1. What is Daily Calorie Intake For Weight Loss?

Daily calorie intake for weight loss is calculated by determining your total daily energy expenditure (TDEE) and subtracting a calorie deficit, typically 500 calories per day, to achieve a safe and sustainable weight loss of about 0.5-1 kg per week.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Intake} = \text{BMR} \times \text{PAL} - 500 \]

Where:

\( \text{BMR} \) — Basal Metabolic Rate (calories burned at rest)
\( \text{PAL} \) — Physical Activity Level multiplier
\( 500 \) — Calorie deficit for weight loss

Explanation: This equation calculates your maintenance calories (BMR × PAL) and subtracts a 500-calorie deficit to create the energy imbalance needed for weight loss.

3. Importance of Calorie Deficit

Details: A 500-calorie daily deficit creates a 3500-calorie weekly deficit, which typically results in about 0.5 kg (1 lb) of fat loss per week. This moderate approach supports sustainable weight loss while preserving muscle mass.

4. Using the Calculator

Tips: Enter your BMR (calculated separately) and select your appropriate PAL level based on your daily activity. Ensure accurate BMR calculation for best results.

5. Frequently Asked Questions (FAQ)

Q1: Why a 500-calorie deficit?
A: A 500-calorie deficit is recommended as it creates sustainable weight loss of about 0.5-1 kg per week without being too restrictive.

Q2: How do I calculate my BMR?
A: BMR can be calculated using formulas like Mifflin-St Jeor or Harris-Benedict, which consider age, gender, height, and weight.

Q3: What PAL level should I choose?
A: Choose based on your daily activity: Sedentary (office work), Lightly Active (light exercise 1-3 days/week), Moderately Active (moderate exercise 3-5 days/week), Very Active (hard exercise 6-7 days/week), Extremely Active (athlete/training 2x daily).

Q4: Is 500 calories too aggressive for some people?
A: For individuals with lower TDEE, a 500-calorie deficit might be too aggressive. In such cases, a smaller deficit of 250-300 calories may be more appropriate.

Q5: Should I adjust my intake as I lose weight?
A: Yes, as you lose weight, your BMR decreases. Recalculate your calorie needs every 4-6 weeks or after significant weight loss (5+ kg).
