The cold weather might just help you burn more calories, according to some experts.
They claim that spending time in cooler temperatures can boost calorie burn by up to 30%.
It's all to do with 'brown fat' - which is the opposite of unhealthy white fat. According to scientists, brown fat actually helps the body burn energy in the form of heat.
Apparently, spending several hours a day in cold temperatures increases the amount of brown fat in the body, so you stay warmer and burn more calories in the process.
