NCT03563885

NCT01870947
This is an assisted exercise trial involving exercise on a stationary bike, brain imaging and DNA(genetics)sampling. The purpose of this study is to find out if performing a progressive, supervised assisted exercise program on a stationary bike improves quality of life, increases motivation to continue to exercise, improves dietary behavior and leads to sustained weight loss in women who have had early-stage endometrial cancer. Questionnaires will be used to assess exercise motivation and dietary behavior. Brain's responses to different visual images will also be assessed.
NCT03198143
This study evaluates the effect of the "hunger hormone" ghrelin on human decision-making. Participants will be given an injection of ghrelin or saline on different study days and will then be asked to make a series of computer-based decisions. The investigators hypothesize that ghrelin will increase participant's preference for energy-dense foods and will also increase impulsiveness in decision making.
