The number of calories burned in a specific timeframe can vary greatly depending on several factors, including a person’s weight, metabolism, activity level, and the type of activity being performed.
For example:
- A person weighing around 150 pounds (68 kg) might burn approximately 3-5 calories per minute while walking at a moderate pace.
- Higher-intensity activities, like running or cycling, can burn significantly more calories in the same duration.
If you are doing a low-intensity activity, it might take longer than 60 seconds to burn 20 calories. Conversely, during high-intensity exercise, you might burn 20 calories in less than a minute.
If you provide details about the activity and specifics about your body, I could give a more tailored estimate.
