Weight loss: Poor sleep and lack of exercise is a ‘double whammy’ when piling on pounds | Life | Life & Style

Sleep quality and low activity levels ramp up the risk factors for obesity, according to a large scale study of over 100,000 people. 

Scientists found that those who slept most restlessly had higher BMIs (Body Mass Index) than those who slept more efficiently. 

They now hope to create “personalised” health plans to combat obesity using peoples’ genetic risk factors for being overweight teamed with sleep data.

Professor Dr Timothy Frayling, of the University of Exeter Medical School, focused on data from 120,000 individuals aged 40 to 70.

They tested associations between genetics measures of activity and sleep.

Among participants with some genetic risk of obesity, those who woke up frequently or slept more restlessly had higher BMIs than those who slept more efficiently.
