The correct answer is age. Basal metabolic rate (BMR) refers to the amount of energy your body needs to function while at rest. Several factors can influence your BMR, but of the options given, age is the most significant one.
To understand why age affects BMR, it is important to know that as people grow older, their metabolic rate tends to slow down. This is due to a decrease in muscle mass and a decrease in overall physical activity. Muscle mass is an essential component of metabolism as it is metabolically active and burns calories even at rest. Therefore, as you age and lose muscle mass, your BMR decreases.
To get a precise measure of BMR, there are various formulas available, such as the Harris-Benedict equation or the Mifflin-St. Jeor equation, which take into account factors like age, gender, height, and weight. These formulas can provide an estimate of your basal metabolic rate.
Appetite and hunger, although related to metabolism, do not directly affect basal metabolic rate. These factors are influenced by hormonal and psychological factors that control hunger and food intake, but they do not determine the actual energy expenditure at rest.
Daily values, on the other hand, do not affect basal metabolic rate either. Daily values refer to the recommended intake of various nutrients based on a 2,000 calorie diet. They are useful for understanding the nutritional content of food but are not directly linked to metabolism.
age, appetite, and hunger can all affect basal metabolic rate.
Age can affect basal metabolic rate. As a person ages, their metabolism naturally slows down, causing a decrease in basal metabolic rate.
Appetite and hunger can indirectly affect basal metabolic rate. If a person consistently overeats or consumes excess calories, it can lead to weight gain and a higher basal metabolic rate. On the other hand, if a person consistently undereats or restricts their calorie intake, it can lead to weight loss and a lower basal metabolic rate.
Daily values, or recommended daily allowances of nutrients, do not directly affect basal metabolic rate. However, it is important to consume a balanced diet that meets these daily values in order to support a healthy metabolism.
