Why do people eat sugar and gain weight?

Fat-eating rats will gain weight like humans, but not eating sugar will not gain weight. Scientists will reveal the reason for us.

Performing experiments on several mice with different diets in each animal, the scientists realized that this rodent gained weight quickly when eating fat like humans, but the same situation was does not happen when they eat a lot of sugar.

This study is only done in rats, but its relationship with human metabolism is still another problem. However, this poses a problem with the influence of sugar on human weight.

Carbohydrates or things that damage health, or something that helps recharge energy, depending on the purpose we use. Likewise, fat not only makes us obese but also helps to change our appearance in lean people, depending on the purpose we use.

In order to study clearly the nutrients and metabolism in the human body, the simplest thing is to make someone only get fat or fat, or carbohydrates or proteins for a long time. The reaction of the body after a while is a clear result for the study.

But moral aspects will not allow us to do so. We cannot force a person or a group of people even if they are eating and drinking under such a limited menu throughout the long years. Therefore, these studies are still very few.

Therefore, a team of researchers from Aberdeen University and the Chinese University of Science used animals, specifically mice, to replace humans in the study of nutrients and exchange. substance of the body.

Specifically, the team built 30 different diets with differences in fat, carbohydrate and protein ratios and applied to nearly 1,000 mice. Each mouse in the test will eat in the same mode for 3 consecutive months. Food is available as we have a buffet.

Using cameras, body mapping machines, scientists can strictly control the body's response and body changes after such a long time of limited eating. Finally, the research team measured energy consumption and physical activity in mice.

After analyzing and synthesizing the data, the researchers were amazed at the final result. The obese mice are those who eat a lot of fat.

'Not proteins or carbohydrates, or those that eat sugar in combination with fat do not gain weight as quickly as those who eat fat only. Maybe fat stimulates the brain to make the body crave food and eat more food , "said John Speakman from Aberdeen University.

People are easy to gain weight if using too much sugar.

While mice do not gain weight by eating a lot of sugar or protein, humans are the opposite, meaning it is very risky to gain weight if using too much sugar.

The researchers also identified biochemistry after the study. They found that signal changes in the brain involve eating pleasure, such as increasing dopamine in the hypothalamus of the brain. It is the nutrients that affect the way of thinking in eating, thereby affecting our eating habits and behavior.

In addition, to explain to mice that eat a lot of protein but don't gain weight, the team says the body will continue to eat until it has enough amino acids that the body needs. Compared to people, a diet low in protein will make us eat more and thus lead to weight gain.

But the problem is, why do people use sugar, they gain weight and mice don't? This is still being explored by scientists, but they hypothesize that the energy needs of mice and humans are different , from which the brain reacts to nutrients that are specifically sugar-based. different ways.

'This is just a study done on mice because this animal has many similarities in physiology and metabolism with humans. The results of this study are not quite the same if done in humans, but we won't do it on people either because it's hard to force a person to eat in such a long time , ' Speakman said .

While this study is not applicable to the human body correctly, it is also a reminder to us about the relationship between diet and weight or health. Before using sugar or dirt, consider carefully. The results are published in the journal Cell Metabolism.
