A Research Study on How NNC0487-0111, a New Medicine, Works in Chinese Participants When Injected Under the Skin.

Inclusion Criteria: 1. Informed consent obtained before any study-related activities. Study-related activities are any procedures that are carried out as part of the study, including activities to determine suitability for the study. 2. Male Chinese participants, age 18-55 years (both inclusive) at the time of signing the informed consent. 3. Body mass index between 24.0 and 34.9 kg/m2 (both inclusive) at screening. Overweight and obesity should be due to excess adipose tissue, as judged by the investigator, with a body weight (more than or equal to) ≥ 65.0 kg at screening. 4. 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. Exclusion Criteria: 1. Any condition, unwillingness or inability which in the investigator's opinion might jeopardise participant's safety or compliance with the protocol. 2. HbA1c ≥ 6.5 percent (%) \[48 milimol per mole (mmol/mol)\] at screening. 3. Any laboratory safety parameters at screening outside the below laboratory ranges: * Vitamin D (25-hydroxycholecalciferol) less than (\<) 12 nanogram per mililiter (ng/mL) \[30 nanometer (nM)\] at screening * Parathyroid hormone (PTH) outside normal range at screening * Total calcium outside normal range at screening * Amylase ≥ 2 times upper limit of normal at screening * Lipase ≥ 2 times upper limit of normal at screening * Calcitonin ≥ 50 picogram per mililiter (pg/mL) at screening
