Summary

This trial is studying how the body burns calories when exposed to different temperatures and how brown fat burns calories in cold temperatures.

Who is the study for?
Healthy men aged 18-35 or 55-75 and healthy women aged 18-35, who are non-Hispanic whites or African Americans. Excluded are those with high blood pressure, certain BMI ranges, diabetes, abnormal kidney function, recent drug/alcohol abuse, metal implants incompatible with MRI scans, cardiovascular disease, liver disease, iron deficiency and other specific health conditions.Check my eligibility
What is being tested?
The study is examining how the body's energy expenditure changes in response to different room temperatures ranging from about 61°F to 88°F. It aims to understand the role of brown fat in calorie burning during cold exposure by monitoring body temperature and activity levels.See study design
What are the potential side effects?
There may be minimal side effects since this trial involves environmental temperature changes rather than medication or invasive procedures. However participants might experience discomfort due to cold or hot sensations when exposed to varying temperatures.
