According to Nabisco, the manufacturer of Oreos, there are about 53 calories in each regular Oreo cookie, the number of calories a 155-pound adult burns while typing on the computer, watering the lawn or sitting at a desk doing office work for half an hour. It is also the number of calories expended when planting seedlings or raking the lawn for 20 minutes.
The number of calories burned during everyday activities depends on the size, age and sex of the individual as well as her personal metabolism. In general, people who are heavier, younger and more muscular burn calories at a faster rate. Choosing manual rather than electric tools, such as push mowers over gas mowers or rakes rather than leaf blowers, and scrubbing rather than using harsh cleansers, burns more calories. Taking multiple loads of laundry up or down stairs one load at a time involves more exercise than taking it all at once as does forgoing the elevator for the stairs.
There is a wide assortment of Oreo cookies available, from Double Stuff to Birthday Cake to Cool Mint Cream, with most varieties containing around 75 calories; the Chocolate Fudge-Covered Oreos and the Triple Double Neapolitan Oreos contain more than 100 calories each.
