In plain English

People with genetic traits linked to higher driving behavior have a 179% higher probability of developing obesity compared to those without these traits, based on studies of individuals of European ancestry.

See the scientific wording

Genetically predicted driving behavior is associated with a 179% increased probability of obesity in individuals of European ancestry, suggesting that lifelong predisposition to driving as a sedentary activity contributes to obesity risk more strongly than other sedentary behaviors studied.

Why this might work

People born with genes that make them more likely to spend long hours driving have fat tissue that produces more stress hormone and less effective insulin signals. This causes fat to build up around the organs, slows down calorie burning, and makes the body store more energy as fat, leading to obesity.

  1. Study: Sedentary behavior, physical activity, sleep duration and obesity risk: Mendelian randomization study

    People who are born with genes that make them more likely to drive instead of walk or bike have a much higher chance of becoming obese, and this study proves it using genetics — not just observation. Other sedentary habits like watching TV didn’t have as strong an effect.
