1. What is the 800 Calories A Day Calculator?

The 800 Calories A Day Calculator determines the calorie deficit when consuming 800 calories per day compared to your Total Daily Energy Expenditure (TDEE). This helps in planning very low-calorie diets for weight loss purposes.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• \( \text{TDEE} \) — Total Daily Energy Expenditure (calories burned per day)
• \( 800 \) — Fixed daily calorie intake
• \( \text{Deficit} \) — Daily calorie deficit

Explanation: This calculation shows how many fewer calories you're consuming compared to what your body burns daily.

3. Importance of Calorie Deficit Calculation

Details: Understanding your calorie deficit is crucial for effective weight loss planning. A deficit of 500-1000 calories per day typically leads to 1-2 pounds of weight loss per week.

4. Using the Calculator

Tips: Enter your accurate TDEE value in calories. Ensure you have calculated your TDEE properly through reliable methods or calculators before using this tool.

5. Frequently Asked Questions (FAQ)

Q1: Is 800 calories per day safe?
A: 800 calories per day is considered a very low-calorie diet and should only be undertaken under medical supervision. It's not suitable for long-term use.

Q2: How do I calculate my TDEE accurately?
A: TDEE can be calculated using formulas that consider your basal metabolic rate (BMR) and activity level, or through professional metabolic testing.

Q3: What's a sustainable calorie deficit?
A: Most health professionals recommend a deficit of 500-750 calories per day for sustainable weight loss of 1-1.5 pounds per week.

Q4: Can I exercise on 800 calories per day?
A: Intense exercise is not recommended on such a low calorie intake. Light activities may be possible but consult with a healthcare provider.

Q5: How long can I safely follow an 800-calorie diet?
A: Very low-calorie diets are typically limited to 12 weeks or less and should always be medically supervised.
