Many people experience brief laziness after consuming a large meal of any sort. Researchers have concluded that the consumption of processed foods leads to lethargy and obesity.
UCLA has has released results to a study they performed involving rats and unprocessed and processed food.
Over a period of three months the Scientists noticed the rats that ate unprocessed food, such as ground corn, and fish meal maintained a healthy weight, and activity level.
The rats that were given a diet of lower-quality processed food containing more sugar, became obese.
After the initial test, the researchers put the obese rats on a healthy diet for nine days. The rats failed to make any improvements in their weight, or activity levels.
This has led the researchers to conclude that processed food contributes to major health risks, as well as cognitive impairments.
