2. Input Your Target Weight (kg)
This is the weight you aim to achieve. It must be lower than your current weight.
3. Enter Duration in Weeks
Specify how many weeks you want to take to reach your target weight. Keep in mind, a healthy weight loss rate is typically 0.5 to 1 kg per week.
4. Click Calculate

🧪 Example Calculation
Let’s walk through a real example:
- Current Weight: 85 kg
- Target Weight: 75 kg
- Duration: 10 weeks
The Result:
- Weight to Lose: 10 kg
- Total Calories to Burn: 10 × 7700 = 77,000 kcal
- Daily Calorie Deficit: 77,000 ÷ (10 × 7) = 1,100 kcal/day
This means you need to maintain a daily calorie deficit of about 1,100 kcal over the next 70 days to reach your goal.
📌 Interpreting the Results
🔹 Daily Calorie Deficit
This is the shortfall between your calorie intake and calorie expenditure. You can achieve this through:
- Eating fewer calories
- Increasing physical activity
- Combining both
🔹 Total Calories to Burn
This shows the total energy (in kcal) your body needs to expend to shed the excess weight. It’s a valuable figure when planning long-term routines.
🧠 Tips for Using Your Results
- Avoid crash dieting – Never aim for more than a 1000–1200 kcal/day deficit without medical supervision.
- Focus on sustainable habits – Balanced meals and consistent exercise are key.
- Track your progress – Apps or journals can help track calorie intake and workouts.
- Consult a professional – Always check with a healthcare provider before beginning a new diet or fitness plan.
