Hello, I'm a fitness expert with a background in sports science. When it comes to burning calories through walking, there are several factors to consider, such as the individual's weight, walking speed, and the duration of the walk.

To give you a general idea, a person weighing 150 pounds (68 kg) can burn approximately 100 calories in 30 minutes of walking at a moderate pace. However, this is a rough estimate and the actual number of calories burned can vary.

Here's a more detailed breakdown:


1. Weight: Heavier individuals burn more calories for the same amount of activity than lighter individuals.

2. Speed: Walking faster will burn more calories in the same amount of time.

3. Duration: The longer you walk, the more calories you'll burn.

4. Intensity: Incorporating hills or intervals can increase the calorie burn.

It's important to note that while walking is a great way to increase daily activity and contribute to overall health, it's just one part of a balanced fitness routine and a healthy lifestyle that includes a balanced diet.
