- Fat Mass (%): The percentage of fat in your body.
- Water Percentage (%): The percentage of water in your body.
- Skeletal Muscle Percentage (%): The percentage of skeletal muscle in your body.
- Basal Metabolic Rate (BMR): The number of calories your body needs to perform basic, life-sustaining functions.
- Body Mass Index (BMI): A measure that uses your height and weight to work out if your weight is healthy.
Refer to the "Laica Home Wellness" app for detailed explanations of these metrics and personalized insights.
