What Do BMR and TDEE Mean?
- BMR (Basal Metabolic Rate): The number of calories your body needs to maintain basic life functions at rest. Think of it as your body's "idling" speed.
- TDEE (Total Daily Energy Expenditure): The total calories you burn in a day, accounting for your BMR and physical activity. This is the key metric for weight management.
- Privacy Choice: Unlike many health apps, we do not track or store your measurements. Your health data stays on your device.
