Obesity: The mutation of DNA is the reason why a diet high in carbohydrates causes obesity in some patients.

NEW YORK: Researchers have identified a common DNA mutation in animals that may explain why a high carbohydrate diet induces obesity and diabetes in some, but not others.

The study, published in the journal PLOS Genetics, highlighted a surprising difference between two groups of fruit flies when they fed on alternate diets rich in protein and carbohydrates .

Fruit fly larvae with a noted mutation in mitochondrial DNA (mtDNA) showed a marked increase in their development when consuming a diet rich in banana carbohydrates, but stagnated under a high-protein diet of pbadion fruit, reported the study cited by the agency.

Conversely, fruit fly larvae without this mutation thrived due to the high-protein diet, but lost frequency when administered as carbohydrates, the report says.

<p>  The six-year collaborative study conducted by Australian, American and Spanish researchers challenged the neutral theory of molecular evolution, that species changes at the molecular level are random, are not caused by selection and provide no advantage or disadvantage to the species.
</p>
<p>  According to lead author Bill Ballard of the University of New South Wales, research was a rare demonstration of positive selection at work in evolution.
</p>
<p>  Given that humans share 75% of the same genes as fruit flies and that they own the same mtDNA genes, it is likely, according to the study, that the same mutation inherited human mtDNA can metabolize carbohydrates in the same way.

<p>  "But the news is not all bad for people carrying the mutation," Ballard said.

<p>  "You need to manage your carbohydrate intake when you're younger, but if you're unlucky enough to develop Parkinson's disease, a high carbohydrate diet will help you maintain your weight," Ballard added.

In a world of convenience, where people prefer a bowl of instant noodles to a whole-grain chapatti, nutrition seems to have disappeared from our plates. And thanks to such practical options, the incidence of obesity has also exploded.

For all those who have surpbaded their healthy index and are overweight / obese, weight loss is becoming one of the main targets.

In this National Nutrition Week, we offer 5 diet plans that will help you lose weight in a healthy way.
