her dog for 30 minutes most afternoons and swims on a Tuesday and Thursday (light activity level).
Six weeks ago, Alice started training for an upcoming 10-kilometre fun run with her work colleagues.
She has added three running sessions a week (Monday, Wednesday and Saturday) (moderate
activity). Since increasing her training load, Alice has been feeling quite tired and has noticed her
clothes are becoming loose. She has not actively been trying to lose weight and four weeks ago her
weight was stable at 61kg of which she was happy with. Her doctor has ruled out any medical issues

Gavin is a mechanic and works at a local garage Monday – Friday. He is also an active member of the
army reserve where he works as a vehicle mechanic. His commitment to the reserves is one night a
week at the local army barracks. He also attends six training weekends a year and one annual twoweek deployment. As an active member of the military, Gavin is required to maintain a level of
physical fitness that is tested annually. To keep in shape, he trains regularly at the gym (weights),
runs and swims at the local pool (overall moderate activity). At his annual physical he mentioned to
the military doctor that he has some issues with mild constipation. The doctor ruled out any medical
cause and discussed his diet, in particular dietary fibre and fluid. Gavin has come to you for advice as
he thinks his diet is reasonable. He reports his usual intake as:
Breakfast: 60g Rice Bubbles, 1 cup of full cream milk, 2 slices toast (white bread with 10g
of polyunsaturated spread and 1 tablespoon jam), 125mL strained orange juice
Snack: 3 plain sweet biscuits and 1 cup of tea (190mL water and 60mL milk)
Lunch: 2 hardboiled eggs mashed on a medium white bread roll 10g of
polyunsaturated spread, 125mL apple juice

Dinner: 250g steak (rump) cooked in 7g canola oil, 1 cup plain mashed potato (300g), ½
cup cooked pumpkin and ½ cup cooked cauliflower, 1 cup of tea (190mL water
and 60mL milk) 2 slices white bread with 10g polyunsatured spread
Snack: 1 packet of crisps (60g)
Drinks: Nil additional to drinks reported above
Foodworks analysis of reported diet:
Total Energy: 11200kJ Protein: 153g Total Fat: 86g (saturated fat: 28g) Carbohydrate: 310g Dietary
Fibre: 20g Total water (food and fluids): 2000g

Written Response:
Part 1 Evaluation:
Using the information provided, assess Gavin’s dietary intake and create a summary statement that
interprets the dietary intake in relation to dietary fibre consumed and its food sources. What dietary
advice would you provide in relation to his dietary fibre intake? Provide two specific suggestions for
each meal and justify your recommendations. What recommendations would you provide regarding
his fluid intake?
Part 2 Follow-up appointment:
After four weeks, Gavin returns to you for a follow up appointment. He states he has been following
all your recommendations, however there is no improvement in his bowels. He asks if he should take
a laxative. What advice would you give to Gavin?

Nik is recently divorced and living alone. His ex-wife has custody of their 7-year old son Ben. Each
weekend Ben stays with Nik and Ben is keen to start nippers at the local surf club. Nik would like to
be involved in water safety at nippers but to do this he must complete the surf rescue certificate
which requires a standard of fitness. Nik realises he is “out of shape” and has come to you for
dietary advice. He thinks he needs to lose weight and would like some help with meal planning. Two
weeks ago, he joined an adult swimming squad and is consistently swimming three mornings a week
before work with the squad. On swimming days, he swims from 6am-7am (moderate activity) and
goes straight to work. He works in an office and is generally sedentary during the day. Nik reports
that since starting his new training regime, he has lost approximately 2 kilograms, and reports his
current weight is now 93kg. Nik has completed a food diary for the last seven consecutive days (a
sample day is shown below). A FoodWorks analysis of the 7-day food diary shows a mean energy
intake of approximately 17MJ over the seven-day period. This is comprised of 46% carbohydrate,
10% protein, 31% total fat (of which 60 grams is saturated) and 13% from alcohol.
Breakfast: Skips because he is either running late for work or swimming. Has an instant coffee
made with water and about 30mL of milk
The local bakery has a lunch deal of a beef pie with a 500mL chocolate milk. Once a
week he goes with his workmates to the local pub for a counter lunch (steak, fries
and Caesar salad plus 2-3 beers)
Varies but is usually take away as he is not often motivated to cook, his usual choices:
Kentucky Fried Chicken dinner meal; Dominos meat lovers pizza; pub meal of chicken
parmigiana and chips; 4-5 beers.
Snacks: Salt and vinegar chips (usually when watching television at night); chocolate coated

the following:
1. Given the body composition data presented, interpret Nik’s overall disease risk.
2. Comment on the macronutrient distribution of Nik’s diet in comparison to the acceptable
macronutrient distribution ranges (AMDR).

Case Study 4: Lihua
Age: 20 years
Weight: 68 kg
Height: 170 cm

Lihua is a third year University student studying pharmacy. She lives with her parents and works part
time at the local pharmacy as a retail assistant. She also plays competitive netball on Saturday
afternoons and has come to you for advice on what to eat pre-game as she has been getting tired
during the game. Most weeks the game times are fixed. On those days, approximately three hours
before the game, Lihua has a pre-game meal at home of noodles (½ cup) with tofu (170g) and
vegetables (1 cup cooked broccoli) and drinks 250mL of water. However, for weekends when the
game times are not fixed, Lihua does not eat before leaving home because she does not want to risk
playing on a full stomach. Lihua is vegetarian, she does not include dairy in her diet but does
consume eggs.
Case Study Questions
1. Estimate the total amount (grams and kilojoules) each of the macronutrients in the pregame meal provides.
2. Approximately how much carbohydrate is recommended for consumption before exercise
sessions lasting more than 60 minutes?
Written Response:
Using the information provided and your calculations, provide recommendations for Lihua,
considering the following:
1. What advice would you give Lihua regarding her current pre-game meal? Would you provide
any adjustments to this meal? If so, provide a suggested pre-game meal that may help
optimise her performance.
2. What dietary strategies do you suggest for Lihua regarding days that the game timetable is
3. What advice would you give her regarding her fluid consumption before the game?
