1. What is Calorie Deficit?

A calorie deficit occurs when you consume fewer calories than your body expends. This is the fundamental principle behind weight loss, as the body taps into stored energy (fat) to make up the difference.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (your maintenance calories)
• \( Deficit \) — The calorie reduction you want to implement

Explanation: To lose weight, you need to consume fewer calories than your body burns. A moderate deficit typically ranges from 300-500 kcal/day for steady weight loss.

3. Importance of Calorie Deficit

Details: Creating an appropriate calorie deficit is crucial for sustainable weight loss. Too large a deficit can lead to muscle loss and metabolic slowdown, while too small may not produce noticeable results.

4. Using the Calculator

Tips: Enter your TDEE (calculated from BMR and activity level) and your desired daily calorie deficit. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How much deficit should I aim for?
A: A 300-500 kcal/day deficit typically results in 0.5-1 lb weight loss per week, which is considered safe and sustainable.

Q2: What if my calculated calories seem too low?
A: Never go below 1200 kcal/day (women) or 1500 kcal/day (men) without medical supervision. Increase activity instead of reducing calories further.

Q3: Will I lose weight exactly as predicted?
A: Weight loss isn't linear due to water fluctuations, but over time, a consistent deficit will lead to fat loss.

Q4: Should I adjust my deficit as I lose weight?
A: Yes, as you lose weight your TDEE decreases, so you may need to periodically recalculate your needs.

Q5: Is calorie counting the only way to lose weight?
A: While effective, it's not the only method. Portion control, mindful eating, and food quality also play important roles.
