Janey Lee Grace is a holistic living expert and author of bestselling books about the subject.
She explained why a lack of sleep can lead to weight gain: “Getting too little sleep can suppress hunger and make you insulin resistant. When cells become insulin resistant it means that your body tries to produce more, while there is already more sugar in the bloodstream.
“Of course, the excess insulin can lead to hunger pangs and the end result is that the body can store more calories as fat, so you are more likely to hang onto the fat,” Janey added.
“Without a decent amount of sleep your body makes less leptin and more ghrelin which increases appetite.”
