Presented here are the outcomes and discussion of the FIT-PLESE clinical trial for women with infertility and obesity. Protocol involved all participants to increase their physical activity, and half were randomized to an intensive group treated with open-label anti-obesity medication (Orlistat), nutritional counseling, and meal replacement products for 16 weeks. This study showed that an average of 7% weight loss did not improve the rate of having any live birth or a healthy live birth but did improve participants’ cardiometabolic health.
