Now we have one more reason to lose weight - a better memory-Believe it or not!!

This is interesting and gives reason for thinking about weight in a different way, it is not the gospel of truth, however it is worth consideration.
We already know that being overweight can cause a truckload of health problems, including heart disease, high blood pressure, diabetes and strokes.
There’s new evidence that being obese can mess with your brain, causing serious memory loss.
There’s also hope that losing weight can help repair the damage.
The study was conducted at Kent State University and led by John Gunstad, an assistant professor of psychology.
Aware of previous studies linking obesity to memory loss, Gunstad and his team wanted to find out if losing weight could reverse the problem.
Another study reported by Diana Kerwin, the lead author of the study shown below could indicate similar results.
Based on 8,745 post-menopausal women, aged 65 to 79, who took a 100-point memory test. The score for normal memory is in the 90- to 100-point range. After completing the test, the score for each woman was matched to her Body Mass Index, or BMI.
It's a standardize measure based on weight and height.
The study revealed that for every one point increase in a woman's BMI, her memory score dropped by one point. “Any excess fat appears to be detrimental,” said Diana Kerwin.
Previous research has shown that other conditions, including high blood pressure, elevated cholesterol levels and diabetes, can affect blood flow to the brain and impair cognitive function.
These medical conditions often go along with being overweight.
However, even when those conditions are not present, excess weight was still tied to reduced memory among the study participants.
That suggests weight, by itself, is an independent risk factor for memory loss.
