Daily Calorie Expenditure Calculator
Here’s a comprehensive table summarizing all you need to know about Daily Calorie Expenditure:
| Aspect | Description |
|---|---|
| Definition | Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a day, including basic functions and physical activity4. |
| Components | 1. Basal Metabolic Rate (BMR) 2. Physical Activity 3. Thermic Effect of Food (TEF) 4. Non-exercise Activity Thermogenesis (NEAT)4 |
| BMR | Calories needed for basic bodily functions (e.g., breathing, cell production, blood circulation)3. |
| TDEE Calculation | TDEE = BMR × Activity Factor1 |
| Activity Factors | Sedentary: 1.2 Light Exercise (1-2 days/week): 1.375 Moderate (3-5 days/week): 1.55 Heavy (6-7 days/week): 1.725 Athlete (2x/day): 1.9+1 |
| Factors Affecting TDEE | Age, sex, weight, height, activity level, body composition, thermogenesis, pregnancy/breastfeeding2 |
| Weight Loss | Create a calorie deficit by consuming fewer calories than your TDEE4. |
| Weight Gain | Consume more calories than your TDEE1. |
| Maintenance | Consume calories equal to your TDEE1. |
| Accuracy | TDEE calculators provide estimates; individual results may vary4. |
| Adjustments | Re-evaluate TDEE periodically as it can change over time due to various factors4. |
| Tracking | Use apps or online tools to track calorie intake and expenditure3. |
| Recommendation | When in doubt, underestimate activity levels and overestimate food consumption for weight loss3. |
This table provides a concise overview of the key aspects of Daily Calorie Expenditure, including its definition, components, calculation methods, factors affecting it, and how to use this information for weight management. Remember that while these calculations provide useful estimates, individual results may vary, and it’s always best to consult with a healthcare professional or registered dietitian for personalized advice.
