The researchers acknowledged drawbacks of the study. For example, they were unable tobody fat obesity Burning brown t to be slimmer has a hitch tell whether brown t was metabolically active during cold conditions in other internal organs such as the heart because of the limited view of the PET/CT scanner.
Scientists and drug companies are interested in finding way to increase the amount of brown adipose tissue, also calledbrown t, in adults in the hopes of fighting obesity.
Scientists in Quebec designed an experiment to find out.

Based on the radioactivity findings, the researchers concluded all of the men showed cold-induced activation of brown t metabolism.However, it remains to be demonstrated whether chronic and frequent bouts of cold exposure may contribute to increase [brown t metabolism] and/or activity and may be a viable adjunct therapeutic strategy to other lifestyle interventions to prevent or treat obesity and its metabolic complications, they concluded in Tuesdays issue of the Journal of Clinical Investigation.

Our brown t is metabolically active only during cold.They knew that rodents and newborn babies burn calories from brown t to keep warm. Animals and newborns dont shiver.
When the investigators exposed the men to a radioactive chemical, they found the radioactivity disappeared from the brown t in just minutes, but the radioactivity wasnt metabolized in the warm subjects.
