In the context of these recommendations, “metaboli- cally stable” indicates the absence of any active inflam- matory or infectious diseases, no hospitalization within 2 weeks, absence of poorly controlled diabetes and consumptive diseases such as cancer, absence of antibiotic or immunosuppressive medications, and absence of sig- nificant short-term loss of body weight. Another consid- eration is determination of body weight for diet prescription. Because the body weight suggested (whether IBW, BMI, usual or current, or adjusted) depends on clinician judgment related to the patient’s health goals (Guideline Statement 1.1.6), the specific weight formula used for prescription should be personalized to the patient.
