Fast food does not fill you up: poor appetite regulation leads to obesity
Most people already know that regular consumption of fast food leads to obesity. Many studies show the negative effects of hamburgers, pizza and Co. on our health. But now the researchers have found another important reason why fast food can be harmful to our bodies. A team of scientists from the University of Macquarie in Australia found that eating junk food daily did not properly regulate appetite. The body does not send any signals that we are already full and it quickly comes to overeating.
Fast food suppresses neuronal appetite regulation
Our body has a protective mechanism that prevents us from overeating. After a meal, the appetite is suppressed by the hippocampus – a switching station in our brain. In this way, the brain regulates how many calories we eat every day. However, the research team from Australia found that unhealthy fast food such as french fries, pizza or hamburgers can prevent appetite control. The study examined 110 healthy subjects.
The participants were divided into two groups, the first group was made up of people who ate healthy food and the second – the test subjects who consumed junk food every day. The researchers found that the test participants' hippocampus in the test group did not function properly after just one week. As a result, they never got really full and consumed more and more junk food.
Fast food has a negative impact on our brain
In the end, people who eat fast food get caught in a vicious cycle. For one thing, they never get full and eat more and more, which can lead to obesity. On the other hand, the consumption of fast food leads to concentration problems and memory problems. Other studies show that fast food could even cause depression.
In the end, people who eat fast food are less productive at work and often do not feel comfortable in their own bodies. The good news is that if you completely change your diet and start eating healthy, you will quickly get back in shape. The hippocampus also begins to function properly.
