There are several factors that can affect resting metabolic rate (RMR):
1. Body composition: Muscle mass is metabolically more active than fat mass, so individuals with higher muscle mass tend to have higher RMR.
2. Age: RMR tends to decrease with age due to muscle loss and reduction in activity levels.
3. Gender: Men generally have a higher RMR than women due to higher muscle mass.
4. Hormones: Thyroid hormones play a significant role in regulating RMR. An imbalance in thyroid hormone levels can affect RMR.
5. Diet and nutrition: Low-calorie or restrictive diets can lower RMR as the body adapts to conserve energy. Conversely, overeating can increase RMR temporarily.
6. Physical activity level: Regular exercise and increased physical activity can raise RMR as it contributes to muscle development and overall metabolic demand.
7. Genetics: Some individuals may have naturally higher or lower RMR due to genetic factors.
8. Stress: Chronic stress and lack of sleep can impact hormones that regulate RMR, leading to lower metabolic rates.
9. Environmental factors: Extreme temperatures (hot or cold) can slightly increase RMR as the body works to maintain core temperature.
10. Medications: Certain medications, such as those used for thyroid disorders or as appetite suppressants, can affect RMR.
It's important to note that while these factors can influence RMR, the magnitude of their impact may vary among individuals.
