Why Use a Smart Scale?
Traditional scales only measure total body weight.
A smart scale uses Bioelectrical Impedance Analysis (BIA) technology to estimate body composition metrics such as:
- Body fat percentage
- Muscle mass
- Bone mass
- Water percentage
- BMI
- Basal metabolic rate (BMR)
- Visceral fat
These insights provide a much clearer picture of your health and fitness progress.
Are Smart Scales Accurate?
Smart scales are generally accurate for tracking long-term trends, but they should not be considered medical-grade devices.
Factors that can affect readings include:
- Hydration levels
- Meal timing
- Exercise
- Time of day
The most important thing is consistency. Use your scale at the same time each day under similar conditions.
