Energy balance is dynamic
Body weight is influenced by energy intake and energy expenditure, but real changes are not perfectly predicted by a fixed “3,500 calories equals one pound” rule. Metabolism and behavior adapt over time. CalorieBank therefore treats account values as an awareness and decision-support model, not a guaranteed weight-loss calculation.
Nutrition Score uses reference values
Estimated nutrient coverage is compared with age- and sex-based reference values such as Recommended Dietary Allowances and Adequate Intakes when available. Individual needs can differ. Food databases, portion estimates and preparation methods also introduce uncertainty.
A low estimated value is not a diagnosed deficiency. Supplements should be recorded only after they are actually taken, and significant dietary or medical concerns should be discussed with a qualified healthcare professional.
Body metrics require interpretation
BMI is a screening measure based on weight relative to height. It does not directly distinguish fat, muscle and bone. Body-fat, lean-mass, blood-oxygen and cardio-fitness values may vary by device, algorithm, hydration, fit and measurement conditions. Repeated measurements from the same source are generally more useful than one isolated reading.
Apple Health and device data
CalorieBank can read authorized data from Apple Health, including compatible wearable, iPhone, workout-app and smart-scale sources. Missing information remains unavailable rather than being invented. Workout Route displays route data already stored with a compatible workout; it does not begin a new live GPS recording.
