The DLW method has been used in people with obesity and other types of medical problems. It's recognized as the most accurate measure of the number of calories burned throughout a typical day, and how many calories are taken in from food and drink. By measuring these factors in people who take antipsychotic medications, doctors will gain a better understanding of the effects of antipsychotic medications on body weight and fat mass. This could lead to the development of better ways to prevent or treat weight gain or diabetes in patients who take antipsychotic medications.
