title: Predicting energy needs in obese patients.
abstract: Obesity has become an epidemic in the United States, with other western countries also reporting increases in incidence of obesity. With many associated comorbidities, it is the most common nutritional disorder facing the medical team. However, the assessment of macronutrient needs for nutrition support regimens in obese adults is controversial. This review summarizes existing research on popular predictive approaches, including the Harris-Benedict equation, kilocalories per kilogram, and the Ireton-Jones equations. Complications including special considerations for patients who have undergone bariatric surgeries and current evidence on hypocaloric regimens are also discussed.
