The Effect of a Nutritionally Balanced Low Calorie Diet Based on Traditional Indonesian Foods on Obese People's Metabolic Biomarkers

The research was carried out at RSUP dr. M. Djamil Padang. The research ethics commission of Andalas University's Faculty of Medicine granted the study an ethical permit. Health workers with a BMI of more than 25 kg/m2 became the study population, and officers who agreed to participate in the study after filling out the informed consent form were included in the study. There were 91 people in the study. The study lasted eight weeks (56 days). A week before the study, participants were interviewed about their daily intake using 24-hour food recall, and anthropometric measurements were taken using calibrated tools and performed by trained officers.

Subjects underwent a one-week pre-treatment period (baseline period, beginning on D-day 6 and ending on D-day 0), during which they were asked not to take any supplements. All participants had their anthropometric measurement, blood pressure, body fat percentage, fasting blood sugar levels, and lipid profile checked on day 0 and day 57.

The Nutrisurvey 2005 application was used to process the daily intake of participants obtained from a 24-hour food recall interview. Dietary interventions were given with a calorie deficit of 500-600 kcal from the participants' usual daily intake. A Minangkabau food menu is provided as part of the diet. Participants are given a list of daily menus, which include breakfast, lunch, and dinner. Researchers provided lunch for study participants, while breakfast and dinner were prepared independently by participants using the dietary guidelines and menus provided. Participants kept a food diary, which was collected and evaluated twice a week. The research team also controls and motivates all participants via Whatsapp groups. The study's findings were analyzed using the SPSS software.
