Brief summary

The main purpose of this study is to find out how much LY3537031 gets into the blood stream and how long it takes the body to get rid of it when it is injected just under the skin in different parts of the body, and when it is injected into a vein, in healthy participants. This study will also look at the safety and tolerability of LY3537031.

Exclusion criteria

* Have significant history or current cardiovascular, respiratory, hepatic, renal, Gastrointestinal (GI), endocrine, hematological, dermatological, or neurological disorders that, in the opinion of the investigator, are capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study intervention; or interfering with the interpretation of data. * Have a history of atopy; that is, severe or multiple allergic manifestations, or clinically significant multiple or severe drug allergies, or hyperesthesia, or severe post treatment hypersensitivity reactions, or have known allergies to LY3537031, Glucagon-Like Peptide-1 (GLP-1) analogs, or related compounds. * Have undergone any form of bariatric surgery. * Have a diagnosis or history of malignant disease within 5 years before screening, with the following (some exceptions are allowed) * Have a history of or current acute or chronic pancreatitis, or elevation in serum lipase or amylase or both greater than 1.5× Upper Limit of Normal (ULN). * Have a history of chronic liver disease, acute or chronic hepatitis, including a history of autoimmune hepatitis, or any evidence for hepatic impairment. * Have a family or personal history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome Type 2.
