People normally associate extra weight with the winter season since people tend to stay more indoors and eat a bunch of junk food. Think of your body as a furnace. When the temperature outside is 98.6 degrees, your body doesn’t need to burn much fuel to maintain a normal temperature.
When the temperature is 30 degree outside, though, your body needs to burn massive amounts of fuel to maintain its temperature. When you’re sleeping, keep your room at a cool 65 degrees or so compared to a subtropical 76. As much as you’d like to pretend you’re sleeping in Tahiti, it may not be the best idea. You can burn calories in your sleep by being cold, and who the heck wouldn’t want to lose weight while sleeping? It’s the easiest thing you’d do all day!
