Summary
The cephalic phase of reflex insulin secretion was studied in normoglycemic and normoinsulinemic
female patients, obese (more than 30% over IBW) and normal subjects.
After an overnight fasting, at the sight of breakfast food, the obese group did not
present a cephalic response. Their glycemia and insulinemia levels remained at base
levels.
One minute after visual and olfactory stimulation, a statistically significant rise
in immunoreactive insulin levels which was maintained throughout the test, was observed
in the control group.
