The number of calories you burn daily depends on several factors including your age, sex, height, weight, and activity level. There's no single answer, but we can provide estimates.
Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE)
Your body burns calories even at rest, maintaining basic functions like breathing and heartbeat. This is your Basal Metabolic Rate (BMR). Your Total Daily Energy Expenditure (TDEE) includes your BMR plus calories burned through physical activity and digestion.

Estimates for BMR (without activity): A commonly cited range is approximately 2,000 to 2,450 calories for men and 1,600 to 1,950 for women. These are just estimates, and individual needs vary significantly. [Source: Multiple sources including WebMD and Healthline articles cited in references]

Factors affecting TDEE: Several online calculators (like this one) can help estimate your TDEE by considering your age, sex, height, weight, and activity level. Your TDEE is a more accurate reflection of your total daily calorie expenditure. [Source: Verywellfit, TDEE Calculator links in references]
Activity Level and Calorie Burn
Your activity level significantly impacts your daily calorie burn. A sedentary lifestyle will result in a lower TDEE compared to a highly active one. Even small increases in activity can make a difference.

Weight Maintenance: To maintain your current weight, aim for a balanced calorie intake that matches your TDEE. [Source: Autonomous.ai blog post in references]

Weight Loss: Creating a calorie deficit (burning more calories than you consume) is crucial for weight loss. [Source: Multiple sources, including Southern California health article]
Using Calorie Calculators and Tracking Tools
Many online tools and apps can help you estimate your daily calorie needs and track your intake and expenditure. Remember these are estimates, and individual results vary.
