Lipolysis

Definition

Lipolysis is the process where the body breaks down fats into fatty acids and glycerol for energy.

Scientific / Technical Definition

Lipolysis is a metabolic pathway through which triglycerides, stored in fat cells, are hydrolyzed into free fatty acids and glycerol. This process is catalyzed mainly by the enzyme hormone-sensitive lipase and occurs in response to hormonal signals, particularly during fasting, exercise, or calorie restriction.

Benefits

• Facilitates energy release from fat stores
• Supports weight loss through fat metabolism
• Helps maintain blood glucose levels during fasting

Examples

• Release of fatty acids during exercise
• Fat breakdown during fasting periods

Additional Information

• Effects: This process allows the body to use stored fats for energy, especially during times when carbohydrates are not available, thus supporting prolonged physical activity and maintaining energy balance in the body.
