Study Notes
Obesity Definitions and Epidemiology
- Overweight and obesity are defined as abnormal or excessive body weight or fat accumulation.
- Body mass index (BMI) is used to classify these conditions. BMI ≥25 kg/m² is considered overweight, and BMI ≥30 kg/m² is obese.
- Worldwide, obesity rates have nearly tripled in the last 30 years, particularly in the United States.
- 71.6% of US adults are overweight or obese.
- 42.5% of US adults are classified as obese.
- Obesity is the 5th leading cause of global deaths.
Learning Objectives
- Define bolded words in the notes.
- Define Basal Metabolic Rate (BMR) and Daily Energy Expenditure (DEE).
- Explain the imbalance of energy input and expenditure leading to obesity.
- Describe the metabolic fate of carbohydrates, proteins, and fats.
- Describe triglyceride storage from ingested fats and carbohydrates.
- Discuss lipogenesis and lipolysis, and their role in free fatty acid availability and fat storage.
- Recognize regulators of lipolysis (hormones, sympathetic nervous system, energy sources).
- Explain processes of appetite and body weight regulation.
- List factors contributing to obesity pathophysiology.
- Explain how nutrition, physical activity, appetite, and medical conditions contribute to obesity development.
- Recognize complications of obesity and visceral fat and mechanisms of obesity-related health problems.
- Recognize signs, symptoms, and components of obesity assessment.
- Calculate body mass index (BMI).
- Classify weight categories based on BMI.
- Recognize cardiovascular risks associated with waist circumference (WC).
- Decide when lifestyle intervention, pharmacotherapy, or bariatric surgery should be considered for obesity management.
- Discuss treatment goals for overweight and obese patients.
- Describe nonpharmacological therapy for managing obesity.
- Identify, describe, and compare/contrast weight-loss medications (classification, MOA, administration, side effects, interactions, and contraindications).
- Explain the relationship between amphetamine and noradrenergic anorectics.
- Differentiate pharmacokinetic phases in obesity drug metabolism.
- Describe the importance of drug metabolism in drug action and elimination.
- Explain how obesity affects pharmacokinetic differences between people.
- Describe drug delivery and medication considerations after bariatric surgery.
- Recognize nutritional deficiencies and supplementation recommendations after bariatric surgery.
- Describe obesity-related complications and monitoring.
- Formulate an evidence-based therapeutic and monitoring plan for initiating and maintaining weight loss.
- Outline clinical controversies surrounding sibutramine, lorcaserin, and fenfluramine/phentermine combination therapy and their reasons for withdrawal.
Nutrition Basics
- The human diet consists of carbohydrates, fats, proteins, and fiber.
- Dietary Reference Intakes (DRI) recommend 45-65% carbohydrates, 20-35% fats, and 10-35% proteins per day.
- Energy needs vary based on age, gender, activity level, medical conditions, etc.
- Basal metabolic rate (BMR) is the energy used for resting functions.
- Diet-induced thermogenesis is the energy needed to digest, absorb, and store nutrients.
- Indirect calorimetry or metabolic gas monitoring are the most accurate ways to measure energy expenditure.
