Only 3 of 140 patients taking a placebo had similar problems.

Each group was compared to women who took a placebo.

Those taking a placebo lost an average of five pounds.

Only 1.1 percent of patients who took a placebo developed the condition.

Among those who took placebos, 11 percent a year developed diabetes.

Those taking a placebo took an average of 63 minutes to fall asleep in the sixth month.

Patients on the same diet who took placebos lost only 3.8 pounds.
