Assessment workspaceBodyMetrics Assessment
Body measurements, energy needs and daily rhythm. Every section is optional.
Prepare the report
First and last names are optional. The report can also remain anonymous.
The report includes available results, explanations and CircaTest recommendations once all 19 questions are complete. In the next dialog, choose a printer or save as PDF.
The name, profile, measurements, settings and CircaTest answers will be cleared.
Measurements & body frame
Enter only the measurements relevant to the assessment.
Weight and height for BMI; sex and height for body frame.
These two measurements are optional when checking BMI.
How to measure waist circumference
Stand upright and measure at navel level after a normal exhalation.
Use the same measurement point for future assessments.How to measure elbow breadth
With the elbow bent to approximately 45°, use a sliding caliper to measure the distance between the two bony prominences. Enter the breadth in millimeters.
Ideally, repeat the measurement 2 to 3 times and use the average.Enter weight and height in the profile.
Enter elbow breadth to estimate body frame.
Understanding body frame
The thresholds used appear after sex, height and elbow breadth have been entered.
This estimate describes body frame; it does not determine athletic ability.BMI does not distinguish fat mass from muscle mass.
BodyFat Blueprint
Choose a protocol, then enter the skinfold measurements.
Body weight is used to calculate fat and lean mass in kg. Body-fat percentage can be estimated without it.
Measurement guidance
Enter body weight to convert the body-fat estimate into kilograms.
Understanding fat and lean mass
Fat mass is calculated from body weight and the estimated body-fat percentage. Lean mass is the remaining weight: it includes more than just muscle.
Estimate based on the selected protocol. Use the same protocol when comparing measurements.
EnergyScope Tracker
For ages 19–78. Complete the profile, then select an activity level and a goal.
No skinfold or waist measurement is required.
Which factors are used?
Sedentary: × 1.35 · Active: × 1.55 · Vigorous: × 1.75.
These three factors are practical approximations of daily activity. They are not part of the Mifflin–St Jeor equation.Mifflin–St Jeor estimates resting energy expenditure. Daily expenditure and target intake remain estimates to adjust based on actual progress.
Method and limitations
The original study included adults aged 19 to 78. EnergyScope uses this age range; it does not guarantee accuracy for every individual.
Maintenance: estimated expenditure. Deficit: −15%. Surplus: +10%. These are starting estimates to adjust to individual needs.
No automatic target is provided at 1,200 kcal/day or below, and no deficit is proposed for a BMI below 18.5. These are limits of the tool, not universal nutritional safety thresholds.

CircaTest · 19 questions
19 questions to explore the person’s natural daily rhythm.
No body measurements are needed. The questionnaire is optional.
Answer for yourself or the person being assessed. Imagine a schedule with no external commitments and focus on natural preferences.
The result remains available when switching between sections.
Answers are kept while other sections are being viewed.
How to answer
Choose the answer that best reflects natural preferences. Select “Confirm and continue” to move on, or “Previous” to review an earlier answer.
This adapted 19-question assessment suggests a daily rhythm tendency to consider alongside everyday life. It is not a standardized version of the Morningness–Eveningness Questionnaire (MEQ).Clear the CircaTest answers? Body measurements will be kept.
The result will appear after all 19 questions.
Answers to this questionnaire do not change body or energy calculations.
Daily timing suggestions
Use these suggestions as a starting point. Adjust them to suit daily commitments and how the person feels.
