BMR, TDEE, and goal-based calorie targets are automatically calculated.
Glossary
- BMR (Basal Metabolic Rate)
- Calories burned at rest to maintain basic life functions such as heartbeat, breathing, and body temperature.
- TDEE (Total Daily Energy Expenditure)
- BMR multiplied by an activity factor — the total calories you burn in a day.
- Harris-Benedict Equation
- A 1919 formula, revised in 1984, widely used to estimate BMR from body measurements.
- Activity Multiplier
- A factor (1.2–1.9) representing your weekly exercise intensity applied to BMR to get TDEE.
- Caloric Deficit
- Consuming fewer calories than your TDEE — required for weight loss.
- Caloric Surplus
- Consuming more calories than your TDEE — used for muscle gain (bulking).
FAQ
- Q.Is my data sent to a server?
- No. All calculations run locally in your browser.
- Q.How accurate are the results?
- The revised Harris-Benedict formula provides estimates. Actual metabolism varies by muscle mass, body fat, and genetics.
- Q.How do I set a cut (weight loss) calorie target?
- A deficit of ~500 kcal/day below TDEE is commonly used, resulting in ~0.5 kg/week of weight loss.
- Q.Is this suitable for teenagers?
- The formula is designed for adults. Teens should consult a doctor or dietitian.
