What Body By Numbers is
See where you stand.Track how you improve.
Body By Numbers is a health tool. Type in a few numbers from a recent blood test, plus your blood pressure, height and weight. You get:
- A grade, A+ to F, for blood pressure, cholesterol, blood sugar and body weight
- One overall grade for your health
- Your Biological Age
- What to work on first, with simple steps


Real screens from the product. Sample data, not a real person.
How you use it
Measure. Change. Measure again.
Body By Numbers is not a one-time report. It is a loop you run a few times a year, and your grade is how you keep score.

FAQ
Questions, answered.
What people ask before their first grade.
No. The free grade runs on what you already know: your height, your weight, and a recent blood pressure reading, and it gives you one overall grade. Lab numbers are what a full report adds, because cholesterol and blood sugar are two of the four things we grade, and a full report grades each of them on its own. Start free, and get a full report once your lab results are in.
Any standard blood panel will do. The usual routes are your next physical, a lab your doctor sends you to, or a walk-in lab you book yourself. What you want is a lipid panel and a fasting glucose; an HbA1c is a helpful extra. We do not run the draw or sell the test. You bring the numbers, we grade them.
Each number is scored against what the research says is optimal, rather than against the wide “normal” band on a lab printout, which only tells you that you are not sick yet. Those scores become letter grades for body composition, blood pressure, cholesterol and blood sugar, and those four roll up into one overall grade. The same formulas apply to everyone, adjusted only for age and sex.
It is an estimate from your numbers, worked out from the same markers you entered, and it is always shown next to your actual age. Two years younger means your numbers look like those of someone two years younger than you. It is worked out again from your numbers each time you make a report, so a new report shows where it stands now.
Free is the preview: one overall grade from numbers you already have, with no bloodwork and no account. Snapshot is one full report from real lab results, yours to keep, for $39. Membership is $99 a year. It is a year of the full grading system: retest whenever there are new numbers, up to once a month. Each new report sits beside the last in Trends. If you upgrade within 30 days, what you paid for Snapshot comes off your first year.
No, and we tell you before you commit. A report is final once it is created, which is why the last step shows every number back to you to check. If a wrong number does get through, the fix is a new report rather than an edit to the old one. On Membership that costs nothing extra: your next report opens 30 days after the last one.
Your grades, not your numbers. Everything you type is graded and then discarded, so the cholesterol figure you entered never reaches our database. What we keep is the result: your letter grades, your scores and your Biological Age. None of it is ever sold.
Purchases are not refundable, for Snapshot or Membership. Membership runs for a year and renews at the end of it. You can cancel at any time, and cancelling stops the next renewal.
No. Body By Numbers is a wellness product. It grades numbers you already have and points you at the one worth working on first. It is not medical advice. If a grade worries you, that is exactly the thing to take to your doctor, and the report is built to be easy to hand over.
Body By Numbers was created by Jeffrey Blue, MD, a family and sports physician in practice since 1998. He built it so anyone can see their everyday health numbers clearly, and take them to their own doctor.
Why not just go by "normal"?
Normal on a lab report only means you are not sick. We grade against what healthy actually looks like.
