Setting custom DRVs

6th Jan 2018

Nutritics allows you to set custom Dietary Reference Values which will be displayed visually on the report. This ‘power feature’ allows you to set nutrient targets as precise intakes, as calculations based on body weight (or other formula based targets) or as an acceptable distribution range. You can also define lower and upper limits for any nutrient.


The DRV editor can be accessed from Menu>Settings>Preferences  or by selecting  ‘Custom DRV…’ from the DRV source drop down options (on the client set up, reports and meal plans) 


This will open the following screen: 

Creating a New Entry:

1. Click the Custom DRV button from the drop down in the client section
2. Name the DRV and provide a reference or author and description if desired.
3. Click the 'duplicate this DRV' button
4. Define the inclusion criteria that the DRV’s will apply to (gender, age range etc)
5. Define the DRV’s using the guide below
6. Changes are saved automatically

Editing an Existing Entry:

1. Select the DRV source you wish to edit from the drop down at the top left (The field “Nutritics” in the example above)
2. Click the 'Duplicate this DRV...' button
3. Rename the DRV, author, and description as desired.
4. Select the record you wish to edit from the drop down at the top right (The field “Select Record” in the example above”). This will import the existing values into the tables which can now be edited.
5. Changes are saved automatically


Basic Programming:

Type any figure in the box to set that figure as the Recommended Intake:

Add a ^ symbol (shift + 6) after the recommendation to include a lower limit.

Add a second ^ to include an upper limit:

Use a | symbol (shift + )to set a recommended intake range:

Advanced Programming:

Use basic calculator notation (addition +, multiplication *, subtraction -, division /) and nutrient keywords to program advanced formulae.  

Acceptable keywords include weight, age, bodyfat, lbm (lean body mass), bmi, eer (recommended kcal intake) and pal. These are based on data from the client information panel (panels 2 and 3). Take note they are all lower case.

You can also use any nutrient in a formula by typing it in the box exactly as it appears in the DRV editor (all lower case).

Working Examples:

1. Carbohydrate intake is 55% of kcal intake

EER is estimated energy requirements, multiplication by .55 gives 55%. 3.75 is the number of calories in one gram of carbohydrate, this converts the 55% of calories into a weight in grams


2. Carbohydrate intake is 55% of kcal intake with a lower limit of 100g


3. Carbohydrate intake is 55% of kcal intake with a lower limit of 100g and an upper limit of 75% of calorie intake


4. Protein intake is 20% of kcal intake 

4 is the number of calories per gram of protein, this converts 20% of calories to grams. 


5. Protein intake is 1.2 times the client’s body weight


6. Protein intake is a range from .8 -1.6 times the client’s body weight


7. Fat intake is a range from 20-35% of kcal intake

9 is the number of calories per gram of fat


8. Fat intake is a range from 20-35% of kcal intake and an upper limit of 40% of kcals. 


9. Folate intake is a range 300-600µg with a lower limit of 100 µg and an upper limit of 1000 µg


10. Vitamin D intake is 15µg with a lower limit of 5 µg
