Abstract:
Background: Obesity is frequently approached through outdated weight-centric metrics and late-stage disease markers, often overlooking early metabolic dysfunction and the physiologic drivers of appetite regulation. While pharmacologic therapies have expanded treatment options, many patients and clinicians lack a clear understanding of how macronutrient intake as well as eating patterns influences appetite-regulating hormones and how commonly available laboratory markers can identify metabolic risk well before the onset of diabetes.
Purpose: This presentation aims to demonstrate a practical, patient-centered framework for obesity care that integrates macronutrient physiology, early metabolic biomarkers, and exam-room education to improve patient understanding, engagement, and early intervention.
Approach: Drawing from primary care and obesity-focused clinical practice, this session reviews the differential effects of protein, carbohydrates, and dietary fat on key appetite-regulating hormones, including insulin, ghrelin, leptin, GLP-1, and peptide YY. The presentation further explores the interpretation of accessible laboratory marker; such as fasting insulin, HOMA-IR, and triglyceride-to-HDL ratio as early indicators of metabolic dysfunction, even when traditional laboratory values remain within “normal” ranges. Emphasis is placed on identifying metabolic risk earlier in the disease trajectory to guide prevention-focused care.
Clinical Application: A core component of this session highlights the use of a visual teaching board during routine clinical encounters to explain metabolic physiology in a clear, non-stigmatizing manner. This low-cost, time-efficient educational tool is used to connect food choices, hormonal signaling, laboratory trends, and appetite regulation in real time, supporting shared decision-making and reducing patient shame. Case-based examples illustrate how this approach improves patient comprehension and facilitates individualized nutrition and lifestyle interventions alongside pharmacologic therapy when indicated.
Implications: By translating complex metabolic concepts into accessible clinical education, clinicians can shift obesity care toward earlier identification of metabolic dysfunction, improved patient engagement, and more sustainable behavior change. This practical framework is designed to be immediately applicable across primary care and obesity medicine settings, supporting comprehensive, physiology-informed obesity management.
