When estimating calorie burn while walking, there are several factors to consider, including weight, distance, pace, and individual metabolism. Given your specifics:

1. For the man weighing 56 kg: The general estimate for calories burned while walking is about 0.5 to 1 calorie per kilogram per kilometer. For brisk walking, the value tends toward the higher end.

2. Calculation:

   • Distance: 7 km.
   • Weight: 56 kg.
   • Estimated Calories Burned = Weight (kg) x Distance (km) x 0.5 (brisk walking) = 56 kg x 7 km x 0.5 ≈ 196 calories.
   • For more active walking, this could increase up to about 0.8 calories per kg per km: 56 kg x 7 km x 0.8 = 313 calories.

3. For the man weighing 61 kg: Using the same formula, you can estimate:

   • Estimated Calories Burned = 61 kg x 7 km x 0.5 ≈ 213 calories.
   • Or with a brisker pace: 61 kg x 7 km x 0.8 = 341 calories.

Summary of Calorie Estimates:

• Man weighing 56 kg: approximately 196 to 313 calories.
• Man weighing 61 kg: approximately 213 to 341 calories.

Which Source is More Accurate?

Both your AI source and online calculator are likely accurate within a range reflecting different walking speeds and individual metabolism. However, the lower estimates might be more conservative, while the higher estimates consider more active walking.

Next Steps:

1. Monitor Your Activity: If you're walking regularly, track your pace and how you feel, adjusting your activity level for accuracy in estimating calories.
2. Use a Heart Rate Monitor: For more personalized calorie counts, consider using a fitness tracker or an app that adjusts for your heart rate during exercise.
3. Stay Hydrated and Nourished: Ensure you're properly fueled before and after your walk to support your energy levels.
