Abstract

Objective: Obesity is a significant medical issue that goes beyond simple weight gain, serving as a key factor in the development of various metabolic diseases. Generally, a body mass index (BMI) of 25 or higher is considered overweight, and 30 or higher is considered obese. However, even individuals with a normal BMI may develop metabolic disorders due to abdominal obesity or ectopic fat accumulation. Dietary management and lifestyle modification are the primary interventions for obesity treatment, although pharmacological therapy is sometimes combined. Recently, GLP-1 receptor agonists have received attention for obesity treatment, but gastrointestinal adverse effects such as nausea, vomiting, and diarrhea are common. Case Report: This case study involved a Korean man in his 40s who had maintained a muscular overweight status for the past 15 years and complained of abdominal obesity and knee pain. Ortho-Cellular Nutrition Therapy (OCNT) prescribing plant-based protein, anthocyanins, green coffee bean extract, and Garcinia cambogia was implemented. As a result, the patient’s body weight decreased by 1.5 kg, and body fat mass decreased by 2.2 kg. Conclusion: The patient experienced reductions in both body weight and body fat through OCNT; however, as this observation was limited to a single case over a short period, further research is needed to determine whether the same effects are consistent in patients with different body types. Nevertheless, the results are meaningful in demonstrating that OCNT can contribute to body fat reduction even while maintaining existing lifestyle habits.
