Researchers have found a genetic connection between obesity in dogs and people in a recent study, shedding new light on the hereditary component of weight gain. According to the research recently published, genetic variants in people that predispose them to obesity are shared by dogs as well, cementing the link between obesity being a multifaceted, multifactorial condition.
Genetic Overlap Between Species.
Scientists compared genetic information from a large number of dogs and humans to find shared markers associated with obesity. The results point to the fact that genes that control body weight in humans also operate similarly in dogs. It is possible that the two species have similar underlying biological processes that lead to excess weight.
Dr. Emily Carter, one of the geneticists who worked on the study, said, “Our study indicates that genetic susceptibility to obesity is not unique to humans. Dogs, especially specific breeds, have similar hereditary components that predispose them to weight gain.”
Breed-Specific Risks in Dogs.
The research discovered that certain breeds of dogs, including Labradors and Beagles, are more prone to obesity at a genetic level because of differences in genes that control appetite and metabolism. These results are consistent with earlier research in humans, which has identified specific genetic markers associated with higher food consumption and reduced energy expenditure.
Dogs, similar to people, have an interaction of genetic and environmental components,” said Dr. Carter. “There’s definitely genetic propensity, but dietary and lifestyle habits continue to play important roles in obesity control for both groups.”
Implications for Obesity Management.
The identification of a genetic connection between dog and human obesity may open the door to more specific methods of weight control. Shared genetic causes could be used to develop new treatments for obesity that would benefit both human and veterinary medicine.
Experts cite that though genetics play a role in obesity, lifestyle factors are still the main factors in avoiding excessive weight. “Exercise and proper diet are crucial for dogs as well as people,” said Dr. Carter. “By treating obesity as a common health problem, we can create more effective prevention and treatment measures.”
A Step Forward in Obesity Research.
The researchers’ results suggest that further studies of genetic effects on obesity are vital. As they compare cross-species, researchers are in hope of learning new ways of managing the medical consequences of obesity.
With increased research, scientists might be able to use data derived from animals as valuable hints in developing therapy for humans struggling with obesity, making veterinary medicine more relevant and closing the gaps in medicine further.
