Researchers are looking for new weight loss medicines for people with higher body weight. The study medicine, MK-4082, is different from similar weight loss medicines because people take it as a pill instead of an injection. Before giving a study medicine to people with a health condition, researchers first do studies to find a safe dose level (amount) of the study medicine that can be used in future studies. The goals of this study are to learn about: * The safety of MK-4082 and if people tolerate it * What happens to different MK-4082 dose levels in a person's body over time
