Poor sleep habits increase weight gain for adults with genetic obesity risk quoting : Medical News Today

Poor sleep habits may lead to weight gain for adults with a high genetic obesity risk. Daytime napping and shift work were also linked to a heavier weight for those at high genetic risk for obesity. "It appears that people with high genetic risk for obesity need to take more care about lifestyle factors to maintain a healthy bodyweight. However, among people with a low genetic risk for obesity, abnormal sleep patterns did not appear have a significant impact on weight. Specifically, the researchers looked at participants' genetic risk for obesity, as well as self-reported data on average sleep duration, daytime napping, and whether their employment involved shift work.




"Our data suggest that sleep is another factor which needs to be considered, alongside diet and physical activity . "The study has been published in the American Journal of Clinical Nutrition (AJCN). "The influence of adverse sleep characteristics on bodyweight is much smaller in those with low genetic obesity risk - these people appear to be able to 'get away' with poorer sleep habits to some extent," he said.Co-author Dr Carlos Celis, who is a research associate of the Institute of Cardiovascular and Medical Sciences, added: "It appears that people with high genetic risk for obesity need to take more care about lifestyle factors to maintain a healthy body weight. Irregular sleeping habits could increase the risk of obesity and type 2 diabetes among those who are genetically overweight , according to new findings.The University of Glasgow study looked at how different sleep patterns can affect people and their health.They found that people with high genetic risk for obesity who slept for too short or too long a time, napped during the day, and worked shifts appeared to have a fairly substantial adverse influence on body weight In what the researchers say is the first study of its kind, the effects of these abnormal sleeping habits were observed alongside genetics of participants.People who are genetically prone to weight gain were shown to be roughly 4kg heavier if they slept for more than nine hours, while those who got less than seven hours of shut eye were 2kg heavier.Lead author Dr Jason Gill, from the Institute of Cardiovascular and Medical Sciences, explained that while the outcome was the same regardless of diet , health or socio-demographics, no link was found among those with a lower genetic risk of obesity.

Chronic stress may raise obesity risk

Chronic stress may raise the risk of obesity, research suggests. Based on their results, the researchers suggest long-term stress - as determined by cortisol levels in hair - may raise the risk of obesity. Hair cortisol levels used to assess stress-obesity linkFor their study, Dr. Jackson and colleagues sought to determine how chronic stress influenced the risk of obesity. "These results provide consistent evidence that chronic stress is associated with higher levels of obesity. New research strengthens the link between long-term stress and increased risk of obesity.
