A local, educational LE8-style calculator. Nothing is stored here, and the score is not a diagnosis or treatment plan.
BMI is an imperfect screening signal and does not measure muscle, body composition, or health by itself.
These inputs create a secondary exploratory estimate after at least 6 domains are entered. The raw Vital8 score above remains unchanged.
Strengths will appear here as more domains reach 80 or higher.
These are the entered areas most likely to move the foundation if you focus on them first.
Enter a few domains and the highest-ROI levers will appear here.
Do not try to overhaul everything this week. Pick one behavior, one measurement, and one follow-up step.
Walk 25 minutes after dinner 5 days per week.
Check home blood pressure for 7 days.
Ask about fasting lipids, hemoglobin A1c, ApoB, and Lp(a).
This creates a concise text summary of your score, strongest domains, highest-ROI levers, and next steps. Only share health information where you are comfortable with the privacy of that app or conversation.
