Calculate Your Daily Calorie Needs
Calorie Goals by Activity Level
| Activity Level | Description | Multiplier | Example Daily Calories |
|---|---|---|---|
| Sedentary | Little/no exercise, desk job | BMR × 1.2 | 1800-2000 cal |
| Light Activity | Light exercise 1-3 days/week | BMR × 1.375 | 2000-2200 cal |
| Moderate Activity | Moderate exercise 3-5 days/week | BMR × 1.55 | 2200-2400 cal |
| Active | Hard exercise 6-7 days/week | BMR × 1.725 | 2400-2600 cal |
| Very Active | Very hard exercise, physical job | BMR × 1.9 | 2600-3000 cal |
Weight Management Guidelines
| Goal | Calorie Adjustment | Expected Rate | Recommendations |
|---|---|---|---|
| Weight Loss (Moderate) | -500 cal/day | 1 lb/week | Safe and sustainable |
| Weight Loss (Aggressive) | -1000 cal/day | 2 lbs/week | Short-term only |
| Maintenance | TDEE | Stable weight | Balanced approach |
| Weight Gain (Lean) | +300-500 cal/day | 0.5-1 lb/week | Minimize fat gain |
| Weight Gain (Bulk) | +500-1000 cal/day | 1-2 lbs/week | Faster muscle gain |

About Daily Calorie Needs
Your daily calorie needs depend on your Basal Metabolic Rate (BMR) and your activity level. BMR represents the calories your body needs for basic functions, while Total Daily Energy Expenditure (TDEE) includes calories burned through physical activity.
Calorie Calculation Methods
- Mifflin-St Jeor (Men): BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age + 5
- Mifflin-St Jeor (Women): BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age - 161
- TDEE: BMR × Activity Level Multiplier
Macronutrient Distribution
- Protein: 25-30% of total calories (4 cal/gram)
- Carbohydrates: 45-50% of total calories (4 cal/gram)
- Fats: 20-25% of total calories (9 cal/gram)
Weight Management Tips
- Create a moderate calorie deficit (500 cal/day) for sustainable weight loss
- Never eat below your BMR for extended periods
- Combine calorie control with regular exercise for best results
- Track your progress and adjust calories as needed
- Focus on nutrient-dense foods for optimal health
Frequently Asked Questions
How many calories do I need per day?
Daily calorie needs vary based on age, gender, height, weight, and activity level. Use our calculator to get personalized recommendations for weight loss, maintenance, or gain.
What is TDEE?
TDEE (Total Daily Energy Expenditure) is the total number of calories you burn in a day, including your BMR plus calories burned through physical activity.
How many calories to lose weight?
To lose 1 pound per week, create a deficit of 500 calories per day below your TDEE. For 2 pounds per week, create a 1000 calorie deficit.
Should I eat below my BMR?
Generally, it's not recommended to eat significantly below your BMR for extended periods as this can slow metabolism and cause muscle loss. Aim to eat between BMR and TDEE for sustainable results.
