Believe it or not, there may actually be something - positive - coming out of our current stretch of cold weather. According to a new study - exposure to colder temperatures might actually help you lose weight. Channel 4's Scott Johnson spoke to a local doctor about the study..Scott joins us LIVE. 3 3 00-1020-27 if you're tired of the cold weather it may be understandable.... but if you're trying to lose weight don't be so quick to grumble over old man winter because new studies out of canada and the netherlands shows cold temperatures can actually help with weight loss.We sat down with dr.miro Uchal at St. Vincent's HealthCare. He tends to think the study may be accurate.14:35 - 30% of your energy is used for body heating, because we are warm creatures, so we need to heat up this body, if you're in a cold environment, we need to make more heat and hopefully give up more energy out.... you'll be leaner. the studies show there are two types of fat ... one called brown fat... which is used often in heating the body. It's good fat that can help you be thinner... then there's white or more yellowish fat that collects in the hips ... thighs and stomach.The study shows colder temperatures cause the brown fat to work more - even jump starting it in some cases - and once it starts, it burns off the lighter-colored fat.13:30 - the brown fat is actually good for you, deeper than the yellow fat. And so giving up the heat and the energy and it's burning the energy or calories for you.but dr. Uchal says weight loss isn't as simple as keeping your room temp ten degrees cooler than usual...he says often there are a lot of factors that go into weight loss. Still this may help.12:59 - all heat is trapped inside this area and may be influencing how we metabolize sugar, how hormones work, how pancreas works and I believe there is a lot of truth in that. 3 3 Scott, how did researchers discover this? What were their methods?
