Lifestyle prescriptions for obesity treatment in primary care: a narrative review
Ji-Hye Jung, YangIm Hur
Received September 15, 2025  Accepted October 14, 2025  Published online October 27, 2025  
DOI: https://doi.org/10.12771/emj.2025.00836    [Epub ahead of print]
Purpose
This review aims to synthesize the most up-to-date evidence on effective lifestyle prescriptions for managing patients with obesity in the primary care setting.
Methods
A comprehensive literature search was conducted through June 2025 using major domestic and international databases, including PubMed, Google Scholar, and RISS, as well as the websites of relevant academic societies. The search strategy employed keywords such as “obesity,” “primary care,” “lifestyle intervention,” “diet,” “exercise,” and “behavioral therapy” in both English and Korean.
Results
Effective obesity management should be grounded in the new paradigm of adiposity-based chronic disease, which focuses on preventing and treating the medical complications associated with excessive fat accumulation. The essential components of a successful lifestyle prescription comprise 3 pillars: diet, exercise, and behavioral therapy. An individualized dietary plan that achieves an energy deficit of 500–750 kcal is fundamental. Exercise prescriptions should recommend a combination of aerobic and resistance training, along with strategies to minimize sedentary time. In behavioral therapy, high-intensity behavioral counseling, the 6A model (ask, assess, advise, agree, assist, arrange), self-monitoring, and cognitive-behavioral therapy techniques have all demonstrated efficacy.
Conclusion
Primary care physicians are not only capable but also uniquely positioned to lead long-term, patient-centered obesity management. Their comprehensive and integrative perspective makes them one of the most efficient and scalable resources in addressing the obesity epidemic.

Lifestyle interventions for hypertension management in primary care: a narrative review
Byoungduck Han, Gyu Bae Lee, Jihyun Yoon, Yang-Hyun Kim
Received September 18, 2025  Accepted October 11, 2025  Published online October 20, 2025  
DOI: https://doi.org/10.12771/emj.2025.00850    [Epub ahead of print]
Hypertension is one of the leading chronic diseases globally and a major contributor to cardiovascular morbidity and mortality. Despite advances in pharmacological therapy, medication alone remains limited in achieving optimal control. This review synthesizes recent hypertension management guidelines, including those from the European Society of Cardiology (ESC, 2024), American Heart Association/American College of Cardiology (AHA/ACC, 2025), Taiwan Society of Cardiology/Hypertension Society (2022), and Korean Society of Hypertension (KSH, 2018). All guidelines consistently emphasize sodium restriction, weight reduction, regular exercise, moderation of alcohol intake, smoking cessation, and adoption of healthy dietary patterns such as the Dietary Approaches to Stop Hypertension, Mediterranean, or culturally adapted diets. The ESC 2024 guideline elevates lifestyle modification to Class I, Level A, specifying targets for sodium (<2 g/day) and potassium (≥3.5 g/day). The AHA/ACC 2025 guideline provides quantitative estimates, reporting approximately 1/1 mm Hg blood pressure reduction per kilogram of weight loss, and incorporates newer strategies such as glucagon-like peptide-1 receptor agonists and bariatric surgery when lifestyle measures alone are insufficient. Taiwan’s 2022 guideline frames recommendations under the S-ABCDE (sodium restriction, alcohol limitation, body weight reduction, cigarette cessation, diet adaptation, exercise adoption) mnemonic and uniquely includes genetic factors such as ALDH2 polymorphisms. The KSH 2018 guideline emphasizes salt restriction (<6 g/day), maintaining a body mass index <25 kg/m2, and adherence to traditional Korean diets. Lifestyle modification remains the cornerstone of hypertension prevention and management, particularly in primary care. Future directions should focus on integrating these approaches with pharmacotherapy, digital health strategies, and personalized prescriptions.

Nutritional management for breast cancer patients
Minjeong Kim, Minkyoung Lee, Jisun Sa
Ewha Med J 2025;48(1):e11.   Published online January 31, 2025
DOI: https://doi.org/10.12771/emj.2025.e11

Breast cancer is a complex disease influenced by environmental, genetic, dietary, and hormonal factors. This underscores the importance of postoperative nutritional management in supporting recovery, minimizing complications, and enhancing long-term outcomes. This review synthesizes clinical guidelines, expert recommendations, and observational studies to provide a comprehensive overview of dietary interventions for breast cancer patients following surgery. Post-surgical nutritional care is centered around three primary objectives: supporting wound healing through high-quality protein intake, maintaining optimal nutritional status to prevent malnutrition, and promoting healthy lifestyle habits to reduce the risk of recurrence. To achieve these objectives, postoperative dietary strategies focus on several key components: ensuring adequate hydration for metabolic processes and tissue repair, consuming a balanced diet rich in fresh vegetables and fruits to mitigate oxidative stress, incorporating whole grains to support overall healing, and maintaining sufficient intake of high-quality protein from sources such as fish, meat, and dairy products to aid tissue repair and immune system recovery. Patients are also advised to avoid alcohol, limit saturated fats, and reduce intake of salty, sugary, and smoked foods to minimize inflammation. As research progresses, the implementation of personalized dietary plans remains essential for optimizing recovery outcomes in breast cancer patients.

Trends in Prevalence and the Differentials of Unhealthy Dietary Habits by Maternal Education Level among Korean Adolescents
Yunseo Chung, Kyunghee Jung-Choi, Bo Young Kim, Kyoung Ae Kong
Ewha Med J 2021;44(4):133-143.   Published online October 31, 2021
DOI: https://doi.org/10.12771/emj.2021.44.4.133
Objectives

This study aimed to investigate the prevalence of unhealthy dietary habits by maternal educational level and how the effect of maternal education changed between 2009 and 2019.

Methods

Using data from the Korea Youth Risk Behavior Survey conducted between 2009 and 2019, we assessed the prevalence of each unhealthy dietary habit (insufficient consumption of milk and fruit/vegetable, breakfast-skipping, and frequent consumption of fast food, soft drinks, and instant noodles) and the prevalence difference between maternal middle/high school and college graduate groups in four periods. The models included maternal educational level, four periods and the interaction between them, sex, and grade. In addition, we estimated the ORs of unhealthy dietary habits between the two maternal educational groups at each period.

Results

Throughout the study period, unhealthy dietary habits were consistently more prevalent among mothers with lower education levels. Between 2009–2010 and 2017–2019, the prevalence of unhealthy dietary habits increased, with a particular increase in that of frequent consumption of fast food and soft drink. The prevalence differentials between the middle school and college graduate group decreased or did not differ, while those between the high school and college graduate groups increased over time. A similar trend was observed in the relative scale.

Conclusion

Considering the increase in the prevalence of unhealthy dietary habits and the prevalence differentials by maternal educational level, targeted efforts are needed not only for all adolescents and their parents but also for those with low socioeconomic status to improve the dietary habits of adolescents.

Vegetable Diet in Cancer Prevention
Bo-Young Oh, Kyoung Tae Noh, Ryung-Ah Lee, Kwang Ho Kim
Ewha Med J 2012;35(1):11-15.   Published online March 31, 2012
DOI: https://doi.org/10.12771/emj.2012.35.1.11

Cancer prevention by vegetable diet has received considerable attention in recent years. In the past these attributes of vegetables were based more on beliefs than on scientific evidences. But over the past few decades many studies have been performed about that. Cancer preventive components of many vegetables have been studied in experimental carcinogenesis models. These studies have reported on these components influence carcinogenesis during initiation and promotion phases of cancer development. Also, epidemiological studies and clinical trials have reported cancer preventive effects of vegetables. However, there is no comprehensive summary of cancer preventive effects with the types of vegetables. In this review, we classified the vegetables and described the mechanism of action of active components of vegetables, experimental studies, and clinical trials. Results revealed a negative correlation between consumption of vegetables and cancer risk. But we can't still conclude the effects of vegetables yet, so further studies would be necessary for final conclusion.
