Winter 2012 Series Put Some Pep In Your Step Cory Scheadler & Alex Lucas
Winter 2012 Series What is a Calorie A calorie = Energy contained in a food substance. A single calorie = energy required to temperature of 1g water by 1°C 1 kilocalorie (kcal) = 1 Calorie 1g CHO = 4 kcal 1g Protein = 4 kcal 1g Fat = 9 kcal 1g Alcohol = 7kcal
Winter 2012 Series How Does Your Body Use Calories? Calories = Fuel source = Energy (E) Energy is required to maintain life Basal Metabolic Rate (BMR) - lowest E to sustain life. ≈ Resting Metabolic Rate (RMR) E used at rest. Thermic Effect of Food (TEF)- E required to use food eaten (CHO<Protein) Thermic Effect of Activity (TEA)- E required for activity So BMR+TEF+TEA = daily total
Winter 2012 Series How can understanding Expenditure Intake Calories be of value? TEF PHYSICAL ACTIVITY FOOD BMR

Winter 2012 Series Practical implications Taking in less Calories – Low Fat vs. Low Calorie Expending more calories – Extra day of exercise Incidental PA (stairs, parking further away)
Winter 2012 Series Examples of changing your exercise routine For a person typically exercising 2 x p/week for 1 hour 20 minutes treadmill walking -4 kcal x 20mins = 80 kcal 40 minutes weight lifting -(moderate)5 kcal x 40 = 200 kcal = 280 – 300 kcal per session (approx) = 560 – 600 kcal per week Adding 1 extra workout day or half an hour of walking = 600 + 120 = 720 kcal Or walking faster, or higher grade = 5kcal x 30 = 150 kcal
Winter 2012 Series Examples of changing diet Eating smaller portions – Serving sizes Eating Smaller meals more often (TEF) Applebee’s Choosing lower calorie options choc chip Sundae Treat type foods less often - 1580 kcal
