The formula for calculating calories burned by steps and body weight is: calories burned per minute = 0.0175 x metabolic equivalent of the task (MET) x kilograms of weight.

1. Determine the MET of the activity.MET stands for Metabolic Equivalent of Task. MET represents the rate at which calories are burned while engaging in a physical activity. Different activities at different intensities have their own MET equivalents.

2. Calculate body weight in kilograms.

3. Note down the number of minutes taken to take 10,000 steps. Since this equation calculates calories burned per minute, the result needs to be multiplied by the total number of minutes it took to perform 10,000 steps to determine the total calories burned.

For example, if it took 1.5 hours (90 minutes) to complete 10,000 steps, the final equation would look like this: Calories Burned = 0.0175 x MET x Kilograms of Weight x 90 (minutes)

4. Plug the data into the equation.

Once the MET, weight in kilograms, and total minutes required to perform 10,000 steps have been determined, the data can be plugged into the equation and the estimate completed.

Expanded Information:

Calories burned in 10,000 steps are influenced by body weight and walking speed.

If you walk leisurely downhill at a speed of 3-4 miles (5-6 kilometers) per hour, you may burn between 3.5 and 7 calories per minute. A study of young people found that walking 10,000 steps at 4 miles (6 kilometers) per hour burned an average of 153 more calories than walking the same distance at 2 miles (3 kilometers) per hour.

Since it takes more energy to move a larger body than a smaller one, the theory is that larger bodies burn more calories when they move. Recent research suggests that after adjusting for weight, the number of calories burned through physical activity may not be higher in heavier people after all. Therefore, more research is needed to determine how body weight affects the number of calories burned while stepping.
