Summary

This trial is testing if a hormone can help obese people lose weight by boosting their metabolism.

Who is the study for?
This trial is for healthy, non-diabetic obese adults aged 18-55 with a BMI of 27 to 45 kg/m2 and stable weight. Participants must not have significant health issues, take certain medications affecting weight or energy metabolism, or have had bariatric surgery. They should not be pregnant, breastfeeding, or unwilling to use birth control if applicable.
What is being tested?
The study tests the effects of glucagon versus placebo on energy expenditure over a period of 72 hours in obese individuals. It aims to understand how prolonged glucagon administration can influence calorie burning in the body without any dietary changes.
What are the potential side effects?
Potential side effects may include reactions at the injection site, nausea due to increased glucose levels in blood (hyperglycemia), and possible low blood sugar (hypoglycemia) if too much insulin is released in response.
