After completeing the full self assessment, the data gathered was analyzed. Multiple
equations were done to figure out caloric expenditure per day, these equations include
Estimated Energy Requirement (EER), Mifflin-St. Jeor, Harris-Benedict, Owen, and
WHO. From these 5 equations, the caloric energy requirements ranged from 1800 kcal/day
(OWEN) to 2800 kcal/day (EER).
Comparing the five different estimates of caloric expenditure per day to the total
energy intake found on MyPlate Super Tracker Nutritent Analysis, and The Diabetic
Exchange List, show that two of the equations match up with the two different total energy
intakes from each of the analyses. MyPlate Super Tracker indicated a total of 2134 kcal
were consumed in a day, based on the 24 hour recall. This number falls very close to the
estimated caloric expenditure of the Harris Benedict Equation, which estimated a total
caloric expenditure of 2100 kcal/day. The Diabetic Exchange list indicated a total of 1874
kcal were consumed in a day based on the 24 hour recall. This number falls very close to
the estimated caloric expenditure of the Owen Equation, which estimated a total caloric
expenditure of 1800 kcal/day.
As previously mentioned, between MyPlate Super Tracker, and the Diabetic
Exchange List there was about a 250 kcal/consumed difference.
Each of these equations incorporated an activity factor, which increased the amount
of estimated caloric expenditure. The activity factor incorporated into these equations was
1.4, this indicates a very highly active person. Since a high activity factor is being used, it is
safe to assume that MyPlate Super Tracker is more accurate with its estimated overall total
caloric intake, in comparison to the Diabetic Exchange List. Since MyPlate Super Tracker
is thought to be more accurate, the Harris Benedict Equation is the most accurate in this
case for estimating overall caloric expenditure; 2100 kcal/day.
I assumed the MyPlate Super Tracker predicted caloric intake of 2134 kcal/day was
the actual amount of energy I expend, because I have maintained my weight over the past 6
months. For as highly active as I am, by doing enduance and strength training 5 times a
week, if I consumed 1875 kcal/day, which was indicated according to the diabetes exchange
list, I would see weight loss. Maintaining my weight is fine considering my BMI is at 22,
which falls in the healthy range. However, if I wanted to lose weight to achieve a lower
BMI, I would simply decrease caloric intake, while keeping up the same exercise routine.
Lastly, according to MyPlate Super Tracker Analysis I fell within all the
macronutritent recommendations. However, my protein consumption was relatively high
compared to my recommended protein intake. My recommended Protein Intake is 51g/day,
and MyPlate indicated a consumption of 80g/day. Even though strength training does
increase protein needs, 80 g/day is not necessary. A decrease in protein intake is needed
based on this 24 hour recall.
