Methods and compositions are generally provided for treating metabolic disorders, e.g., obesity. One aspect discloses methods and compositions for obtaining a biological sample from the subject, evaluating the sample for the presence or absence of a genetic indicator, wherein the genetic indicator is selected from a single nucleotide polymorphism and a level of gene expression, and performing a first metabolic procedure if the genetic indicator is present, or performing an alternative second metabolic procedure if the genetic indicator is absent. One aspect discloses methods and compositions for obtaining a sample including deoxyribonucleic acids (DNA) from the subject, evaluating the DNA for an absence or presence of one or more genetic indicators and performing a first metabolic procedure or an alternative second metabolic procedure based on the absence or presence of the genetic indicator(s). Other aspects are also disclosed.
