Protein intake risk matrix
Intake level, pattern persistence, recent decline, and clinical context
The current case occupies a risk cell defined by weight-normalized intake and low-day persistence; directional markers add recent decline and contextual prompts.
Screening signal register
Independent intake signals and follow-up actions
The thresholds organize questions; they are not validated diagnostic cutoffs.
| Signal | Current value | Educational trigger | Points | Interpretation | Follow-up |
|---|
Screening setup
Use a representative week and preserve clinical context
- Enter a seven-day average rather than one day.
- Use the same tracking method for the prior comparison.
- Count days below a chosen minimum.
- Record unintentional weight change separately.
- Mark known health conditions so the tool directs—not replaces—professional guidance.
Pattern-risk logic
Low intake, sudden decline, and medical context are different signals
A modest average may be stable and intentional, while a sharp decline with unintentional weight loss asks a different question. The matrix separates level from persistence and direction.
The score is educational and not a validated malnutrition screen. It should never delay clinical assessment when appetite loss, weakness, illness, or substantial weight change is present.
Calculation method
Score distinct intake-pattern prompts without diagnosing deficiency
Weight-normalized intake, change from prior average, persistence of low days, meal distribution, unintentional weight loss, age context, and a known clinical flag contribute separate points.

Follow-up triage
Four signals that should not be collapsed into grams per day
The page distinguishes intake level, recent change, repeated low days, and clinical context.
Weight-normalized level
—Current average relative to entered weight.
Direction
—Percent change from the prior average.
Persistence
—Weekly share of low-intake days.
Follow-up category
—Educational priority after all prompts.
Decision takeaway: A known medical condition or unintentional decline should move the next step toward qualified assessment, not a self-prescribed target.
Escalation review
Symptoms and contexts that need professional attention
- Unintentional weight loss
- Persistent poor appetite
- Swallowing or gastrointestinal difficulty
- Weakness or functional decline
- Kidney, liver, metabolic, or other clinical disease
Screening evidence
Information to take to a clinician or dietitian
- Seven-day intake record
- Prior and current weights
- Appetite and symptom timeline
- Medication and diagnosis list
- Functional and activity changes
Practical applications
Decisions this calculator is designed to support
Stable low-looking average
A small adult reports a stable average with no weight loss and few low days.
What the result clarifies: Weight normalization and persistence prevent an automatic high-priority label.
Abrupt decline with weight loss
Average intake has fallen sharply and weight loss was unintentional.
What the result clarifies: Direction and clinical context raise follow-up priority beyond the grams-per-day value.
Worked example
Current-input substitution and reconciliation
Model limitations
This calculator is not a validated malnutrition, kidney, or disease screening instrument and cannot determine an appropriate intake. Known disease, unintentional weight loss, appetite loss, swallowing problems, weakness, or other concerning symptoms require qualified healthcare assessment.
Protein Intake Risk Screening Calculator | Intake Context Flags FAQ
Does the score diagnose low protein?
No. It organizes educational prompts from entered data.
Why include prior intake?
A sudden decline may matter even when the current absolute value is not extreme.
What does the clinical flag do?
It prioritizes professional guidance because general targets may not apply.
Can I use the score to choose supplements?
No. Product and intake decisions should follow appropriate dietary and clinical assessment.
