Scientists offer hope for genetically determined obesity
London, June 3: Unable to maintain weight loss due to your genetic predisposition to obesity? Take heart, an injectable drug widely used to lower blood sugar levels can help you fight overweight, suggest a study.
Around two to six per cent of all people with obesity develop obesity already in early childhood because they are genetically programmed to do so.
Obesity-causal mutations in one of their "appetite genes" gives them a strong genetic predisposition for developing obesity, also called monogenic obesity. Their experience of hunger is over-ruling and their feeling of satiety limited.
Researchers discovered that this group of people with obesity can lose weight with the help of the medicine liraglutide -- a modified form of the appetite-inhibiting hormone GLP-1 naturally secreted from the intestine when we eat.
"The appetite-inhibiting drug liraglutide has a positive effect on them. They feel less hungry and lose six per cent of their body weight within four months," said lead author Signe Sorensen Torekov, associate professor at the University of Copenhagen in Denmark.
In the study, published in the journal Cell Metabolism, the team have examined a small group with obesity caused by pathogenic mutations in the so-called MC4R gene and those with obesity without the mutations.
Both groups were treated with the medicine for four months; no changes were made to their diet and level of exercise in this period.
The individuals with this most common form of monogenic obesity lost 7 kg of their body weight compared to 6 kg for the people with common obesity.
Medicine acting as an analogue to our natural GLP-1 hormone is already available, as it has been approved by both the US Food Drug Association and European Medicines Agency for the treatment of obesity and Type 2 diabetes.
The study thus makes it possible to treat the most common form of genetically caused obesity, where patients respond poorly to existing treatments, the researchers noted.
As MC4R mutations cause obesity already in early childhood, the researchers hope the results can pave the way for new studies on young people in the future.

MP: 7-year-old girl raped and murdered; minor relative detained
Barwani (MP), Jan 28 (PTI) Police on Wednesday detained a 17-year-old relative of a seven-year-old girl in Barwani district of Madhya Pradesh for allegedly raping her and killing her by throwing her into a canal, a police official said.
Superintendent of Police Jagdish Dawar told reporters that the body of the child was recovered from the Indira Sagar Canal on January 26, following information from residents of a village in the Rajpur police station area of the district.
He said the post-mortem report concluded severe injuries to the girl’s private parts and attributed her death to drowning.
Dawar said a 17-year-old boy, a close relative of the girl, has been detained in connection with the rape-murder.
The teenager told the police that he kidnapped the girl from her home on the night of January 25 while her family members were asleep, took her to a nearby canal and raped her, according to the official.
When the girl started screaming during the sexual assault, the minor boy allegedly threw her into the canal, with the intention of killing her. The child drowned in the water body, the official said.
The detained minor will be produced in a juvenile court.
A case has been registered under the Protection of Children from Sexual Offences Act and the Bharatiya Nyaya Sanhita, and an investigation is underway, he added.
