The cause of obesity may be hidden in fructose – study
[ad_1]
Scientists believe that the real cause of obesity may be fructose.
This was reported by Medical Xpress with reference to a study published in the scientific journal Obesity.
Researchers from the University of Colorado suggest that when fructose is absorbed, it reduces the amount of energy in the body. It makes you feel hungry.
In their opinion, it is fructose that can unite other theories about the causes of obesity – the influence of fats, carbohydrates and sugar.

Fructose is a carbohydrate found in sweet fruits and honey.
Also, its content is high in sugar and corn syrup. In addition, fructose can be formed in the body from other carbohydrates, including glucose.
Co-author of the study, Richard Johnson, uses the term “fructose survival hypothesis”, which combines various assumptions about the cause of obesity, in particular the harmful role of fats and carbohydrates.
“Essentially, these theories, which place multiple metabolic and dietary factors at the heart of the obesity epidemic, are pieces of a puzzle united by one final piece: fructose.
Fructose is what causes our metabolism to go into low-energy mode and lose control over appetite, and fatty foods become the main source of calories that contribute to weight gain.” Johnson explains.
According to the scientist, this theory can be illustrated by animals that fall into hibernation. When energy levels drop, they start looking for food. For example, bears eat fruit to prepare for winter.
Fruit contains the most fructose, which can suppress active energy. Meanwhile, fat serves as its reserve.
However, foods with a high fructose content block the replacement of active energy from fat stores. They keep active energy at a low level – like a bear preparing for winter hibernation.
“This theory sees obesity as a low-energy state. The identification of fructose as a channel that redirects active energy exchange to fat storage shows that it is fructose that causes the energy imbalance that unites the theories,” – says Johnson.
This hypothesis can be the first step towards effective prevention of obesity. However, further research is needed to confirm it.
We will remind you that we previously wrote that scientists have discovered where the cause of Long COVID may be hiding.
