This is the Harris Benedict Formula for men.
655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) - ( 4.7 x age in years )
66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) - ( 6.8 x age in year )
Which on of these does not correctly match its function
Sedentary (little or no exercise) : BMR x 1.2
Lightly active (light exercise/sports 3-5 days/week) : BMR x 1.557
Very active (hard exercise/sports 6-7 days a week) : BMR x 1.725
Extra active (very hard exercise/sports & physical job or 2x training) : BMR x 1.9

Feed center, satiety center
signals satiety when adipose stores are increasing
signals appetite when adipose stores are decreasing
