In Rodents Fed High-Fat Diets, Gut Microbes Boost Hunger, Trigger Obesity

After several hints that gut microbes may be key players in the obesity epidemic, a new study provides a mechanistic explanation of how the intestinal inhabitants directly induce hunger, insulin resistance, and ultimately obesity in rodents.

The percentage of fat in our diets (since the early 80s) has gone down, but protein stayed the same, and carbs have gone up to pick up the slack.

Spinal Cord Injuries Lead to a Very Odd (But Serious) Risk

People who get serious spinal cord injuries have to adjust to a lot. That may be why, in the first year after their injuries, they are at serious risk for a potentially fatal condition called autonomic dysreflexia. Autonomic dysreflexia shows that the body can take itself down if its signals are ignored.

First signs are profuse sweating above your level of injury. Then chills with goose bumps, and very cold clammy skin. If its something like a clogged tube, that can be very dangerous. The bladder unable to empty itself makes the autonomic dysreflexic symptoms worsen.
