Lipid Mobilization

Definition

Lipid mobilization is the process by which fats stored in the body are broken down and released into the bloodstream for use as energy.

Scientific / Technical Definition

Lipid mobilization refers to the biochemical process where triglycerides stored in adipose tissue are hydrolyzed into free fatty acids and glycerol, which can then be transported in the blood to tissues where they are oxidized for energy production. This process is crucial during fasting, intense exercise, or periods of caloric deficit.

Benefits

• Provides energy during fasting or physical exertion
• Helps maintain energy balance in the body
• Supports metabolic adaptation to changes in dietary intake

Examples

• Fatty acids released from adipose tissue
• Glycerol used in gluconeogenesis

Additional Information

• Effects: Lipid mobilization plays a critical role in energy homeostasis, especially in periods of energy deficit, and aids in the adaptation to fasting or ketogenic diets.
