Energy Homeostasis
Definition
Energy homeostasis is the body's way of balancing the energy we consume with the energy we expend to maintain body weight and proper physiological function.
Scientific / Technical Definition
Energy homeostasis refers to the complex biological process through which organisms regulate the balance between caloric intake from food and energy expenditure through basal metabolic rate, physical activity, and thermogenesis. This process is crucial for maintaining a stable body weight and is regulated by multiple signals in the central nervous system and peripheral tissues.
Benefits
- Helps maintain a stable body weight
- Supports optimal metabolic health
- Regulates hunger and satiety
- Prevents obesity-related diseases
Examples
- Using energy from food to fuel daily activities
- Adapting to changes in food intake by adjusting energy expenditure
Additional Information
- Importance: Energy homeostasis is crucial for preventing obesity and metabolic disorders by ensuring that energy intake does not consistently exceed energy expenditure.
