Determining how many calories it takes to lose weight is dependent upon a number of variables. Individuals need to take into consideration how much weight they want to lose, how active they are and if they have any medical conditions that would slow the metabolism. For example, people with a sedentary lifestyle will need to consume less calories in order to lose weight than those who are very active. In addition, people who have certain medical conditions such as a sluggish thyroid may find that they need to cut calories even further in order to achieve their weight loss goals.
