1. What is Daily Calorie Deficit?

A daily calorie deficit occurs when you consume fewer calories than your body burns. This energy imbalance forces your body to use stored fat for energy, resulting in weight loss over time.

2. How Does the Calculator Work?

The calculator uses the simple calorie deficit equation:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (calories your body burns per day)
• \( Intake \) — Calories consumed through food and drink
• \( Deficit \) — The calorie shortfall that leads to weight loss

Explanation: A deficit of approximately 500 calories per day typically results in about 1 pound (0.45 kg) of weight loss per week.

3. Importance of Calorie Deficit for Weight Loss

Details: Creating a consistent calorie deficit is the fundamental principle behind weight loss. Understanding your deficit helps you plan appropriate dietary changes and track progress toward your weight loss goals.

4. Using the Calculator

Tips: Enter your TDEE (calculated through other methods or fitness trackers) and your daily calorie intake. Both values should be in kcal/day. The calculator will show your daily calorie deficit.

5. Frequently Asked Questions (FAQ)

Q1: What is a safe calorie deficit for weight loss?
A: A deficit of 500-1000 calories per day is generally considered safe, resulting in 1-2 pounds of weight loss per week.

Q2: How do I calculate my TDEE?
A: TDEE can be estimated using formulas like Mifflin-St Jeor or Harris-Benedict, multiplied by an activity factor, or measured using fitness trackers.

Q3: Can too large a deficit be harmful?
A: Yes, extremely large deficits can cause muscle loss, nutrient deficiencies, metabolic slowdown, and other health issues.

Q4: Should I maintain the same deficit every day?
A: Weekly averages matter more than daily numbers. Some people prefer varying their intake throughout the week.

Q5: How accurate is calorie deficit calculation?
A: It provides a good estimate, but individual metabolic variations, measurement errors, and changing TDEE can affect accuracy.
