In the old days Medicare's CMN used to have a question that asked if the calories per day were within a certain range per the weight of the patient - cals per kg. The last time I had a patient on a very low calorie count I looked up the old formula, made the calculation and was surprised to find them OK. The patient was very small. If I find the formula or remember it I'll re-post but at the moment its escaping me!
