Obesity and a Happy Brain

Wednesday, January 28th, 2009

Brain HealthAs most of us get into middle age we might take special notice of our body’s ability to keep a few extra pounds around the waist. Most of us understand the importance of eating healthy and the disease risk associated with extra weight around the belly.

Recent research suggests the brain’s ability to sense gratification may be critical to overeating behavior. We may have a gene that assists us with knowing when we are filled after eating. Research now indicates that a brain that does not express satiation will lead to continued eating and increased risk of obesity.

We know that a healthy diet and regular exercise are very important for maintaining a healthy weight and avoiding obesity. However, genetics also plays a role in which an important neurochemical, Dopamine, may play a critical role. Dopamine is the primary neurochemical that regulates our pleasure sensation.

Eating temporarily boosts dopamine levels, but obesity may be associated with fewer Dopamine receptors which lead to less sensation of pleasure with eating. Research now suggests that the brain regions important to Dopamine expression when eating treats such as a milkshake does not get activated in those who are obese.

Interestingly, Dopamine has been studied as a primary mechanism for addiction and impulsive behavior including eating. Attempts are underway to try and understand how Dopamine might be triggered even in obesity to reduce impulsive eating so as to reduce gaining more weight. To read more about Dopamine, click here

Food and our Health

Friday, November 21st, 2008

With regard to the human brain we can provide general advice about how to promote brain health across the lifespan. When we were cavemen and cavewomen we ate one good fat for every bad fat. Today, we eat about 15 bad fats for every good fat. This is important because our brains are composed of about 60% fat and the lipid substance helps to facilitate information processing.

Thinking live a cave person might be a good exercise when thinking about what to eat. We should try and eat plants/vegetables, nuts, beans, fruit, fish, and lean game such as chicken. We should try to reduce processed foods, red meat, trans fatty acids, soda and foods high in sugar. We should strive to eat less than more and use utensils more often as it might help to less consumption of food and a healthier consumption of foods.

It is also important to realize that foods are supposed to be pleasurable and that an occasional piece of cake, pie, ice cream, etc will not cause major damage to the system. This is particularly true when one follows some of the general advice above.

I personally have begun a study of my own diet with increased intake of fruits and vegetables, reduction in processed fats, removal of soda from the diet, and increased fish and lean chicken. It is not uncommon for me to now have fruit in the am and day with a salad (olive oil and vinegar are good for the brain), and a piece of fish or chicken at night. I have been relatively consistent though I fail now and then. I am observing change in body mass and in psychology including energy and mental alertness.

Stay tuned and I will provide you an update in the near future!

Tea, Chocolate Chemical May Boost Memory

Tuesday, June 19th, 2007

We are starting off the Fit Brains Brain Health blog with some good news. Some food items that we actually do like might be good for us and not the reverse. In a recent study published in The Journal of Neuroscience, researchers believe it may be possible to boost memory. The article states:

“It may be possible to boost memory with a plant compound called epicatechin, which is found in foods and drinks including blueberries, grapes, tea, and cocoa”.
