Infection as a Cause of Obesity

Effects of Obesity on The Brain

This is one of the blogs I discovered while looking around the Web for

information on gaining and losing weight. I have to go to bed now, 

so I won't have another relapse of this cold, so I cannot write 

about this in detail.

The gist is that eating a fattening diet (that is to say, consistently 

consuming more calories than one burns) causes inflammation of 

brain tissue. One reason it's so hard to keep weight off after 

one has gained and lost may be damage to the portion of the

 brain that controls appetite.

There's also this on the AD36 virus, which appears to contribute to

 obesity in those infected:

Seven viruses have been reported to cause obesity in animal models by 

various research groups. 

We reported the first human virus, an adenovirus (Ad-36), which causes 

adiposity in chickens, rodents and non-human primates and shows 

association with human obesity. Our in-vivo  and in-vitro data show 

that Ad-36 increases adiposity, lowers serum lipids, increases insulin 

sensitivity and preadipocyte differentiation.
