Question: How Obesity Gene May Be Driving Overeating?

Is overeating genetic?

Researchers have identified a gene (CYFIP2) associated with binge eating. This finding represents one of the first examples of a genome-wide significant genetic factor to be identified for binge eating in model organisms or humans.

How does overeating cause obesity?

When you eat, your body uses some of the calories you consume for energy. The rest are stored as fat. Consuming more calories than you burn may cause you to become overweight or obese. This increases your risk for cancer and other chronic health problems.

Is there a gene for obesity?

So far, rare variants in at least nine genes have been implicated in single- gene (monogenic) obesity. In most obese people, no single genetic cause can be identified. Since 2006, genome-wide association studies have found more than 50 genes associated with obesity, most with very small effects.

How do genes affect appetite?

As it turns out, genetics do seem to play a role. Perhaps surprisingly however, they have a larger influence on our appetite than our metabolism. People who gain weight faster seem to do so as they feel hungrier more often than those who are naturally thin.

What is the solution of obesity?

Preventing obesity in adults involves regular physical activity, a decrease in saturated fat intake, a decrease in sugar consumption, and an increase in fruit and vegetable consumption. In addition, family and healthcare professional involvement may help to maintain a healthy weight.

Can obesity be cured?

Experts: Obesity Is Biologically ‘Stamped In,’ Diet and Exercise Won’t Cure It. New research into the biological mechanisms of obesity suggests eating less and exercising more aren’t enough for people with long-term weight problems. The greatest threat to any species has always been starvation.

How is genetic obesity treated?

Gene therapy for obesity aims to increase or decrease gene product in favor of lipolysis and energy expenditure, leading toward fat reduction and loss of body weight. It involves successful delivery and expression of therapeutic genes in appropriate cells.

Can obesity run in the family?

Obesity can run in families — not because of genetics, but because of habits and environment, she says. More than a third of adults in the United States are obese, Moustaid-Moussa says.

How does the food we eat affect gene expression?

Tighter chromatin restricts the expression of genes. When we eat, tiny molecules that are broken down from food including carbohydrates, proteins, fats, and vitamins, are transported throughout the body to be used as energy or as building blocks.
