Biyo Body Composition Scanner

Your belly has been growing for years. You eat reasonably. You stay active. But the number on the scale keeps creeping up and you have no idea why.

Your doctor checks your cholesterol, your blood sugar, your blood pressure. He tells you to lose weight. But he never tells you what you are actually losing. Is it fat? Is it muscle? Is the weight around your organs or under your skin? He does not know. His scale does not measure that. Neither does yours.

Most men over 50 lose 3-5% of their muscle mass every decade. That means the weight you are gaining is not just fat. You are replacing muscle with fat and your bathroom scale shows the same number. You think nothing has changed. Everything has changed.

The Gap Your Doctor Left

Your annual physical checks around 20 blood markers. That is useful. But it tells you nothing about what is happening inside your body structurally.

Body composition is the breakdown of what your body is actually made of: how much is fat, how much is muscle, how much is bone, how much is water. Two men can weigh exactly 185 pounds. One has 18% body fat and strong muscle mass. The other has 32% body fat and is losing muscle. Their bathroom scales show the same number. Their health outlook is completely different.

The metric that matters most after 50 is visceral fat. This is not the fat you can pinch. It is the fat wrapped around your liver, kidneys, and intestines. It is the fat your doctor mentions when he talks about heart disease risk and Type 2 diabetes. But he gives you no number. No measurement. No way to track whether it is getting better or worse.

Until now.

What Biyo Actually Measures

Metric 01
Visceral Fat Level
The fat around your organs. The one linked to heart disease and Type 2 diabetes. Your bathroom scale cannot see it. Biyo measures it directly.
Metric 02
Skeletal Muscle Mass
How much functional muscle you actually have. Not just total weight. This is what you are losing every decade after 50, and your doctor is not tracking it.
Metric 03
Body Fat Percentage
Clinically measured using 8-electrode bioelectrical impedance. Not estimated from your height and weight like a BMI chart.
Metric 04
Basal Metabolic Rate
How many calories your body actually burns at rest. This number drops as you lose muscle. If you do not know it, every diet is a guess.
Plus 50 additional metrics: bone mineral content, hydration levels, protein mass, subcutaneous fat, biological age, and more. 54 measurements total. From one scan. In 15 seconds.

98% as Accurate as a DEXA Scan.
Without the Radiation or the Appointment.

Most smart scales use 4 electrodes and only measure your lower body, estimating the rest. Biyo uses 8 electrodes across your hands and feet to scan your arms, legs, and torso directly.
