating all baseline anthropometric, biochemical, and dietary assessments.

Treatments and study arms
Low-Energy High-Protein Diet
This intervention consists of a 12-week low-energy high-protein diet program delivered through structured behavioral and nutritional counseling. Nutrition care process: individual nutritional counseling, one-on-one counseling session conducted by a registered dietitian. The dietary regimen is prescribed with an energy deficit of 500-750 kcal/day, ensuring a minimum daily energy intake of 1.200 kcal/day for women and 1.500 kcal/day for men. Macronutrient distribution is targeted at 1.2-1.6 g/kg adjusted body weight for protein, 20-30% of total energy for fat, and 45-55% of total energy for carbohydrates. Genetic profiling using the Gens-HiPro score is conducted to evaluate its role as a modifier of outcome responses in weight loss, body composition, and biochemical parameters.
Primary outcomes
Body weight refers to the total body mass of the subject, measured using a weighing scale in kilograms (kg). The change in body weight is calculated as the difference between the body weight value at the baseline of the intervention (Week 0) and the end of the intervention (Week 12). (Scale: Ratio)
