Obesity Is Linked To Changes In The Brain



What are we doing to our brains?

Our bodies?


The hypothalamus is a small almond sized structure situated just above the brain stem and controls body temperature, hunger, thirst, fatigue, sleep, and circadian cycles. These are functions in the category of homeostasis – or balance.  Look what we are doing!

Obesity appears to be strongly linked to structural changes in the brains of rats and humans, according to new research.
During a study of high-fat diets in the brains of mice and rats bred to become obese, researchers found evidence of early and lasting injury to a specific part of the hypothalamus.

Then using brain imaging, the researchers also found signs of similar damage in the same area of the brain in obese humans.
No one has found a cause and effect – but interesting questions are being asked and further studies will be designed.

If obesity changes what is basically the hunger thermostat – it might explain a lot about why people keep eating even when they know it may not be good for their health.

And this study was done on rats and adults so another question would be what happens to young children who are gaining so much weight? If their brains are also changed in not-so-good-ways by the weight, what else might that affect developmentally?

More questions that need answers!  But while we wait for more answers, please eat healthier foods and grow older better!!
