Eating around 1000 calories a day and exercise intensely every day how quickly to lose a pound?

Eating 1000 calories a day and exercising intensely is actually an unhealthy choice. The average person should consume + or - 500 calories from 2000 calories, depending on the individual person and their lifestyle. One pound of fat is equal to 3,500 calories. When 3,500 calories of fat is burned, that is equal to losing one pound of fat. This should be done by eating foods with high protein and monounsaturated fats, while avoiding saturated fats, and getting physical activity on a daily basis.
