Myth-busting
5 things your smart scale gets wrong about your body
The short version
- It can't see where your weight sits
- Hydration swings it by up to 2kg
- Its body-fat % is a rough guess
- It punishes muscle gain
- It gives you a number, not a decision
It can't see where your weight sits
Two people, same weight, completely different bodies. A scale reads mass — not muscle, not fat, not shape.
Hydration swings it by up to 2kg
Drink water, sauna, salty meal — the number moves. Your body didn't change. Your water did.
Its body-fat % is a rough guess
BIA scales send a current through your feet and estimate. Foot calluses, hydration and meal timing all skew it.
It punishes muscle gain
Building muscle while losing fat can mean the scale doesn't move at all — while your body visibly changes.
It gives you a number, not a decision
Even a perfect number doesn't tell you what to DO today. That's the part that actually changes your body.
