| BMI | The Body Mass Index estimates human body fat based on the individual’s weight and height. | |
| with | BMI = 703*w/h2 | |
| where | w = weight (in pounds) h = height (in inches) |
|
| At Rest BMR | The Basal Metabolic Rate is the minimal amount of energy expended while at rest. | |
| with | BMR (Men) = 6.23w + 12.7h – 6.76a + 66 BMR (Women) = 4.338w + 4.698h – 4.68a + 655 |
|
| where | w = weight (in pounds) h = height (in inches) a = age (in years) |
|
| Calories Burned | Calories Burned measures the amount of calories burned during an exercise. In order to lose 1 kg of body fat (3500 kCal) per week you must expend 500 cal/day. | |
| with | Calories Burned = (METS)(w)(t)/125.7143 | |
| where | METS = metabolic equivalents of the exercise w = weight (in pounds) t = time (in minutes) |
|
| Active BMR | The Active BMR adjusts the BMR value based on the amount of daily activity. | |
| with | Active BMR = Activity Factor x BMR | |
| where | Activity Factor = a multiplier based on the individual exercise activity | |
| METS | (Metabolic Equivalents) are multiples of the resting metabolic rate due to exercise, where 1 MET = 3.5 cal/kg of body weight. | |
