Inclusion Criteria

• Male or female.
• Age 18 years or above at the time of signing the informed consent.
• BMI between 25.0 and 45 kilogram per meter square (kg/m\^2) (both inclusive) at screening. Overweight should be due to excess adipose tissue, as judged by the investigator.

For participants with T2D:

• Diagnosed with type 2 diabetes (T2D) more than (>) 180 days before screening.
• Treatment with:

• no antidiabetic drugs or
• stable metformin dose or both [stable dose is defined as the maximum daily tolerated dose for more than or equal to (≥) 90 days before screening]

Exclusion Criteria

• Presence of clinically significant gastrointestinal disorders or symptoms of gastrointestinal disorders potentially affecting absorption of drugs or nutrients, or as judged by the investigator.
• History of major surgical procedures involving the oesophagus or stomach potentially affecting absorption of trial products (e.g. subtotal and total gastrectomy, sleeve gastrectomy, gastric bypass surgery) or current presence of gastrointestinal implant.

• Unusual meal habits and special diet requirements or unwillingness to eat the meals provided in the study.

For participants without T2D:

• Glycosylated hemoglobin (HbA1c) > 6.5 percent (%) 48 millimole per mole (mmol/mol) at screening.

For participants with T2D:

• HbA1c ≥ 10.5 % (91 mmol/mol) at screening.
• Current treatment with insulin or insulin secretagogues that might increase risk of hypoglycaemia during periods of fasting.
• Recurrent severe hypoglycaemia (more than 1 severe hypoglycaemic event within 180 days) or hypoglycaemic unawareness as judged by the investigator or hospitalisation for diabetic ketoacidosis within 180 days before screening
