Can genetic obesity be cured?

Survey respondents felt farmers and grocery stores were relatively blameless for the rise in obesity.
Is obesity a disease or a choice?
Obesity is a chronic disease. According to the Centers for Disease Control and Prevention, obesity affects 42.8% of middle-age adults.

How does obesity affect the body?
Being obese can also increase your risk of developing many potentially serious health conditions, including: type 2 diabetes. high blood pressure. high cholesterol and atherosclerosis (where fatty deposits narrow your arteries), which can lead to coronary heart disease and stroke.
What are examples of nurture?
Nurture assumes that correlations between environmental factors and psychological outcomes are caused environmentally. For example, how much parents read with their children and how well children learn to read appear to be related. Other examples include environmental stress and its effect on depression.
Do genes play a role in obesity?
Science shows that genetics plays a role in obesity. Genes can directly cause obesity in specific disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome. However genes do not always predict future health. Genes and behavior may both be needed for a person to be overweight.
What genes are associated with obesity?
Table: Selected genes with variants that have been associated with obesity
|Gene symbol||Gene name|
|FTO||Fat mass- and obesity-associated gene|
|INSIG2||Insulin-induced gene 2|
