Resting metabolic rate (RMR) can be affected by
several factors, such as:
1. Age: RMR tends to decrease with age as a result of natural physiological changes and a decrease in muscle mass.
2. Body composition: RMR is influenced by the proportion of lean muscle mass to body fat. Muscle tissue is more metabolically active than fat, so individuals with a higher muscle mass generally have a higher RMR.
3. Gender: Men typically have a higher RMR compared to women due to differences in body composition and hormonal influences.
4. Weight: RMR generally increases with body weight, as larger bodies require more energy to maintain basic bodily functions.
5. Genetics: There may be genetic variations that affect RMR, although the exact relationship is still not fully understood.
6. Hormonal factors: Thyroid hormone levels, for example, can influence RMR. An underactive thyroid (hypothyroidism) can slow down metabolic rate, while an overactive thyroid (hyperthyroidism) can increase it.
7. Environmental factors: Extreme temperatures, such as very cold or hot environments, can also temporarily affect RMR as the body works to regulate its internal temperature.
It's important to keep in mind that while these factors can influence RMR, they are not the sole determinants. Each individual's metabolic rate is unique and can be influenced by a combination of these factors as well as other lifestyle and health factors.
Why is it important to recognize hunger versus appetite?(1 point)ResponsesIf you eat too many calories you will lose too much weight.If you eat too many calories you will lose too much weight.You should only eat as many calories as your body needs.You should only eat as many calories as your body needs.Hunger makes you eat based on emotions not nutrition.Hunger makes you eat based on emotions not nutrition.Your appetite tells you when your body needs nutrients.
The correct response is: You should only eat as many calories as your body needs.
It is important to recognize and distinguish between hunger and appetite because hunger is the physiological need for food to satisfy energy and nutrient requirements, while appetite refers to the desire or pleasure associated with eating. Understanding this distinction helps in making informed food choices and maintaining a healthy body weight.
If you eat based solely on appetite without considering hunger cues, you may consume unnecessary calories and exceed your body's energy needs, which can lead to weight gain and other health issues. On the other hand, if you ignore or suppress hunger signals and restrict calorie intake excessively, you may not provide your body with enough nutrients to support proper bodily functions.
By recognizing true hunger and eating as many calories as your body needs, you can maintain a balanced and sustainable approach to nutrition and promote overall well-being.
