Calorie Deficit Formula:
| From: | To: |
The Calorie Deficit Calculator estimates the difference between your Total Daily Energy Expenditure (TDEE) and your daily calorie intake. This deficit is essential for weight loss, as it represents the energy shortfall that prompts your body to use stored fat for fuel.
The calculator uses the Calorie Deficit formula:
Where:
Explanation: The equation calculates the energy deficit by subtracting your daily calorie consumption from your total energy needs. A consistent deficit leads to weight loss over time.
Details: Calculating calorie deficit is crucial for effective weight management. It helps create a sustainable weight loss plan, ensures you're not under-eating or over-eating, and provides a scientific approach to fat loss.
Tips: Enter your TDEE in kcal/day and your daily calorie intake in kcal/day. Both values must be positive numbers. The calculator will show your daily calorie deficit.
Q1: What is a healthy calorie deficit for weight loss?
A: A deficit of 500-1000 kcal/day is generally recommended, leading to 1-2 pounds of weight loss per week.
Q2: How do I calculate my TDEE?
A: TDEE can be estimated using formulas that consider your BMR (Basal Metabolic Rate) and activity level, or through metabolic testing.
Q3: Is a larger calorie deficit better for faster weight loss?
A: While larger deficits may lead to faster weight loss initially, extremely large deficits can be unsustainable and may lead to muscle loss and metabolic adaptation.
Q4: Should I adjust my calorie deficit over time?
A: Yes, as you lose weight, your TDEE decreases, so you may need to recalculate and adjust your deficit periodically.
Q5: Can I use this calculator for weight gain?
A: For weight gain, you would aim for a calorie surplus (positive value) instead of a deficit.
