Like many other medical conditions, obesity is the result of an interplay between environmental and genetic factors. [2] [3] Studies have identified variants in several genes that may contribute to weight gain and body fat distribution; although, only in a few cases are genes the primary cause of obesity. [4] [5]
Using quantitative genetic analysis techniques, the researchers attempted to find either a causative or consequential relationship between the implicated genes and the obesity. They found that most of the interactions between the genes of interest and obesity were consequential—demonstrating that any alteration in gene activity is most likely ...
In this study, however, we found a clear genetic trigger for obesity,” said lead study author Dr. Mattia Frontini, British Heart Foundation senior fellow and an associate professor in cellular ...
Numerous studies aimed to provide insight into genetic, economic, and/or environmental causes of obesity. According to the "thrifty gene hypothesis, [18] a genetic theory explaining rising obesity rates, certain individuals are genetically predisposed to metabolize food more efficiently than others as a result of human evolution. In times of ...
Some people’s genetics predispose them to obesity. But nature is not destiny. Here are five tips for losing weight.
Prentice et al [5] predicted that the emerging molecular genetics field would ultimately provide a way to test between the adaptive 'thrifty gene' idea and the non-adaptive 'drifty gene' idea because it would be possible to find signatures of positive selection in the human genome, at genes that are linked to both obesity and type 2 diabetes ...
This heightened risk is primarily attributed to increased obesity and the displacement of physical activity,” said Hu. Even if you exercise regularly , sedentary behavior has serious health ...
The main problem with this idea is the timing at which the transition is presumed to have happened, and how this would then translate into the genetic predisposition to type 2 diabetes and obesity [citation needed]. For example, the decline in reproductive investment in human societies (the so-called r to K shift) has occurred far too recently ...
