A Study to See How Safe a New Medicine (NNC6989-0001) is in Healthy People Living With Overweight or Obesity

Prior treatment

• Any clinically significant body weight change (≥5 % self-reported change) or dieting attempts (e.g., participation in a weight reduction program) within 90 days before screening.
• Treatment with any GLP-1 RA or a medication with GLP-1 activity within 90 days before screening
• Use of prescription or non-prescription medicinal products within 14 days before screening. This includes over the counter medicines such as laxatives, mineral oil, and fat-blocking supplements. Routine multivitamin/mineral supplements at labelled daily doses are permitted; other non-prescription supplements (e.g., high-dose vitamins, weight-loss supplements) are not permitted. Occasional use of over-the-counter acetaminophen or NSAIDs at their labelled doses for mild pain is permitted.

Other illness

• Any condition, which in the investigator's opinion might jeopardise participant's safety or compliance with the protocol.

• Male or female of non-childbearing potential.
• Age 18-55 years (both inclusive) at the time of signing the informed consent.
• Body mass index (BMI) (at screening) ≥ 25.0 and ≤ 34.9 kg/m\^2 for Part A (SAD part) and BMI (at screening) ≥ 25.0 and ≤ 39.9 kg/m\^2 for Part B (MAD part) and Part C (meal timing and potentially meal composition).
• Considered eligible based on the medical history, physical examination, and the results of vital signs, electrocardiogram, and clinical laboratory tests performed during the screening visit, as judged by the investigator.
