My understanding of biochemistry is rather poor but I don't think weight is a factor here: > When consumed, aspartame becomes aspartic acid, phenylalanine, and methanol ― all of which can have potent effects on the central nervous system, the researchers point out. > Extrapolation of the findings to humans suggests that aspartame consumption at doses below the FDA recommended maximum daily intake may produce neurobehavioral changes in aspartame-consuming individuals and their descendants
