1. What is Calorie Deficit?

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

2. How Does the Calculator Work?

The calculator uses the simple deficit formula:

Where:

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

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

3. Importance of Calorie Deficit

Details: Maintaining a consistent calorie deficit is the fundamental principle behind weight loss. Understanding your deficit helps create sustainable weight management strategies and prevents excessive restriction that can harm metabolism.

4. Using the Calculator

Tips: Enter your TDEE (calculated through various 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/day.

5. Frequently Asked Questions (FAQ)

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

Q3: How do I calculate my TDEE accurately?
A: Use online TDEE calculators that consider age, weight, height, gender, and activity level, or track your intake and weight changes over time.

Q4: Should I maintain the same deficit every day?
A: Consistency is key, but small variations are normal. Focus on weekly averages rather than daily perfection.

Q5: What if my deficit calculation shows negative numbers?
A: A negative deficit means you're in a calorie surplus, which leads to weight gain. Adjust your intake or increase activity to create a deficit.
