One pound is lost when you are able to create a deficit of 3500 calories per week. The calorie deficit can be created by cutting down calories from your daily consumption. You will have to make a few lifestyle changes that burn or reduce 10500 calories per week. As a first step, you will have to find your recommended calorie intake per day. For example, a man of age 30 who is sedentary should 2400 calories, a moderately active man of same age should eat 2800 calories and an active man should eat 3000 calories. Likewise a sedentary woman of age 30 should eat about 1800 calories, a moderately active woman should eat about 2000 calories and an active woman should eat about 2200 calories.
