Introduction: Obesity is a major public health concern linked to higher morbidity and mortality. Nutritional education programs play a crucial role in promoting healthy habits and improving clinical, biochemical, and body composition parameters.
Materials and Methods: An observational before-and-after study was conducted on patients with obesity who participated in a 5-session program at the Endocrinology and Nutrition Unit of HUPM (January 2022 - October 2024). Clinical, anthropometric, biochemical, and body composition parameters were analyzed.
Results: A total of 101 patients participated (63.4% women, mean age 47 years, BMI 41.9 kg/m2). Hypertension was present in 40.6%, dyslipidemia in 24.8%, type 2 diabetes in 17.9%, and prediabetes in 15.8%. Of these, 34.8% were treated with GLP-1 receptor agonists, showing greater but non-significant weight loss (8.9 ± 9.82 kg vs. 7.96 ± 5.44 kg). Baseline and final BIVA assessments were performed in 36 patients, with the following results: Patients with good adherence to the program lost more weight compared to those with poor adherence: A significant improvement in glycemic control was observed, as demonstrated in the biochemical parameters below:
| BIVA Parameters | Baseline (Mean ± SD) | Final (Mean ± SD) | p-value |
| Rz (Ohm) | 481 ± 67.9 | 498.9 ± 62.9 | < 0.001 |
| Xc (Ohm) | 46.4 ± 7.78 | 47.3 ± 6.75 | 0.207 |
| Pha (°) | 5.53 ± 0.68 | 5.46 ± 0.64 | 0.272 |
| TBW (L) | 42.7 ± 7.63 | 40.3 ± 7.19 | < 0.001 |
| FFM (Kg) | 57.4 ± 9.84 | 55.2 ± 9.23 | < 0.001 |
| FM (Kg) | 51.1 ± 17.4 | 46.3 ± 15.6 | < 0.001 |
| BCM | 29.4 ± 4.27 | 28.1 ± 4.12 | < 0.001 |
| ASMM (Kg) | 23.7 ± 4.65 | 22.1 ± 4.25 | < 0.001 |
| Program Adherence | Weight Loss (Kg, Mean ± SD) | Mean Difference | p-value |
| Poor (1-2 sessions) | 3.56 ± 2.89 | Intermediate - Poor = 1.32 | 0.652 |
| Intermediate (3-4 sessions) | 4.88 ± 4.95 | Good - Intermediate = 5.25 | 0.003 |
| Good (5 sessions) | 10.13 ± 7.42 | Good - Poor = 6.57 | < 0.001 |
| Biochemical Parameters | Baseline (Mean ± SD) | Final (Mean ± SD) | p-value |
| Glucose (mg/dl) | 100.11 ± 20.84 | 91.27 ± 15.35 | 0.005 |
| HbA1c (%) | 5.83 ± 0.81 | 5.59 ± 0.57 | 0.016 |
| Total Cholesterol (mg/dl) | 193.36 ± 45.57 | 179.93 ± 48.20 | 0.042 |
Conclusions: The nutritional education program improved anthropometric, biochemical, and body composition parameters. Participants who completed the program showed significant weight loss. No significant differences were found in weight loss between patients receiving GLP-1 treatment and those who did not. These results highlight the importance of nutritional intervention in managing obesity.
