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.
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 ...
Monogenic obesity is excess weight caused by a mutation in a single gene, as opposed to syndromic obesity not tied to a single gene variation and most obesity, which is caused by multiple genetic and environmental risk factors. Monogenetic obesity mostly affects the hypothalamus and leptin–melanocortin system (see hypothalamic obesity ...
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.
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 ...
Individuals who, due to genetic mutation, are unable to produce functional leptin or who produce leptin but are insensitive to it are prone to develop obesity. [4] This has been confirmed by experimental "knockdown" of leptin receptors in the lateral hypothalamus in rats, which caused the rats to consume more calories and increase in body ...
Some people’s genetics predispose them to obesity. But nature is not destiny. Here are five tips for losing weight.
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.
