Hume Scale Review at 71: It Says My Metabolic Age Is 53

I get on a scale once a week. Most people do it to check one number. I do it to check about a dozen.

This is my Hume scale review after using it daily in my 200 Year Life Project. The Hume Body Pod is a smart scale that runs a bioelectrical impedance scan every time I step on it — weight, body fat percentage, lean mass by body segment, visceral fat, hydration, and the number everybody asks me about: metabolic age.

My Hume scale says my metabolic age is 53.

I'm 71 years old.

Wait — Didn't Your Blood Test Say 56?

Sharp eye. If you read my CardioSmile review, you saw that my Function Health blood work puts my biological age at 56. Now the scale says 53. So which is it?

Honest answer: both, and neither. They're measuring completely different things.

Function Health draws my blood twice a year and runs it through more than 100 biomarkers — lipids, hormones, inflammation, kidney and liver function. Their biological age number comes from what's happening inside my body chemistry.

The Hume scale never touches my blood. It sends a tiny electrical signal through my body and calculates metabolic age from body composition — how much of me is muscle, how much is fat, and where it sits. A 71-year-old carrying the lean mass and fat percentage of a 53-year-old gets a 53.

Two different rulers. Two different numbers. One direction: down. That's the only part I actually care about. Every number I track is public on my Blood Test Results page.

What the Hume Scale Tracks

This morning it read 184.0 pounds. But the weight is the least interesting part. The app breaks my body into segments — arms, legs, trunk — and shows fat and lean mass for each one. My trunk carries 78.4 pounds of lean mass. My right arm is 10.2% fat. I know these numbers the way I used to know batting averages.

Why does that matter at 71? Because muscle is the retirement account of aging. Sarcopenia — age-related muscle loss — is one of the biggest predictors of frailty, falls, and decline. I can't fight what I can't measure. The Hume scale turns “I think I'm getting stronger” into a chart.

How I Use It

Same time in the morning once a week. After the bathroom, before coffee, minimal clothing. Consistency matters more than precision with any bioimpedance scale — hydration swings the readings, so I control everything I can and watch the trend line, not the daily number.

Thirty seconds on the scale, and the app has already synced before I'm done brushing my teeth (with this, naturally).

The Bottom Line

Is a $200-class smart scale as accurate as a DEXA scan? No. Is it 1,000 times more useful than a dumb scale? Yes.

I'm 71 chronologically, 56 by my blood, and 53 by my body composition. Every one of those numbers is heading the right way, and this scale is how I catch it when they're not.
