Analysis:
Energy Balance
1 (10 pts) Cronometer uses the Mifflin-St Jeor equation for estimating energy expenditure ("Calories Burned"). How do the provided energy needs from Cronometer compare with the calories you consumed, on average, in Table 1? Are you in energy balance, positive energy balance, or negative energy balance based on the Mifflin-St Jeor estimate? Include the numeric values in your answer.
The energy needs from Cronometer indicate that I should take a total of 2684 kcal a day, whereas my average intake was 2174 kcal. Based on this estimate, my body is in a negative energy balance because I took fewer calories than required, with a deficit of 510 kcal.
2 (15 pts) Calculate your energy needs using the Estimated Energy Requirements (EER) equation that you learned about in Chapter 11 of the text. You will need to convert your height and weight to the appropriate units. Be sure to include your work. How do your calculated energy needs compare with the calories you consumed, on average, in Table 1? Are you in energy balance, positive energy balance, or negative energy balance based on the EER estimate?
EER (men) = 662 - (9.53 × age in years) + PA × (15.91 × weight in Kg + 539.6 × height in meters)
EER = 662 - (9.53 × 25) + 1.25 × (15.91 × 86.183 +539.6 × 1.7018)
662 - (9.53 × 25) + 1.25 × (1371.1715 + 918.2913)
662 - (9.53 × 25) + 1.25 × 2289.4628
662 - 238.25 + 2861.8285
423.75 + 2861.8285
3285.58 kcal
The energy needs based on the EER equation indicate that I should take 3285.58 kcal per day, which is more than my average consumpti...
