PROJECT PROPOSAL

    The total energy requirement of an individual is dependent upon the amount of energy required for maintaining basal metabolism, physical activity, sleep, growth, pregnancy, lactation, rehabilitation from disease or inactivity, the specific dynamic effect, and the maintenance of ideal body temperature.  It is apparent that we are all different physically, therefore, we require different needs in order to maintain a healthy lifestyle, including diet.  I want to calculate from a formula; the total calorie intake for individuals based on their weight and their activities over a 24-hour day.  With this in mind, I will compare this approximate calorie intake to the actual calorie intake for the particular individual.  The purpose of comparing these two-calorie totals is to determine how the individual can come close to the calculated amount.  It is important for a person, especially an active person to meet their daily caloric needs if they want to be healthy, and perform at their very best.
 It is apparent that carbohydrates, proteins, and fats are essential for a well-balanced diet.  Some individuals require more or less of these nutrients based on the activities they participate in.
 Therefore, in my project, I have set up a model that calculates the total requirement of daily calorie intake based on weight and regular activity.  Based on the activities, I suggest the appropriate energy bar that fits the needs of the individual, as a supplement to fulfill the need of certain calorie intake and/or for the nutrients, such as carbohydrates, proteins, and fats.

Formula for Calculating Daily
Calorie Requirement

w = weight in lbs.
(w/2.2) = conversion of lbs. to kilograms
6: 6 segments/hour;
calorie per lb. per activity determined by table

Basal calculation for non-sleeping hours:
(w/2.2)(1cal/kg)(non-sleeping hours)

Sleeping calories during sleeping hours:
 (w/2.2)(0.9(1)cal/kg)(sleeping hours)

Activity calories:
6[(calorie per lb. per activity)(hours for activity) + others]
 

Example


Weight:150 lbs.
Hours of Activity: 17
Sleep Hours: 7
Activities: walking 2mph - 4.5 hrs
                   sitting (TV) - 4 hrs.
                   washing/dressing - 1 hr
                   standing (light activity) - 4 hrs.
                   general HW - 4hrs.
                   walking upstairs - 1/4 hr.
                   walking downstairs - 1/4 hr.
Actual Calories: ~ 1,360 calories

Using the Formula

Basal calculation for non-sleeping hours:
(150/2.2)(1cal./kg)(17)
= 1,159

Calories during sleeping hours:
(150/2.2)(.9((1)7)
= 430

Activity Calories:
6[(35)(4.5) = (12)(4) + (24)(3) + (12)(1) + (41)(4) + (175)(0.25)  + (67)((0.25)]
= 3,204

Result with 10% Energy from Food:
1.1(1,159 + 430 + 3,204)
= 5,272

Analysis

We can interpret this result by stating that an adequate amount
of calories are necessary for me based on the weight,
activities, and the time factor. Although, the
Balance Bar with the 40-30-30 ratio would be a good
bar to eat because it would give  some calories and the energy
to continue throughout the day. There are more sugars and fats included
in the bar, along with a good concentrated amount of carbohydrates and protein.
