Thermogenesis

Definition

The process of heat production by the body via the combustion of nutrients and metabolic activity. It accounts for approximately 10% of total energy expenditure.

How it works

Thermogenesis is the body's ability to convert chemical energy from food into heat. There are three types: basal thermogenesis (resting metabolism), thermogenesis associated with physical activity, and post-prandial thermogenesis (digestion of food). This process is crucial for maintaining body temperature and contributes to daily caloric expenditure.

Role

Regulates body temperature and contributes to global energy expenditure.

Examples

• Shivering in cold
• Sweating during exercise
• Digestion of food
• Activation of brown adipose tissue

Recommendations

Maintain regular physical activity to stimulate thermogenesis. Moderate cold exposure can also increase this process. A protein-rich diet favors post-prandial thermogenesis.

Key takeaway

Thermogenesis is a key mechanism of energy expenditure that can be stimulated by exercise and nutrition.
