the team examines fat cells from very obese people who stomachs have been made smaller through barry actrix surgery. we all have tens of thousands of genes genes consist of a double helix of base pairs. there are 4 bases. they're known for short as a c t. a lot of our genes are the same in everybody. but sometimes variants emerge. it could be that even a tiny change has an impact on a person's weight. several genes are involved in obesity. best known perhaps of those involved in regulating leptin the hormone that makes you feel full. if there's some defect due to a wrong letter in the blueprint it leaves you feeling hungry all the time. which method for losing weight is best for any given person depends in part on his or her. genes doctors and geneticists are working together on this project. of our research is to improve our understanding of the causes of obesity and being overweight and ultimately to develop customized therapy for our patients. and. there is currently no gene therapy for treating obesity in humans. but researchers have developed a way to work out how susceptible a person
