What Are Daily Calorie Needs?
Your daily calorie needs refer to the number of calories your body requires to function properly throughout the day, including basic functions like breathing, digestion, and physical activity.
This number varies from person to person depending on factors like age, weight, height, and activity level.

- Weight loss: subtract 300–500 calories
- Maintenance: stay at your calculated number
- Muscle gain: add 300–500 calories
