When the calories you burn equal the calories you eat, you reach a plateau. To lose more weight, you need to either increase your physical activity or decrease the calories you eat.

It takes 20 steps to burn 1 calorie, therefore walking 10,000 steps burns off about 500 calories, which can then be added to your total calorie budget for the day. The recommended daily calorie requirement is 1,800 for an average female and 2,200 for an average male.
