Here’s an interesting bit of biological research that suggests eating a high-fat diet may decrease your ability to exercise and lead to significant short-term memory loss. Not a good thing if you’re striving to be a world class joggler or even if you just want to 
lead a long healthy life.
The high fat research
In their study, researchers from the University of Cambridge in the UK gave rats a high-fat diet and examined the effects. After only 4 days of eating this diet (55% calories from fat) rats were less able to use oxygen to make energy needed for exercising. After 9 days, the rats took longer to go through a maze and they made more mistakes.
“A long weekend spent eating hotdogs, French fries, and pizza in Orlando might be a great treat for our taste buds, but they might send our muscles and brains out to lunch.” -Dr. Gerald Weissmann
I’m always a little skeptical of these kinds of studies since they aren’t usually done on humans and they try to simplify things a bit too much. How do they know it is only the fat that is responsible for the results? It’s possible that someone can eat a different high fat diet and come to different results. Also, has this been observed in humans?
I like the nutrition advice found in In Defense of Food
Eat food, not too much, mostly plants.
If you do this, the high fatness, laziness, and memory loss will take care of itself.
