Alex, Kim, and Jenna have different levels of activity, and thus require a varied amount of calories per day. Alex is an athlete, and he requires 3500 calories per day to fuel his high intensity activity. Jenna is a secretary and is sedentary most of her day. Her low level of activity requires a mere 1800 calories a day, while Kim, a professional dancer, needs 2800 calories per day to fuel her moderate level of activity.
| Jenna | Kim | Alex | |
| Profession | Secretary | Professional Dancer | Athlete |
| Level of Activity | Low | Moderate | High |
| Caloric Needs | 1800 Calories/Day | 2800 Calories/Day | 3500 Calories/Day |
Fats are broken down in cellular respiration to generate the ATP needed to fuel our bodies. According to the Food and Drug Administration (FDA), the Percent Recommended Daily value for fats in a balanced diet should not exceed more than 30% of the total daily calorie intake. Fats provide 9 calories per gram.
Nutritional needs of Jenna
What question would this calculation answer?
Finding 30% of 1800 calories and then dividing by 9 calories per gram.
1800 calories x 0.30 = 440 calories
440 calories/9 calories per gram = 49 grams
Multiple Choice
How many grams of fat can Jenna consume in one meal?
How many fat calories can Jenna consume each day?
How many calories are found in 9 grams of fat?
How many grams of fat can Jenna consume each day?

synthesize water from hydrogen and oxygen.
break down water into hydrogen and oxygen.
move hydrogen ions across cell membranes.

Part 5
As protons move through the proton pump,
Multiple Choice
the membrane becomes more permeable to the hydrogen ions.
the concentration of hydrogen ions inside and outside the cell reaches equilibrium.
they build up on one side of the membrane, producing a concentration gradient.
conformational changes occur within the membrane proteins.
Part 6

True/False
Overall Caloric Distribution (10 points)
Average kcals consumed ________________
Percent of goal for kcal _________________________ (kcals consumed divided by recommended kcal * 100)
Since carbohydrate and fat are largely used to meet kcal needs, it makes sense to look at our intake in terms of percent of total kcal rather than in absolute gram amounts.
Record the percent of kcals coming from carbohydrate and fat in your diet in the chart below. Do not confuse the percent of kcals with the percent of a goal.
To calculate, use the following formulas:
Determine number of kcals from each macronutrient consumed on an average day
kcals from CHO = grams of CHO consumed per avg. day X 4 kcals per g CHO
kcals from FAT = grams of FAT consumed per avg. day X 9 kcals per g FAT
Divide number of kcals from each macronutrient by total day kcals consumed
% of total daily kcals from CHO = kcals from CHO / total daily kcals
% of total daily kcals from FAT = kcals from FAT/ total daily kcals
(Ex. 200 grams of CHO consumed * 4 kcals per g CHO = 800 kcals of carbohydrate. 800 kcals of carbs / 2400 kcals total consumed = .33 * 100 = 33% or 33% of kcals came from carbohydrate)
| Macronutrient | Recommended percent of kcal | Percent of kcal from nutrient in your diet |
| Carbohydrate | 45 - 65 % of kcals | |
| Fat | 20-35% of kcals |
Did you consume the appropriate percent of kcal from carbohydrates, protein and fat? If not, how might you adjust your kcal to better meet the recommendations and what changes in your food intake could accomplish this?
Carbohydrate Intake - Further Analysis (6 points)
*note: if you are using myplate, ignore the recommendation of 130 grams for total carbohydrate on your printout.....that is a minimum not a recommended amount
3. Average grams of fiber consumed ______________________.
4. Percent of goal for fiber ________________________ (average fiber consumed divided by fiber recommended * 100)
5. Are you getting enough fiber (100% of goal for question 4)? If not, how might you fix this?
6. Take a look at your list of foods....are lots of your kcals coming from sugar? Only 10% or less of your total kcals should be coming from refined (added) sugar...how do you think you did? ______________________________________________
Fat Intake - Further Analysis (8 points)
7. Average grams of saturated fat consumer per day:_______________________
8. Percent of kcals from saturated fat per day: ______________________________ (Hint: average grams of sat. fat consumed times 9 kcals per gram divided by total kcals consumed)
9. Did you consume more that 10% of your kcals from saturated fat? If so, how might you reduce saturated fat?
(you do not need to be worried about consuming too little since there are no essential fatty acids that are saturated)
note: if you are using diet analysis plus to evaluate your diet, you can look at the spreadsheet report to see how much of a given nutrient is in each food that you ate.. For example, if your saturated fat were high, you could look at the spreadsheet report to see what foods contributed the most saturated fat to the diet. You can then think about reducing portion size or making substitutions
10. Average milligrams of cholesterol per day: ____________________________________. Are you consuming more than 300 milligrams of cholesterol? If so, how might you reduce this?
11. Are you consuming foods rich in omega-3 fatty acids? If so, what are they? If not, how might you increase your intake of omega-3 fatty acids?
Protein Intake - Further Analysis (6 points)
12. What is your protein RDA? (Multiply your body weight in kilograms by 0.8 g PRO/kg)
13. Are you consuming an appropriate amount of protein? (Recommendation is to consume a minimum of the RDA amount and a maximum of twice the RDA)
14. If you are not within the range indicated in question 13, indicate how you might adjust your diet.
