We’ve known that obesity doesn’t have one cause. Instead, it’s a combination of factors over the long term, including exercise, nutrition, and genetics. People with gene combinations that put them at higher risk for obesity might be more likely to become obese by engaging in unhealthy behaviors than people without those genes. In a study published in the journal PLOS Genetics, researchers examined over 18,000 Chinese adults. They found that exercising for 30 minutes at least three times a week was associated with a lower incidence of obesity, even among people who are genetically predisposed to gain weight. Jogging was the form of exercise associated with the most benefit in terms of preventing obesity, but many types of exercise can lower your risk. Even just moving throughout the day might influence your gene expression and decrease your risk of obesity.
