Body composition is one of those topics where the methodology matters as much as the result. A bathroom scale, an InBody machine at your gym, a skinfold caliper test, and a DEXA scan can all give you “your body fat percentage” — and produce four different numbers, sometimes ten percentage points apart. If you’re shopping for body composition Vancouver options in 2026, here’s how the methods actually compare, and why we built BodyStats around DEXA.

The five methods you’ll actually encounter in Vancouver

If you walk into different gyms, clinics, and studios across Metro Vancouver, you’ll see five technologies in regular use:

Method	How it works	Accuracy (CV)	Typical cost
DEXA	Dual-energy X-ray	±1.0–1.5%	$29.99–$300
BodPod	Air displacement	±2.7%	$50–$120
Hydrostatic weighing	Underwater weighing	±2.0%	Rare in 2026
InBody / BIA	Electrical impedance	±3.5–5%	Free at gym
Skinfold calipers	Pinch + measure	±3.5% (if expert)	$0–$50

The accuracy column is what matters most. CV (coefficient of variation) is essentially how much the result wobbles between repeat measurements on the same person. Lower is better.

Why “convenient” methods are often the wrong choice

Most people start with whatever’s free or convenient — typically an InBody scale at their gym or a smart scale at home. Both use bioelectrical impedance, which works by passing a tiny current through your body and measuring resistance. The math is straightforward and the readings are fast. The problem is that the result depends heavily on three things you can’t always control:

1. Hydration. A 2% shift in body water can swing a BIA body fat reading by 2–3 percentage points. Drink a litre of water before stepping on, and your reading drops. Don’t drink for eight hours, and it climbs.
2. Recent meals. Eating shifts water and electrolyte balance. Most BIA protocols require a 4-hour fast for accurate readings; people rarely follow this.
3. Time of day. Your hydration changes throughout the day. Morning readings are usually 2–3 points different from evening readings.

If you’re using an InBody to track a 12-week cut and your readings vary by 4% just from when you measured, you can’t tell if you actually lost fat. The signal disappears in the noise.

Not all DEXA scanners are equal — and we use the better one

The DEXA market has two main manufacturers: Hologic and GE Lunar. Both are clinical-grade. They are not equivalent.

Most other Canadian clinics use the GE Lunar iDXA. We use the Hologic Horizon W — generally considered the gold-standard body-composition DEXA in 2026. The Hologic delivers better segmental lean mass precision and a more accurate visceral fat (VAT) estimation than the GE Lunar. The differences aren’t enormous, but for repeat tracking they show up — particularly in the limb-by-limb breakdown.

So when a Toronto or Vancouver competitor charges $300 for what looks like the same scan, you’re often paying more for a slightly less precise scanner. That’s not the marketing story they tell, but it’s the reality of the hardware market.

Why DEXA wins for tracking

DEXA’s coefficient of variation is under 1.5%. That means if we scan the same person twice on the same day, the body fat percentage rarely changes by more than a percentage point. Across an 8–12 week training block, that level of precision is exactly what you need to detect a real 1–2% body fat change.

DEXA also gives you data the other methods can’t:

• Regional breakdown. Fat and lean mass in your left arm, right arm, left leg, right leg, and trunk separately. Critical if you’re rehabbing an asymmetry or training around an injury.
• Visceral fat (VAT). The deep abdominal fat that wraps around your organs. The most clinically meaningful fat for metabolic risk.
• Bone mineral density. Z-scores and T-scores. Essentially a free bone density assessment alongside the body comp report.

What separates a $29.99 BodyStats DEXA from a $300 one

Most DEXA clinics in Vancouver hand you the printed PDF the scanner generates by default. That’s the product. We do something else.

In our honest view: the more you pay for a body-composition DEXA scan, the more you’re paying for clinic overhead — not better data, better tracking, or better insights.

Where to get each method in Vancouver

• DEXA: Our Gastown studio at 316 Carrall Street, $29.99. Other Vancouver clinics offer DEXA at $80–$300 with referral or by appointment.
• BodPod: Available at UBC’s Allan McGavin Sports Medicine Centre and a few other research-affiliated clinics.
• InBody: Most major gyms (Steve Nash, GoodLife, F45) include InBody scans free for members.
• Skinfolds: Most personal trainers and physiotherapists offer skinfold testing.
• Hydrostatic weighing: Increasingly rare. UBC has historically operated a tank.

How to pick what’s right for you

Three rules of thumb:

1. If you just want a number, anything works. An InBody reading is fine for “where am I roughly?”
2. If you’re tracking change over weeks or months, you need DEXA. The other methods can’t reliably detect a 1–2% body fat shift, which is the actual rate of change for a healthy cut.
3. If you’re an athlete or training around an injury, you need DEXA’s regional breakdown. Total body fat percentage isn’t enough.
