What It Measures in Kaizora
Weight, Fat Mass, Total Muscle Mass, and Bone Mineral Content (the scale’s estimate). The live connection, when it arrives, adds Body Fat Percentage, Fat-Free Mass, a standing Heart Rate, and Pulse Wave Velocity.
- Weight
- Body composition
How It Gets to Kaizora
A file import today: download your data from Withings and import the ZIP. A live connection that syncs every hour is coming, and it updates the same readings instead of adding them twice.
Strengths
- Measures more than a plain body composition scale, including your heart rate and pulse wave velocity, an indicator of how stiff your arteries are.
- Syncs over Wi-Fi and recognizes each person in a household.
Limits
- Body composition is estimated by a current through your feet, so it shifts with hydration and the time of day.
- Its visceral fat index and nerve health score are Withings’ own scales, and they aren’t imported. Neither is body water, yet.
- Heart rate and pulse wave velocity aren’t in Withings’ export, so they wait for the live connection.
About What It Measures
How Accurate Are Smart Scales at Body Fat and Muscle?
How bioelectrical impedance works, what a study of fifteen devices found, why hydration moves your reading, and how to weigh in so the trend means something.
What Does Your BMI Tell You, and What Does It Miss?
The WHO's body mass index categories, the lower cut-offs used for many populations, why BMI can't tell fat from muscle, and how to read your own number over time.
What's a Healthy Body Fat Percentage?
The ranges most often used for adults by sex and age, where they come from, why no guideline sets an official cut-off, and why the method you measure with changes the number.
Why Does Your Weight Change From Day to Day?
Water, glycogen, food in transit, weekends, and the menstrual cycle all move the scale. How big normal swings are, and how to read the trend underneath them.
Why Your Devices Disagree About Your Weight and Your Steps
Two scales give two weights, and your phone and your watch count different steps. Here's why, which number to trust, and how to keep the comparison fair.
