Research Suggests Some Reasons Why People Overeat

One of the reasons why people gain weight is because they tend to overeat; however, what makes people overeat?

According to new researches, experts found out that obese people have a different response to food compared to people with normal weight. Obese people actually salivate more when they’ve tasted food, making them eat more.

Normally, the production of saliva decreases once a person got used to the taste of the food. There is a certain process called as habituation which is associated with feelings of fullness.

Studies suggest that the process of habituation is impaired in people who are obese; thus, they tend to eat more. Obese people are not very sensitive to feelings of fullness and as a result they overeat and gain more weight.

Since salivation is increased in obese people during eating, they tend to eat longer than normal. They do not immediately feel full and they eat more because they’re not yet satisfied, even if they’ve actually eaten a lot already.

However, these studies still lack answers as to when does impairment of habituation occur. Thus, more studies are still needed.
