The science is solid and well explained. There are a few minor religious references.
NOTE - in the article there's some good news on reversing epigenetic changes - in emphasis.

Monkeys are born slackers - until someone turns off the 'reward' gene. Our current cultural predilection toward busyness may be a simple case of bad wiring
Monkeys are born slackers. The furry procrastinators of the natural world will happily wait for a banana to fall from the tree rather than exert any energy to climb up there and grab one.
Leisure-time exercise 'reduces depression risk'
The fact that people get more enjoyment from exercising during their leisure time is key
People who take regular exercise during their free time are less likely to have symptoms of depression and anxiety, a study of 40,000 Norwegians has found.
But physical activity which is part and parcel of the working day does not have the same effect, it suggests.
Writing in the British Journal of Psychiatry, the researchers said it was probably because there was not the same level of social interaction.
Interesting study. I wouldn't be surprised if similar findings occur when scanning the brains of heavy porn users. Note the silly revelation below:
"provides solid evidence that the problem can have a physical origin."
It's silly because there is no separation between brain structure and neurochemistry, and behavior or symptoms. When will they get it?

Altered brain blood flow may explain a lack of desire, scientists believe
Great article -I like all of Dr. Hymans articles (Huffington post).
My comments: One could substitute internet porn for highly palatable foods and get a similar article. Unfortunately, very little brain research has been done on Internet porn.

Tranquil living environments can positively affect the human brain function, according to researchers at the University of Sheffield.
The research, which was published in the journal NeuroImage, uses functional brain imaging to assess how the environment impacts upon our brain functions.
Sugars Power Over Humans Traced
Sugar may be a rich source of empty calories, but there's more to the story.

Sugar is the enemy, according to a growing body of research, and not just because it rots our teeth and adds padding to our thighs.
The real danger is fructose -- a main ingredient in table sugar, high fructose corn syrup, and fruit -- that actually gets into our cells and alters metabolism.
