Individuals who burn 500 more calories a day than they consume can lose one to two pounds in a week. To increase this to two to three pounds, eating 1,050 to 1,200 calories and exercising for an hour is necessary. Weight loss levels aren't guaranteed in each person, but taking this approach is a healthy way to lose weight in three weeks.
For fast but healthy weight loss, eating fruit and vegetables, lean protein and nonfat dairy foods is essential. In addition, reducing sugars and foods high in fat is helpful.

In addition, increasing physical activities in and out of the home is helpful; for example, cleaning, walking to work and shopping.
