Practical Example

Let’s say John wants to plan his weight loss journey:

• Current Weight: 85 kg
• Target Weight: 75 kg
• Weekly Goal: 0.5 kg
• Activity Level: Moderately Active
• Age: 30

Using the calculator:

• Total Weight to Lose: 85 – 75 = 10 kg
• Estimated Weeks: 10 ÷ 0.5 = 20 weeks
• Calories per kg: 7700 kcal
• Total Calories to Burn: 10 × 7700 = 77,000 kcal
• Calories per Week: 77,000 ÷ 20 = 3,850 kcal
• Calories per Day: 3,850 ÷ 7 ≈ 550 kcal

John now knows that by burning roughly 550 calories per day, along with maintaining his activity level, he can safely reach his goal in 20 weeks.
