Weight Loss and Loss of Appetite
According to PubMed Health, researchers at Duke University conducted a study to determine the weight loss characteristics of Wellbutrin in obese adult women. Along with a 1,600-calorie-per-day balanced diet, participants were given Wellbutrin or a placebo. It was determined that those who received the Wellbutrin achieved a weight loss over 5 percent of baseline body weight. Although the exact mechanism for losing weight while taking Wellbutrin is not known, it is suspected that it is linked with the loss of appetite and nausea experienced by some who take it.
