There are various factors you need to take into consideration to know how many calories an individual requires to lose weight. The weight loss process differs in each individual and the amount of weight one will lose also varies. Therefore, there is no fixed number that works for everyone. If you figure out how many you require to maintain your weight, you can calculate how many calories you require to lose weight. By knowing the basal metabolic rate you will be able to identify the amount of calories your body uses during rest. Multiplying this with another number based on the activity level you can calculate the extra calories that you have to burn through activities.
By following commercial weight loss programs like Nutrisystem one can lose weight at a steady pace and sustain the result as well.

To lose a pound you will have to create a deficit of 500 calories per day; therefore for losing 3 pounds a week you will have to create a deficit of 1500 calories per day. A moderately active man requires 2600 calories per day to maintain his weight. He needs to find a way to burn 700 calories through other activities. It is not possible for a sedentary woman to lose this much weight. As she would require 1800 calories a day she has to cut 600 calories and burn 900 calories through exercise to create a deficit of 1500 calories per day. Therefore it is recommended that you aim for weight loss that is a little more than one pound.
