Counterpoint to the previous news about mentally controlling our diet:
It sounds like science fiction, but a new paper in the journal BioEssays says that bacteria within us — which outnumber our own cells about 100-fold — may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity.

It may be possible to rewire your brain so that it wants — craves, even — healthier foods.
Previous studies have shown that high-calorie, fatty, sugary foods trigger the pleasure center of the brain. That’s why you naturally crave these unhealthy foods: You expect to be rewarded with dopamine for eating them.
But people in the experimental group showed a slightly different response to seeing high-calorie foods after participating in the intervention program. Researchers saw less activity in the stratum when participants were shown these foods and more activity when they were shown lower-calorie foods.
The sample size is incredibly small.
