ASPARTAME is an artificial sweetener consisting of the
two amino acids-- phenylalanine and aspartic acid-- that when
ingested "tastes" sweet. This sweet taste can sometimes
trick your body into releasing insulin (something undesireable on the
ketogenic diet); however, we must realize that although insulin
is released, there are still no carbohydrates present. ASPARTAME,
therefore, may cause LIGHTHEADEDNESS due to too much
insulin release, however, it will not take a person out of ketosis.
