From the Guidelines
Fat metabolism can be modified in clinical practice through comprehensive lifestyle interventions, including dietary modifications and increased physical activity, as recommended by the most recent guidelines 1.
Key Components of Fat Metabolism Modification
- Dietary Modifications: An individualized dietary intervention that reduces overall calorie intake by at least 500 kcal/day, with sufficient protein, vitamins, and minerals, is recommended for initial weight loss and maintenance in adults 1.
- Physical Activity: Clinicians should encourage adults with overweight or obesity to devote 30–60 min per day to moderate-intensity aerobic exercise, at least 5 days per week (≥150 min per week) 1.
- Behavior Modification: A comprehensive lifestyle intervention program that includes diet modification, increased physical activity, and behavior modification is fundamental in obesity management 1.
Pharmacological Interventions
- GLP-1 Receptor Agonists: For patients with obesity, GLP-1 receptor agonists like semaglutide or tirzepatide can enhance fat metabolism by improving insulin sensitivity and reducing appetite 1.
- Orlistat and Liraglutide: Currently, orlistat and liraglutide 3.0 mg are approved for use in adolescents (>12 years) in several Asian countries, and may be considered for adolescents with obesity who have severe complications or have not responded to lifestyle modification 1.
Surgical Interventions
- Bariatric and Metabolic Surgery: Bariatric and metabolic surgery may be used as an adjunct therapy to lifestyle modification, with or without pharmacotherapy, to improve or maintain weight loss and to control obesity-related complications 1.
Monitoring and Follow-up
- Regular Evaluation: Clinicians should evaluate the effectiveness of lifestyle changes within 3 months, and consider intensive lifestyle therapy, pharmacotherapy, or surgical referral for individuals showing minimal weight loss at this time 1.

From the Research
Definition of Fat Metabolism
Fat metabolism refers to the process by which the body breaks down and utilizes fats for energy. This process involves the conversion of fatty acids into acetyl-CoA, which can then be used to produce energy through the citric acid cycle and oxidative phosphorylation.
Modification of Fat Metabolism in Clinical Practice
Fat metabolism can be modified in clinical practice through various means, including:
- Dietary changes: Modifying the type and amount of dietary fat can impact fat metabolism. For example, increasing the intake of polyunsaturated fatty acids, such as omega-3 and omega-6 fatty acids, can improve insulin sensitivity 2, 3.
- Pharmacological interventions: Certain medications, such as orlistat, can reduce fat absorption and improve metabolic parameters, including insulin sensitivity and lipid profiles 4.
- Nutritional supplements: Omega-3 fatty acid supplements have been shown to have a favorable effect on insulin resistance and metabolic parameters 3.
Role of Fatty Acids in Fat Metabolism
Fatty acids play a crucial role in fat metabolism, and their composition can impact insulin sensitivity and metabolic health. For example:
- Saturated fatty acids can impair insulin sensitivity, while polyunsaturated fatty acids can improve it 2, 5.
- Omega-3 fatty acids have been shown to have anti-inflammatory effects and improve metabolic parameters 3.
Clinical Implications
Understanding the role of fatty acids in fat metabolism can inform clinical practice and guide the development of therapeutic strategies for managing metabolic disorders, such as insulin resistance and type 2 diabetes. For example, modifying dietary fat composition and using pharmacological interventions, such as orlistat, can improve metabolic parameters and reduce the risk of cardiovascular disease 2, 4, 3.
