One day, I was bored and looked up the calories in dirt. It turns out it is really healthy, and only has 6 calories in 15 pounds. I have no clue why you would want to eat 15 pounds of dirt, but MyFitnessPal has it listed as the serving size (https://www.myfitnesspal.com/food/calories/dirt-359365006). Although it is a bit fattening, I must admit it is extremely addicting. Also yeah you can burn off all those 15 pounds with 2 minutes of cleaning.
