The Energy EquationEnergy equation: the food (or energy) we take in should closely match the effort we put outEnergy storage = Energy intake Energy output

Basal and Resting Metabolic RateMetabolic rate (MR) Measures energy that needs to be consumed in order to sustain essential bodily functionsAffected by age, sex, weight, lean muscle mass, and general level of physical fitnessTwo measures are distinguished:Basal metabolic rate (BMR)Measures MR under rigorous conditionsResting metabolic rate (RMR)Measures MR under less rigorous conditionsMost common measurement in practice

Calculating MRM- Weight (lbs) x 11= MRF- Weight (lbs) x 10 = MRCalculate the MR for a 130lbs woman.MR= 130 x 10 1300 calories/day

Estimating Daily Caloric Need from Metabolic Rate Activity Factors Sedentary= 1.4Moderately Active= 1.6Highly Active= 1.8 Estimate daily Caloric Need from MRM Weight (lbs) x 11 x activity factor= energy ouput

F Weight (lbs) x 10 x activity factor= energy output

Calculate the daily caloric needs for a highly active 125 lbs female athlete

125x10x1.8=2250c/day

Calculating Energy Balance Calculate the energy balance for a highly active 128 lbs woman who has a daily caloric intake of 2000 kcal/dayEnergy intake= 2000kcal/dayEnergy output=128x10x1.8=2304

Therefore the individual may lose weight

Harris-Benedict EquationHarris-Benedict EquationUsed to calculate your RMRSeparate calculations for males and females

Males: RMR = 66.5 + (5H) + (13.7W) (6.8A)*

Females: RMR = 665 + (1.9H) = (9.5W) (4.7A)*

*H = height in centimetres W = weight in kilograms A = age in yearsBob weighs 68kg, is 168 cm tall and is 22 years old. What is his RMR

RMR= 66.5 + (5x168) + (13.7 x 68) (6.8 x 22)

=66.5+ 804+ 931.6+-149.6=1,653 c/day

BMI Used to measure extent to which individuals are balancing the energy equation (over or underweight relative to height)BMI correlates well with increased risk of disease, particularly cardiovascular, pancreatic and kidney

BMI- ration of a persons weight in KG to the square of his/her height in metres BMI=weight/height2
