Rats eating fat will gain weight like humans, but when they eat sugar they will not gain weight. Scientists will reveal the reason for us.Experimenting on some mice with different diets for each animal, scientists found that rodents gain weight rapidly when eating fat like humans, but the situation is similar. It does not happen when they eat a lot of sugar.
This study was done only in rats, but the relationship between it and human metabolism is still a problem. However, this raises the issue of how sugar affects human weight.
Carbohydrate is a health-damaging thing, or something that helps you to increase your energy, depending on the purpose we use. Likewise, fat not only makes us obese but also changes the appearance of thin people, depending on the purpose we use.
For a clear study of nutrients and metabolism in the human body, the simplest thing is to get someone just to be loaded into either fat, carbohydrate or protein for a long time. The reaction of the person's body over time is a clear result for the study.
But the ethical aspects will not allow us to do so. We can not force a person or group of people even if they are volunteers to eat such a limited menu during the long years. Therefore, these studies are still very few.
So a team of researchers from the University of Aberdeen and the Chinese Academy of Sciences have used animals, specifically rats, to replace humans in nutrition studies and exchanges. substance of the body.
Specifically, the team has developed 30 different diets that differ in fat, carbohydrate and protein levels and apply to nearly 1,000 mice. Each mouse in the test will eat the same regime for 3 consecutive months. Food is available as a buffet.
Using a camera, body mapping machine, scientists can closely control the body's response and change of the body after such a long period of limited eating. Finally, the team measured energy consumption and physical activity on the mouse group.
After analyzing and compiling the data, the researchers were amazed at the end result. The obese mice were the ones who ate a lot of fat.
"Not protein or carbohydrates, nor those that eat sugar with fat, nor gain weight as fast as those who eat only fat. Perhaps fat has stimulated the brain to make the body more appetite and eat more food, "said John Speakman of Aberdeen University.
While mice do not gain weight due to high sugar or protein intake, humans are the opposite, meaning that they are more likely to gain weight if they use too much sugar.
The researchers also identified the biochemistry behind the study. They found that signal changes in the brain involved eating pleasure, such as increased dopamine in the hypothalamus of the brain. It is the nutrients that affect the way we think in our eating, which affects our eating habits and behaviors.
In addition, to explain to mice eating a lot of protein but not gaining weight, the team said the body would continue to eat until enough amino acids that the body needs. Compared to people, low protein diets will cause us to eat more and hence lead to weight gain.
But the problem is, why do people use sugar to gain weight and mice do not? This is still being investigated by scientists, but they hypothesized that the energy needs of mice and humans are different, so that the brain reacts to nutrients that are specifically sugary different ways.
"This is just a study done on mice because they have many similarities in physiology and metabolism. The results of this study are not entirely the same if done in humans, but we will not do it in humans as it is very difficult to force a person to eat under such a regime for a long time, "said Speakman. .
Although this study can not be accurately applied to the human body, it is also a reminder to us about the relationship between diet and weight or health. Before using sugar or dough, consider carefully. The results are published in the journal Cell Metabolism
