"Researchers at Aberdeen University found that obese people produced 10 per cent less vitamin D than people of average weight. The study also found that excess body fat absorbs vitamin D, stopping it entering the bloodstream."
Here is also some insight in to why a lack of vitamin D can help lead to obesity...
"The study found that low levels of the vitamin in blood interfered with the function of a hormone called leptin, which tells the brain when the stomach is full."

Remember, the Sun is your friend!
As I have done my own experimenting with vitamin D over the Summer, I have noticed improvements in my skin and mood when I get my daily dose of sunshine. While my weight hasn't changed, my body composition is still changing and I am still losing inches. I have not really noticed a difference in appetite , but I really wasn't paying attention and it fluctuates wildly anyway. These clues about the interaction of vitamin D and leptin are very interesting.
According to metabolic specialist, Dr. Ron Rosedale, author of The Rosedale Diet :
"Leptin is the way that your fat stores speak to your brain to let your brain know how much energy is available and, very importantly, what to do with it. Studies have shown that leptin plays significant, if not primary, roles in heart disease, obesity, diabetes, osteoporosis, autoimmune diseases, reproductive disorders, and perhaps the rate of aging itself."
By following standard medical advice to eat plenty of carb and stay out of the sun, we set ourselves up for a lot of diseases, like heart diases, diabetes, obesity and more. Good thing I choose to ignore people who seem hell bent on keeping me fat and sick. As more information comes out about the role of vitamin D in health and obesity, I will be sure to post it. In the mean time, I will be out in the sun, without sun screen, reading a good book. It's for my health ya know!
