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]
In medicine, genetic susceptibility to a disease refers to a genetic predisposition to a health problem, [1] which may eventually be triggered by particular environmental or lifestyle factors, such as tobacco smoking or diet. Genetic testing is able to identify individuals who are genetically predisposed to certain diseases.
Other transcription factors that have been known to respond to social factors include some factors broadly related to the neurobiology of threat including NF-κB (which, in addition to CREB, is a widely implicated transcription factor affecting pro-inflammatory gene expression), cyclic adenosine monophosphate , glucocorticoids (in particular ...
Scientists from the University of Exeter Medical School have found that people missing a specific blood group due to a genetic variant may be genetically predisposed to having obesity or overweight.
Experts have long known there is a genetic component to obesity, and a new study identified one particular gene that may be behind it. Researchers have found a ‘clear genetic trigger for obesity ...
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 ...
In the United States the number of children a person has had is related to their risk of obesity. A woman's risk of obesity increases by 7% per child, while a man's risk increases by 4% per child. [24] This could be partly explained by the fact that having dependent children decreases physical activity in Western parents. [25]
Some people’s genetics predispose them to obesity. But nature is not destiny. Here are five tips for losing weight.
