It’s difficult to say what a “normal” BMR is because it’s influenced by many variables such as weight, muscle mass, height, sex, age, and lifestyle.
For example, children tend to have a higher BMR for their size compared to adults because of their relatively fast growth and development, and men tend to have a higher BMR than women because they normally have more muscle mass. What’s more, BMR tends to be lower in older adults compared to younger adults since muscle mass normally decreases with age.
That said, most healthy adult women will have a BMR of around 1,300 to 1,500 calories per day and adult men will have a BMR of around 1,600 to 1,800 calories per day.
