There are many different factors that contribute to obesity an average figure from research studies estimates that obesity is about 40% genetic and 60% due to environmental factors, but there is a lot of variation in the scientific literature. Multiple factors acting upon a genetic background cause weight gain and obesity conditions associated with weight gain and biological changes in the body that occur as a result of weight gain contribute to progression of the disease, often trapping the individual in a vicious weight gain cycle.

  • Psychological “risk factors” of obesity the etiological basis of eating disorders and obesity usually lies in some combination of psychosocial, environmental, and genetic or biological attributes.

Genetic variations linked to obesity have been with us for millennia, but only in combination with the modern environment do they make us obese for example, fto (also known as “fatso”) is the gene with the strongest known effect on common types of obesity. Some genetic obesity syndromes are very severe, occur at a are likely to contribute to susceptibility to obesity in the genetic factors in human obesity. Two studies zero in on dna-based drivers of weight is obesity written in our genes in two separate papers, published in the journal science and in the journal of clinical investigation (jci), researchers describe new genetic factors that could explain weight gain in some people. Genetic obesity is a great mystery even though more than 15 billion people all over the world are overweight, and half a billion are obese, the world’s scientists can only theorise about how our genes have caused the recent explosion in obesity.
