Healthy, Overweight or Obesity

Brief summary

The purpose of this study is to evaluate how well LY4064912 is tolerated and what side effects may occur in healthy participants and participants with overweight and obesity - global. The study drug will be administered either subcutaneously (SC) (under the skin) or infusion intravenously (IV) (into a vein in the arm). Blood tests will be performed to investigate how the body processes the study drug and how the study drug affects the body.
