1. What is Calorie Deficit?

A calorie deficit occurs when you consume fewer calories than your body expends. It's the fundamental principle behind weight loss, as your body must use stored energy (fat) to make up for the energy shortfall.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{TDEE} \) — Total Daily Energy Expenditure (calories your body burns per day)
• \( \text{Calories Intake} \) — Calories consumed through food and beverages

Explanation: A positive result indicates a deficit (weight loss), zero indicates maintenance, and a negative result indicates a surplus (weight gain).

3. Importance of Calorie Deficit

Details: Understanding and maintaining an appropriate calorie deficit is crucial for effective and sustainable weight loss. A moderate deficit of 500-1000 calories per day typically results in safe weight loss of 1-2 pounds per week.

4. Using the Calculator

Tips: Enter your TDEE (calculated through other methods or formulas) and your actual daily calorie intake. Both values should be in kcal/day. Ensure accurate tracking for meaningful results.

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 and sustainable, leading to 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 through metabolic testing.

Q3: Can too large a calorie deficit be harmful?
A: Yes, excessively large deficits can lead to muscle loss, nutrient deficiencies, metabolic adaptation, and other health issues.

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 for continued progress.

Q5: Is calorie deficit the only factor for weight loss?
A: While calorie deficit is primary, macronutrient distribution, meal timing, exercise type, and overall nutrition quality also play important roles in body composition and health.
