1. What is the 800 Calorie Weight Loss Calculator?

This calculator estimates potential weight loss when maintaining an 800 calorie daily deficit from your TDEE (Total Daily Energy Expenditure). It's based on the principle that 7700 calories equals approximately 1 kg of body weight.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (kcal/day)
• \( 800 \) — Daily caloric deficit (kcal)
• \( days \) — Duration of deficit (days)
• \( 7700 \) — Calories needed to lose 1 kg (kcal/kg)

Explanation: The formula calculates the total caloric deficit over time and converts it to kilograms of weight loss.

3. Importance of Caloric Deficit

Details: A consistent caloric deficit is the foundation of weight loss. An 800 kcal deficit is considered aggressive but sustainable for many individuals when properly managed.

4. Using the Calculator

Tips: Enter your accurate TDEE (use a TDEE calculator if unsure) and the number of days you plan to maintain the deficit. Results are estimates - actual weight loss may vary.

5. Frequently Asked Questions (FAQ)

Q1: Is an 800 calorie deficit safe?
A: For most healthy adults, yes, but consult a healthcare provider before starting any aggressive weight loss plan.

Q2: Why 7700 calories per kg?
A: Research shows approximately 7700 kcal deficit equals 1 kg fat loss, though this can vary slightly between individuals.

Q3: Will I lose exactly this amount of weight?
A: This is an estimate. Actual results depend on metabolic adaptation, water retention, and other factors.

Q4: Should I eat 800 calories per day?
A: No! This calculates an 800 kcal deficit from your TDEE. Eating below 1200 kcal/day (women) or 1500 kcal/day (men) is generally not recommended without medical supervision.

Q5: How can I increase my weight loss?
A: Combine diet with exercise, but avoid extreme deficits which can be counterproductive and unhealthy.
