For the first month, rooms were maintained at 24, a 'thermo-neutral' temperature where the body does not have to operate to create or lose heat. Within   

the second month, the temperature new meizitang was moved right down to 19??C, then in the third month back to 24??C, and in the fourth month up to a toasty 27??C.

Researchers discovered that brown fat increased during the cool month, by around 30-40%, and fell throughout the warmest month.

For those who have diabetes or obesity, these findings bring promise, says first author from the study, endocrinologist Dr Paul Lee from Sydney's Garvan

Institute of Medical Research.

Adults posess zero large amount of brown fat, but people who do could be enjoying a better metabolism, better blood sugar control and a slimmer figure.

Contemporary lifestyles and widespread central heating, however, might be impairing brown fat function rather than improving it, suggests Lee.

Studies in the UK and US in the leisure 18 slimming coffee last many years show room temperatures in people's homes have climbed from about 19to 22.

"So along with unhealthy diet and lack of exercise, it's tempting to take a position the subtle transfer of temperature exposure might be a contributing step

to the increase in obesity," says Lee.

This latest study follows earlier research suggesting that shivering could stimulate the conversion of energy-storing 'white fat' into energy-burning brown

fat (also referred to as brown adipose tissue).
