The Claim
Genetically predicted higher levels of leisure screen time, including television watching and computer use, are associated with a 52% to 62% increased probability of obesity in individuals of European ancestry.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People with genetic patterns linked to more screen time have a 52% to 62% higher chance of developing obesity, regardless of physical activity or sleep duration.
See the scientific wording
Genetically predicted higher levels of leisure screen time, including television watching and computer use, are associated with a 52% to 62% increased probability of obesity in individuals of European ancestry, suggesting that lifelong predisposition to these sedentary behaviors contributes to obesity risk independently of physical activity or sleep duration.
People with certain genes that make them more likely to sit for long periods while using screens have changes in their fat tissue that cause it to produce more cortisol, reduce insulin control, and lower thyroid hormone levels. This combination slows down metabolism, makes the body store more fat, especially around the organs, and prevents fat from being burned for energy, leading to weight gain.
What the research says
1 studyPeople who are born with genes that make them more likely to watch TV or use computers for fun are also more likely to become obese — even if they exercise or sleep normally. The study proves this link using genetics, not just observation.
