Diet analysis assignment food log and NutriCalc guide
Keep a detailed three-day food diary on the supplied record form, enter it into the NutriCalc program under weight maintenance with an accurate activity level, and produce the Bar Graph, Calorie Assessment and MyPlate reports that the rest of the project depends on.

Get the data right, because Parts 1 and 2 rest on it
This is the first of three parts and everything later inherits it, so treat accuracy as the assignment rather than as diligence. The brief is unusually specific about configuration and each instruction has a reason. Use NutriCalc rather than another tracker, because the later parts need reports those apps do not generate, and the brief states plainly that work done in other software will not receive credit. Use the provided food record form rather than the one inside the program. Choose three consecutive days, two weekdays and one weekend day, and choose typical ones: recording on a birthday, during illness, or on a day the cupboards were empty produces an analysis of an unusual week rather than of your diet. Record immediately after eating rather than at the end of the day, because recall shrinks portions and drops whatever was eaten without thinking. Carry the form with you: a diary written from memory in the evening is a different document.
Portion size is where the error lives, which is why the brief flags it twice. The tools in chapters 1 and 2 exist to convert what is on the plate into something the program can price, and fifteen French fries entered as fifteen servings of French fries is the brief's own illustration of how far one slip travels. Set the profile to weight maintenance rather than weight loss: if weight change is a goal you discuss it in the paper, but the analysis is of the diet you actually have. Be honest about activity level, since overestimating it raises every reference value and makes an inadequate intake look adequate. Then apply the plausibility check the brief hands you, where intakes above 2,500 calories for women or 3,500 for men, or below 1,500 for anyone, are more likely to be entry errors than facts. Save all three reports as PDFs before the deadline rather than after it.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Record dietary intake with the detail required for accurate analysis.
- 02Recognise portion estimation as the main source of error in food records.
- 03Select representative days rather than convenient ones.
- 04Configure dietary analysis software so its reference values are correct.
- 05Identify implausible intake totals before submitting an analysis.
Read the full question
Review every instruction before using the planning guidance that follows.
Turn the brief into deliverables
- 01A three-day food diary covering two weekdays and one weekend day.
- 02The record kept on the provided food record form, not the program's own.
- 03A NutriCalc profile set to weight maintenance with an accurate activity level.
- 04All food and beverage entered, with recipes checked against the MyPlate report.
- 05The Bar Graph, Calorie Assessment and MyPlate reports saved as PDFs.
Choosing days, recording, entering, reporting
Choosing the three days
Select consecutive, representative days and justify the choice.
Recording in the moment
Set out the discipline of recording immediately and in detail.
Portion accuracy
Explain estimation techniques and why they dominate the error.
Setting up NutriCalc
Configure profile, weight maintenance and activity level correctly.
Checking before you report
Apply the plausibility checks the brief supplies and produce the reports.
What accurate dietary assessment requires
Recommended databases
- MedlinePlus
- StatPearls via NCBI Bookshelf
- NutritionCalc Plus documentation
- Your course textbook chapters 1 and 2
- PubMed
Search sequence
- 1.Read chapters 1 and 2 for the portion estimation tools the brief refers to.
- 2.Watch the NutriCalc tutorial before creating the profile.
- 3.Check what counts as each activity level, and locate yourself honestly.
- 4.Read a reference on dietary assessment error before judging your totals.
- 5.Verify each of the three reports exists before the deadline.

These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.

Review before submission
Common mistakes
- Using another tracking app, which the brief says will not receive credit.
- Choosing atypical days such as a birthday or a day of illness.
- Setting the profile to weight loss when the brief says maintenance.
- Overestimating activity level, which inflates every reference value.
- Recording supplements and fortified drinks, which the brief excludes.
- Confusing fifteen French fries with fifteen servings of French fries.
Submission checklist
- Three consecutive days are covered, including one weekend day.
- Each entry records meal, time, portion, location, company and activity.
- Hunger rating, mood and eating duration are recorded.
- The profile is set to weight maintenance.
- Total intake is plausible for your sex and activity level.
- All three required reports are saved and submitted.
