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]
The weight loss list is focused on the most effective eating plans for losing weight and sustaining weight loss, while the best overall diet prioritizes weight management and healthy eating. Here ...
There is a gradual weight regain after the first year of about 1 to 2 kg per year, but on the long-term this still results in weight loss. [4] Risk factors for cardiovascular disease and for diabetes are reduced for several years after taking part in a weight management programme, even if people regained weight. [45] [46]
Over 200 genes affect weight by determining activity level, food preferences, body type, and metabolism. [36] Having two copies of the allele called FTO increases the likelihood of both obesity and diabetes. [37] As such, obesity is a major feature of a number of rare genetic conditions that often present in childhood:
Still, despite the Task Force’s explicit recommendation of “intensive, multicomponent behavioral counseling” for higher-weight patients, the vast majority of insurance companies and state health care programs define this term to mean just a session or two—exactly the superficial approach that years of research says won’t work.
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 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.
Childhood obesity is defined as a body mass index (BMI) at or above the 96th percentile for children of the same age and sex. It can cause a variety of health problems, including high blood pressure, high cholesterol, heart disease, diabetes, breathing problems, sleeping problems, and joint problems later in life. [1]
