The extent of how your diet affects your body has been the subject of numerous studies throughout time. Now, there is a new study stating that eating a fatty, sugary diet can negatively affect your memory, attention, and mood in as little as four days.
According to the study published in the journal The Lancet, if you eat an unhealthy diet and avoid exercise, whether you have a small body frame or not, you are still at risk of diabetes, cancer, and cardiovascular diseases. In a study published in the journal Neurology and as stated above, memory, mood, and attention span can also be affected negatively in a much more acute measure of just four days.
Another study mirroring the same results was conducted by the University of Oxford showing that those eating a high-fat diet for five days experienced impaired attention span, memory function, and mood swings.
This study is supported by another research finding from Macquarie University in Sydney in which small framed participants who ate a sugary and fatty breakfast for four days showed similar cognitive problems as seen in people who are obese or overweight.
These studies show that, in a short span of time, the negative effects of a bad diet can set in causing the same damage as those seen in a poor long-term diet.
