Researches at Aberdeen university studied over three thousand women in Scotland and concluded that a lack of vitamin D caused by a lack of sunshine could be the reason why so many people in Scotland are obese. Those with a body mass index of thirty four produced ten percent less vitamin D compared with those of average weight.
The belief is either they are not getting enough sun or the vitamin D they do have is stored in fat cells and therefore not available. A lack of this vitamin interferes with the hormone leptin which tells the brain when the stomach is full.
This lack of vitamin D may also contribute to heart disease, cancer lowered immune function.
