This study involved 200 people who were either overweight or obese and were also taking antipsychotics for serious mental illnesses; half of the study participants were enrolled in a year-long lifestyle intervention, the other half served as the control group and did not participate in the intervention.
Intervention participants lost nearly 10 more pounds than those in the control group during the weight loss phase of the study. They regained some of their weight during the weight maintenance phase of the study, but still weighed about 6 pounds less than people in the control group by the end of the intervention.
Intervention participants were also more than twice as likely as those in the control group to have normal fasting glucose levels at the end of the intervention period, and they had fewer medical hospitalizations (6.7 percent compared to 18.8 percent).
