Calorie Deficit Formula:
| From: | To: |
The Calorie Deficit Calculator helps determine the difference between your Total Daily Energy Expenditure (TDEE) and your actual calorie intake. This calculation is essential for weight management, as a consistent calorie deficit leads to weight loss.
The calculator uses the simple formula:
Where:
Explanation: TDEE represents the total number of calories your body burns in a day, including basal metabolic rate and physical activity. Subtracting your actual calorie intake from TDEE gives your daily calorie deficit.
Details: Understanding your calorie deficit is crucial for effective weight management. A sustained daily deficit of 500-1000 calories typically results in a safe weight loss of 1-2 pounds per week.
Tips: Enter your TDEE and daily calorie intake in kcal/day. Both values must be positive numbers. The calculator will show your daily calorie deficit, which indicates how many fewer calories you're consuming than burning.
Q1: What is a healthy calorie deficit for weight loss?
A: A deficit of 500-1000 calories per day is generally recommended for safe and sustainable weight loss of 1-2 pounds per week.
Q2: How do I calculate my TDEE?
A: TDEE can be estimated using online calculators that consider your age, gender, weight, height, and activity level, or measured through professional metabolic testing.
Q3: Can calorie deficit be too large?
A: Yes, excessively large deficits can lead to muscle loss, nutrient deficiencies, metabolic adaptation, and are generally unsustainable long-term.
Q4: Should I aim for the same deficit every day?
A: While consistency is important, some variation is normal. Focus on maintaining an average weekly deficit rather than daily perfection.
Q5: How often should I recalculate my calorie needs?
A: Reassess your TDEE every 4-6 weeks or after significant weight changes (5-10 pounds) as your metabolic needs will change with your weight.
