1. What is Calorie Deficit?

Calorie deficit occurs when you consume fewer calories than your body expends. 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 formula:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (calories your body burns per day)
• \( Intake \) — Calories consumed through food and beverages
• \( Deficit \) — The resulting calorie shortfall

Explanation: A positive deficit indicates weight loss potential, while a negative deficit (surplus) indicates weight gain.

3. Importance of Calorie Deficit for Weight Loss

Details: Creating a consistent calorie deficit is the fundamental principle behind weight loss. Understanding your daily deficit helps you plan sustainable weight loss strategies and avoid excessive restriction that can harm metabolism.

4. Using the Calculator

Tips: Enter your TDEE (calculated through online calculators or fitness trackers) and your daily calorie intake. Both values should be in kcal/day. For healthy weight loss, aim for a deficit of 300-500 kcal per day.

5. Frequently Asked Questions (FAQ)

Q1: What is a safe calorie deficit for weight loss?
A: A deficit of 300-500 kcal per day is generally safe and sustainable, leading to 0.5-1 pound of weight loss per week.

Q2: Can the deficit be too large?
A: Yes, deficits larger than 1000 kcal/day can cause muscle loss, nutrient deficiencies, and metabolic adaptation that slows weight loss.

Q3: How do I calculate my TDEE accurately?
A: Use online TDEE calculators that factor in your age, weight, height, gender, and activity level. For more precision, consider metabolic testing.

Q4: Should I maintain the same deficit every day?
A: Some people benefit from calorie cycling - varying intake throughout the week while maintaining the same weekly deficit.

Q5: What if my deficit isn't producing weight loss?
A: Re-evaluate your TDEE calculation, track intake more accurately, consider metabolic adaptation, or consult a healthcare professional.
