Calculating your Basal Metabolic Rate (BMR)
The Schofield equation is the name of a formula used to calculate an individual's basal metabolic rate (BMR). Basal metabolism is the amount of energy a body needs to use to sustain life. Energy is needed for metabolism at the cellular level, synthesis of hormones and enzymes, temperature maintenance, muscle movement and more. The BMR measures the basal metabolism over a given period of time, usually over the course of 24 hours. The Schofield equation is actually one of a set of equations that calculates minimal daily caloric needs to avoid weight loss based upon an individual's age group and sex.
Internet calculators are available to perform Schofield equations. A table, however, is the easiest way to identify how an individual's age and sex influence the appropriate Schofield equation necessary to determine the basal metabolic rate. As indicated in the table below, men have a higher overall BMR than women and younger individuals have higher BMRs than do their elders. The larger than expected constant of 14.8 under the female column for those aged 18 to 30 represents the higher caloric expenditures typical of pregnancy and lactation. The overall greater BMR of men over that of women is attributed to their body composition. Men have a larger ratio of muscle to fat, in addition to their typically greater amount of physical activity.

How can you use your BMR?
You can use your BMR to calculate your daily energy requirements, i.e. your calorie intake requirements. You do this by referring to your Physical Activity Level (PAL).
What is your PAL?
Sedentary or light activities = Men and Women 1.4
Active or moderately active = Women 1.6
Men 1.7
Vigorous active lifestyle = Women 1.8
Men 1.9
Your daily Calorie Intake = Your BMR x Your PAL value
Example
Woman aged 36 weighing 65 Kilos BMR equation (8.3 x 65) + 846 = 1385.5
She is moderately active PAL = 1.6
BMR (1385.5) x PAL (1.6) = 2219 kcals/day
Remember - this calculation represents the calorie intake required to remain the same weight!
