TRANSCRIPT
Diabetes Queensland is a member-based, non-profit
organisation.
We aim to improve the lives of people affected by all types
of diabetes and those at risk, through advocacy, support
and education in partnership with the Queensland
community.
DIABETES QUEENSLAND
We will:
• Examine the factors affecting carbohydrate counting
from a whole diet perspective;
• Identify the effects of different dietary patterns on
carbohydrate counting;
• Discuss the importance of diet quality in addition to
carbohydrate counting; and
• Understand the challenges of carbohydrate counting
OBJECTIVES
WHO SHOULD CARB COUNT?
Pre-diabetes – maybe for weight loss
Type 1 diabetes – yes
Type 2 diabetes – maybe for weight loss;
generally depends on meds
Gestational diabetes – depends on meds
• Health literacy & numeracy
• Time & motivation
• Taking insulin &
• desires carb flexibility
• able to adjust insulin
• Or taking sulfonylureas
REQUIREMENTS

Insulin adjust insulin to match carbs
Sulfs ensure an even distribution and
consistent intake of carbs
MEDS
Safety – reduce likelihood of hypoglycaemic events
Flexibility – allows carbs to be interchanged (sulfs/insulin)
– allows variable carb intake (insulin)
Improved
outcomes – intensive blood glucose management reduces
the risk of complications (eye disease 76%,
kidney disease3 50%, nerve disease 60%)

LF/HP
• 30g carbs
• 4g fat
• 40g protein
HF/LP
• 30g carbs
• 35g fat
• 5g proteinSmart, C., Evans, M., O'Connell, S., McElduff, P., Lopez, P., Jones, T., King, B. (2013). Both dietary protein and fat increase
postprandial glucose excursions in children with type 1 diabetes, and the effect is additive. Diabetes Care, 36(12), 3897-

• Need carb recognition first
• 1 exchange of carbohydrate = 15g of carb
• Teach number of exchanges per day based on the ADG &
the client’s needs
• Encourage carbohydrate consistency (amount and timing) ***
• Encourage SMBG & record keeping
• Medical team adjusts medication, with dietitian
recommending adjustments to carbohydrate intake according
to pre & post meal BGLs & MNT

ESTIMATING
Thumb = 1 tablespoon
Tight fist = ½ cup Cupped hand = 1 cup
Thumb tip = 1 teaspoon

Accuracy of hands v. household measures as portion size estimation aids. Journal of Nutritional Science, 5, 11.
Calculate the number of exchanges in these two breakfasts
• Breakfast 1:
2 slices wholegrain toast with avocado and vegemite
+ 150ml of 100% orange juice
+ a piece of fruit
• Breakfast 2:
1 cup muesli
+ 1 cup milk
+ 1 sliced banana
+ milk coffee
ACTIVITY
Increased precision:
• Uses grams, ½ exchanges or ½ portions
Why use advanced carb counting?
• Allows bolus insulin dose to be calculated
• Insulin to carb ratio & correction factors to be used
• Allows for a more flexible eating patterns
ADVANCED CARB COUNTING

0 - 6g Do not count
7 - 11g ½ exchange
12 - 18g 1 exchange
19 - 26g 1½ exchanges
27 - 33g 2 exchanges
34 - 31g 2 ½ exchanges
42 - 48g 3 exchanges
• Ready reckoner/apps
• Nutrition information panels
• Smart meters (e.g. Accu-Chek Aviva Expert, Freestyle InsuLinx)
• Insulin pump bolus wizards with or without wireless glucose monitors
• Calculator
• Scales
• Measuring cups and spoons
• Pen and paper
• Insulin : carb and correction factor (ISF)
TOOLS
Must be able to understand:
• Target BGLs
• Role of carbs
• Action of insulin
• Basal-bolus insulin concept
• Carb counting tools
Must be willing to:
• Carry out pattern management/problem solving
• Regularly SMBG and keep records
CLIENT REQUIREMENTS
Kulkarni, K. D. (2005). Carbohydrate counting: a practical meal-planning option for people with diabetes. Clinical Diabetes, 23(3)
• Education time for dietitian and client
• Labour/time intensive for client
• More advanced health literacy/maths
• More SMBG
• Must have an interest in food & having flexible eating patterns
• Awareness of other factors affecting BGLs e.g. fibre, fat, alcohol,
stress, illness, hormones, individual variation
LIMITATIONS
Kulkarni, K. D. (2005). Carbohydrate counting: a practical meal-planning option for people with diabetes. Clinical Diabetes, 23(3)
• Difficult to be exact – aim for “best estimate” rather than
“guess”
• Better accuracy leads to more predictable BG response
• +/- 10g carb does not have significant affect on BGLs
• SBGM will help to assess accuracy
PRECISION
Calculate the grams of carb:
• Per serve
• Per 100g
Calculate the number of
exchanges:
• Per serve
• Per 100g

• iPhone & Android
Work in teams of 2-3.
Measure out what you would normally serve yourself and
calculate the amount of carb in grams and exchanges for each
food using cups/scales/your hands for measuring.
For calculations, use multiple references
- A food label
- Calorie king book
- DQ carb counting booklet
and compare the results.
PRACTICAL ACTIVITIES
• ‘C’ calories Vs. ‘C’ carbohydrate
• Forgetting to ‘zero’ on the scales
• Ounces vs. grams on the scales
• Raw vs. cooked foods
• Food label: incorrect information, small print, confusion & poor interpretation
• Using the calculator
• Using ‘sugars’ and not ‘total carbohydrate’
• Forgetting to count the extras (e.g. cup of soup, sauces)
• Your serve size isn’t their serve size
STUMBLING BLOCKS
• A meal with minimal carb needs no additional insulin
• However, a small amount of insulin may be required to
“supplement” the basal insulin
• The general idea of a meal containing no carb needs
consideration about balance in food over the day
WHAT ABOUT CARB FREE MEALS?
We‘ve covered:
• Who should carb count and to what level
• How to carb count (and you’ve practiced this!)
• And why we carb count.
