In order to lose 20 pounds in a month, a person has to lose 5 pounds per week. This means the person needs to burn 17,500 more calories than they consume for the week since one pound of fat equals 3,500 calories. That breaks down to a calorie deficit of 2,500 calories per day.
Burning calories through exercise is necessary for this type of weight loss. When determining how much exercise is necessary, a person should add the number of calories consumed plus 2,500 calories for the deficit. The resulting answer is how many calories must be burned during the day. For example, a person who eats 2,000 calories per day would need to burn 4,500 calories each day.
The exercise a person does is up to that person. Even common cleaning activities can count toward calories burned, according to the National Heart, Lung and Blood Institute. Raking leaves for 30 minutes or shoveling snow for 15 minutes are moderate intensity household tasks that can aid in weight loss.Learn more about Fitness & Exercise
