Metabolic Adaptation
Definition
Metabolic adaptation is the process by which the body adjusts its metabolism in response to changes in diet and energy intake. It can slow down or speed up your metabolism based on factors like calorie intake and physical activity.
Scientific / Technical Definition
Metabolic adaptation, also known as adaptive thermogenesis, refers to the body's ability to modify its energy expenditure in response to changes in energy intake and expenditure. This adaptation helps the body maintain energy balance and body weight over time, often making it challenging to lose weight as the body conserves energy more efficiently during calorie restriction.
Benefits
- Helps maintain energy balance.
- Conserves energy during periods of caloric restriction.
- Can adjust metabolic rate based on dietary intake and physical activity.
Examples
- Reduction in resting metabolic rate during a calorie deficit.
- Increase in energy expenditure with higher physical activity.
Additional Information
- Effects: Metabolic adaptation can make weight loss challenging as it lowers the resting metabolic rate, causing the body to burn fewer calories to preserve energy.
