Breast Cancer, Obesity, Overweight
Conditions
Brief summary
Obesity among breast cancer survivors is known to be associated with recurrence and other co-morbidities. However, there have been no studies on weight reduction program combining diet and anti-obesity drug for obese breast cancer survivors. The purpose of this randomized clinical trial is to examine the effects of Mediterranean Diet and naltrexone/bupropion treatment on inflammation and metabolic risk factors in overweight or obese breast cancer patients after breast cancer treatment.
Interventions
Naltrexone hydrochloride (HCl) 8 mg/Bupropion hydrochloride (HCl) 90 mg extended release (ER) combination tablets, orally, one tablet, in the morning, daily, for 1 week, followed by Naltrexone HCl 8 mg/Bupropion HCl 90 mg ER combination tablets, orally, one tablet in the morning and one in the evening, daily, for 7 weeks.
Diet instruction and menu samples from the dietitian on following the Mediterranean Diet.
