1. A serving of two cookies has 150 kcal and 12 grams of fat. What percentage of total calories is fat?

Divide fat calories by the kilocalories
Fat – 9 kcal
12g x 9kcal= 108 kcal
108kcal / 150 kcal = .72
.72 x 100 = 72% total calories from fat

2. How many grams of protein are in a 2400kcal diet with 15% of total kcal from protein?

Grams / total kcal = total percentage of kcal from the protein Protein – 4kcal
X / 2400kcal = .15 (15%)
2400kcal x .15 = 360
360 / 4kcal= 90 gm of protein

3. A 1500 kcal diet is 65% carbohydrate. How many kcal come from CHO? How many grams of CHO?

1500kcal = 65% carbohydrate
Carbohydrate = 4kcal
Formula for kcal
Kcal / 1500kcal = 65 % of carbohydrates
X / 1500kcal = .65 (65%)
.65 x 1500 kcal = 975 kcal com from CHO
Formula for grams
Grams of carbohydrates x 4kcal / g = 975 kcal from CHO
975 kcal / 4kcal/g = 243.75 gm of CHO

4. Calculate the grams of fat in a food containing 240 kcal that has 35% of kcal from fat.

Fat = 4kcal
Grams of fat / 240kcal = .35 (35%)
.35 x 240kcal = 84kcal from fat
X x 9kcal = 84 kcal
84 kcal / 9kcal = 9.33 gm of fat

5. Assume that on a particular day you consume 290grams of carbohydrate, 60g fat, and 70g protein. How many kcal did you consume? Determine the percentage of your total energy intake derived from each nutrient.

Carb = 4kcal
Fat = 9 kcal
Protein = 4kcal
Formula for kcal for Carbohydrates
(290gm x 4kcal) + (60gm x 9kcal) + 70gm x 4kcal) = X
1160kcal + 540kcal + 280kcal = 1980 kcal was consumed
Formula for percentage of Carbohydrates
(1160kcal / 1980kcal) 100 = .59
59 %

...Lab: Caloric Content of Food
Purpose: How many calories are in a peanut? How does it compare to other nuts?
Materials: 250 ml beaker, ring stand, paper clip, balance, graduated cylinder, thermometer, aluminum foil, peanut, 2 other types of nuts, lighter.
Background information: We measure the energy that foods give us in terms of Calories. A Calorie is the amount of energy required to raise 1000 grams (1 kg) of water one degree Celsius. Our bodies burn up calories through growth and exercise. When you take in more Calories than you use, the excess Calories are stored in your body as fat. This leads to an increase in one’s weight.
Hypothesis: __________________________________________________
Procedure: 1) Weigh your unshelled peanut on the balance to the nearest
tenth of a gram. Record the weight in the data table.
2) Using the graduated cylinder, measure out 100 ml (100 g) of
water.
3) Carefully pour the water into the beaker and record the temperature of the water (degrees Celsius) in the data table. Leave the thermometer in the beaker.
4) Construct a simple calorimeter as illustrated below:
5) Use a paper clip to make a stand that will hold the peanut above the base of the ring stand.
6) Make a shield around the peanut with aluminum foil. This will help to reduce heat loss to the...

Problem Statement
To develop a program that will help the user in calorie management and determine if the user is balancing their intake with what is being burned by how active they are to help them live a healthier lifestyle.
High-Level View of program solution
The overall goal of this program is to determine daily calories consumed, and what is needed to maintain to stay at a healthy weight. This will be achieved by gathering some vital information. First we start with the user’s age which will begin the first step needed to correctly calculate daily calories. Secondly what is needed is the user’s gender. This is important because it will all for the correct type of body structure for how many calories are needed. Thirdly the user’s height is needed to help with what actual weight the user should be at. Fourthly, current weight is needed to correctly determine the intake of calories that should be consumed to reach a healthy weight. And last is the Basal metabolic rate (BMR). The human body requires a significant amount of energy (i.e. calories) just to function regularly. Each day, your body must breathe, blink, circulate blood, control body temperature, grow new cells, support brain and nerve activity and contract muscles. Staying alive is hard work, people! The amount of energy (in the form of calories) that the body needs to function while resting for 24 hours is known as the BMR. This number of calories reflects how...

MODULE 5: Caloric Content of Food
A) ABSTRACT: This laboratory exercise deals with on how to determine the caloric content of food by creating our own calorimeter. Measuring the energy content of three different food samples by using the change in water temperatures from the heat given off while burning the sample. To verify our results much further — equations, such as energy and heat capacity calculations, helped us establish on such results. As a result of the experiment, I learned and understand better the importance of choosing food with the right caloric content to get us through the day. This experiment made me visually comprehend that various amounts of energy produced by food — which definitely helps our bodies to work efficiently.
B) OBSERVATIONS: During the process of burning the foods, I noticed distinct characteristics of each sample. Firstly, the marshmallow ignited fairly quick and burned in a moderate pace which produced a somewhat sweet smell. Secondly, I noticed that the peanut ignited and burned very slowly, however the burning was controlled; it also produced a roasted aroma and produced a black smoke that tainted the bottom of my beaker. Lastly, the potato chip (Lay’s sour and cream) was at first the least of my concerns, however I was alarmed when the chip ignited really quick and it burned really fast. The fire became bigger halfway of the burned chip, produced a thicker black smoke and didn’t smell like...

...problems (an average of $420 per person), it becomes an issue for the public to debate. Policy Problem: Would requiring all food service locations to publicly post or display calorie counts on menus for all food items served be a cost effective and successful method of decreasing obesity and the diseases caused by obesity in the state of New Avery? Analysts Problem: Determine the causes of obesity and the effectiveness of calorie labeling at changing consumer’s eating habits. Analyze results from calorie labeling in other states, in addition to actions undertaken by the federal government. Look into substitutes to calorie labeling. Identify likely expanders and contractors of this policy. Recognize and weigh externalities, offsetting behaviors, and additional problems related to implementing calorie labeling. Investigate the costs and benefits of implementing this policy. Offer a recommendation in regard to implementing this policy on calorie labeling in the state of New Avery.
Background Information:
Legislative history: As of now, a little less than half of the states in the United States have taken steps toward their own laws requiring food labeling (See Appendix I for a state-by-state summary). The general consensus was to require chain food service establishments to visibly present nutrition labels and calorie labels on their standard menu items. Ultimately, few...

...Many nurses are weak with drug calculations of all sorts. This article will help to review the major concepts related to drug calculations, help walk you through a few exercises, and provide a few exercises you can perform on your own to check your skills. There are many reference books available to review basic math skills, if you find that you have difficulty with even the basic conversion exercises.
Common Conversions:
1 Liter = 1000 Milliliters
1 Gram = 1000 Milligrams
1 Milligram = 1000 Micrograms
1 Kilogram = 2.2 pounds
Methods of Calculation
Any of the following three methods can be used to perform drug calculations. Please review all three methods and select the one that works for you. It is important to practice the method that you prefer to become proficient in calculating drug dosages.
Remember: Before doing the calculation, convert units of measurement to one system.
I. Basic Formula: Frequently used to calculate drug dosages.
D (Desired dose)
H (Dose on hand)
V (Vehicle-tablet or liquid)
D
H
x V = Amount to Give
D = dose ordered or desired dose
H = dose on container label or dose on hand
V = form and amount in which drug comes (tablet, capsule, liquid)
Example:
Order-Dilantin 50 mg p.o. TID
Drug available-Dilantin 125 mg/5ml
D=50 mg
H=125 mg
V=5 ml

...Grade Average Calculation
There are 3 grade averages: TGA, CGA and GGA.
TGA (Term Grade Average) is the combined grade average covering all courses taken in the term and
the session immediately following.
CGA (Cumulative Grade Average) is computed based on all the courses taken by the student which
are expected at the time of calculation to be applied towards the degree requirements in the current
program.
TGA & CGA =
Sum of (Course Credits x Course grade points)
Sum of Course Credits
GGA (Graduation Grade Average) is calculated at graduation from the courses that are presented for
the award of a degree. Courses taken in the first year of study are given a half-weight. Students who
enter the University with credit transfer of 10 credits or more are not eligible for this half-weight
concession.
Note:
a) Credits/grades that are omitted from grade average calculations
Transfer credits and courses graded AU, I, P, PP or W are omitted from the calculation of all three grade averages.
b) Calculation of ‘F’ grades
For failed courses which are repeated, the new grade obtained after repeating the course will replace the previous
F grade and course credits are only counted once in the calculation of CGA and GGA.
c) Uncleared ‘F’ Grades
For failed courses which are not repeated, the uncleared ‘F’ grades will be included in the CGA and GGA
calculations (the grade averages will be pulled...

According to these calculations, the schedule variance is running late and the cost variance did not run over. The SPI is 1.0 which means that it is running on schedule. The CPI is .98 which is over budget by .02%. I don’t feel that the project is too far off schedule which they should be able to celebrate.
