Well maybe it is a factor, but somehow the solution of freezing to death to lose weight sounds pretty noxious. "Warm Houses in Winter May Contribute to the Obesity Epidemic" But it makes one wonder what other factors are out there, besides the bad frankenfood, could "modern" life in general via lack of sunlight, warm houses that keep the body from having to fire up the engine and even 24/7 light affect fat? It's an interesting study, at least here is one study where they are thinking outside the box. [The best studies are coming from overseas, and this one is from Britain]
"Increased time spent indoors, widespread access to central heating and air conditioning, and increased expectations of thermal comfort all contribute to restricting the range of temperatures we experience in daily life and reduce the time our bodies spend under mild thermal stress -- meaning we're burning less energy. This could have an impact on energy balance, and ultimately have an impact on body weight and obesity," study author Fiona Johnson, a researcher in the department of epidemiology and public health at University College London, said in a UCL news release."
