1. What Is This Calculator?

This calculator helps determine your daily calorie intake needed to lose 5 pounds per week based on your Total Daily Energy Expenditure (TDEE). It follows NHS guidelines for weight loss calculations.

2. How The Calculation Works

The calculator uses the following formula:

Where:

• 5 — Pounds to lose per week
• 0.4536 — Conversion factor (pounds to kg)
• 7700 — Calories per kg of body weight
• 7 — Days in a week
• TDEE — Your Total Daily Energy Expenditure

Explanation: This creates a daily calorie deficit equivalent to 5 pounds of weight loss per week.

3. Importance of Safe Weight Loss

Details: While this calculator shows the deficit needed for 5lb/week loss, NHS generally recommends 1-2lb/week for sustainable weight loss. Rapid weight loss should be medically supervised.

4. Using The Calculator

Tips: Enter your accurate TDEE (use a TDEE calculator if unsure). The result shows the daily calories needed for 5lb/week weight loss.

5. Frequently Asked Questions (FAQ)

Q1: Is 5 pounds/week weight loss safe?
A: For most people, this is an aggressive target and should only be attempted under medical supervision.

Q2: How do I find my TDEE?
A: Use an online TDEE calculator that considers your age, gender, weight, height, and activity level.

Q3: Why 7700 calories per kg?
A: This is the estimated energy equivalent of 1kg body fat (approximately 7700 kcal).

Q4: Will I lose exactly 5 pounds each week?
A: Results vary based on individual metabolism, adherence, and other factors. Initial weeks may show more loss from water weight.

Q5: What if I feel unwell on this plan?
