Participant testing protocol. All participants initially received 10-s exposures to full-fat and nonfat stimuli on separate days held about 1 wk apart. Those exhibiting a triacylglycerol (TAG) increase of >10 mg/dl within 30 min of pill ingestion received these exposures again to assess response reliability. Individuals who did not exhibit a TAG rise of this magnitude next received 20-min exposures to the 2 stimuli. Those exhibiting a TAG rise next received 5-min exposures, and those failing to exhibit a TAG rise received 2 h of exposure to the full-fat and nonfat stimuli. The identical protocol was conducted for 22 individuals receiving no oral stimulation as a control for time effects.
