Study says junk food can make you lazy
Here's another reason to break the habit of chowing down on junk food. According to a new study at UCLA, a diet heavy in processed food and sugar tends to make people overweight and lethargic. snacks.
The study was done in rats because they have physiological systems very similar to humans. The rats were placed in two groups and were fed then fed one of two diets for six months. The first group ate a normal rat’s diet of unprocessed foods, such as ground corn and fish meal. The second group was fed processed food with much more sugar.
After three months, the team noticed the rats eating junk food were obese, while the ones eating the unprocessed diet were not. They also found that when the rats were given an option to press a lever to receive a reward of food or water, the junk food diet rats took breaks twice as long as the healthy rats. This suggested that lethargy may actually be caused by junk food.
After six months, researchers switched the two groups’ diets for nine days. Despite the switch, the obese rats did not improve and the lean rats did not deteriorate, which suggests that it's a long-term pattern of eating junk food that causes obesity and cognitive impairments.
