Research published in Journal of Clinical Investigation studied 12 young men who had lower-than –average amounts of brown fat were asked to sit for 2 hours /day in 63 degree Fahrenheit (17.22 celsius) room for 6 weeks. They burned an extra 108 calories compared to normal room temperature. Even better , after 6 weeks they were burning an extra 289 calories. Researchers hypothesis was that exposure to lower temperatures increased the activity of a gene that converts white fat to brown.
Conclusion- Turn down the thermostat a bit in your home.
