KOMPAS.com – Some people have to bother to adjust your diet and exercise regularly to get the desired body shape.
But there are types of people who are not fat or increase body weight, even though they don’t regulate eating patterns. Why so?
Professor of nutrition and food science from the University of Rhode Island, Kathleen Melanson, said that this condition is caused by many things.
“There are genetic, nutritional and behavioral factors. These three factors are relative to each individual, so the results are different, “Melanson said as quoted from Live Science, Sunday (2/8/2020).
One factor that has no relationship with body type, metabolism, or genetics is perception. Melanson says that someone who seems to eat a lot without gaining weight actually doesn’t eat more than you.
For example, someone who consumes ice cream every day might reduce the consumption of carbohydrates in other foods.
“Sometimes if you count their calorie intake, these people don’t eat more than you,” said Dr. Frank Greenway, Chief Medical Officer at Pennington Biomedical Research Center.
Physical activity is also a differentiator for these people. However, it is not limited to physical exercise or in the gym.
“Some people just move more, even though they are not athletes. For example they have a profession that requires active movement, or a housewife who has to look after children running all day, “said Melanson.
There is a study that says some people are born with the ability to burn calories faster. This was revealed by Dr. Ines Barroso, a researcher at the University of Cambridge who studies obesity from the genetic side.
One of the most important hormones that play a role in hunger is leptin. This hormone helps to determine how hungry we are for some time to come.
Apart from all that, genetic factors play a role in a person’s tendency to gain or lose weight. Researchers have identified more than 250 different DNAs related to obesity.
In the study, researchers compared 1,622 healthy people with a low BMI (Body Mass Index) against 1,985 people with severe obesity and 10,443 people with normal weight.
The study found that lean participants had fewer genes associated with obesity. However, genes alone do not determine your weight.
“We did not find genes that exclusively protect against obesity or make a person vulnerable to obesity,” Barroso said.
In the end, the answer is the tendency to gain or maintain weight is influenced by many factors that are within and beyond our control.
“However, someone who is gaining weight fast does not mean he lacks self-control. The assessment is not the same between one person and another person, “he explained.
