Obese men put on a low-calorie liquid diet for seven weeks experienced substantial decreases in sleep apnea.
In a randomized controlled trial, obese men who spent seven weeks on a very low-calorie liquid diet saw their sleep apnea drop from severe or moderate to mild or normal, according to Kari Johansson, a PhD candidate at the Karolinska Institute in Stockholm, and colleagues.
At the same time, obese men in the control group — who maintained their normal diet — saw no change, Johansson and colleagues reported online in BMJ.
