The estimated daily basal metabolic rate for a man who weighs 150 lb is kcal.

We can not estimate the person basal metabolic rate based on his weight only. We need other information such as age and height or the percentage of the body fat.  

Basal Metabolic Rate (BMR) also known as body metabolism, is the number of calories required to keep our body functioning at rest. In this state, energy will be used only to maintain vital organs, such as the heart, lungs, kidneys, nervous system, intestines, liver, lung, muscles, and skin. To get an accurate measurement, a person should be completely rested.  

There are three versions of BMR measurement, but the one that uses a lot and more accurate than the others is the Mifflin-St Jeor Equation:

For men: BMR = 10Weight + 6.25Height - 5Age + 5

For women: BMR = 10Weight + 6.25Height - 5Age - 161

From the formula above we can conclude that weight, height, and age affected someone BMR.

Factors that affect BMR such as:

An infant's basal metabolic rate

Basal metabolic rate and fever
