A basal metabolic rate (BMR) of 1,500 calories for men is considered to be relatively high. The average BMR for adult men is 1,200-1,400 calories per day, while that of women is slightly lower at 1,000-1,200 calories per day.

BMR is the amount of energy that your body burns at rest. It is an important indicator of physical health, and it is influenced by a number of factors, including age, sex, height, weight, muscle mass, and activity level.

A higher BMR means that your body burns more calories at rest, even if you are not doing any physical activity. This can be beneficial for weight loss or maintenance.

What factors can affect BMR?

A number of factors can affect BMR, including:

• Age: As you age, your BMR tends to decrease. This is because you lose muscle mass and your metabolism slows down.
• Sex: Men typically have a higher BMR than women. This is because men have more muscle mass.
• Height and weight: Taller and heavier people tend to have a higher BMR. This is because they have more body mass to maintain.
• Muscle mass: Muscle burns more calories than fat, so people with more muscle mass tend to have a higher BMR.
• Activity level: People who are more active tend to have a higher BMR. This is because their bodies have to work harder to maintain their activity levels.

How to maintain a healthy BMR

There are a number of things you can do to maintain a healthy BMR, including:

• Exercising regularly: Exercise helps to build muscle and boost your metabolism.
• Eating a healthy diet: Eating a healthy diet that is rich in protein and complex carbohydrates can help to maintain your muscle mass and metabolism.
• Getting enough sleep: When you don't get enough sleep, your body produces more of the stress hormone cortisol, which can lower your BMR.
