Ironically, sleep deprivation leads to weight gain. The reason? ‘During sleep, levels of ghrelin, the so-called hunger hormone, decrease, because we require less energy to sleep,’ says Natalie Pennicotte-Collier, sleep ‘super coach’ and therapist to elite athletes, including Team GB. ‘People who don’t sleep enough end up with too much ghrelin in their system.’ Disrupted nights also leads to a decrease in leptin, the hormone that tells the body when it’s full, Pennicotte-Collier adds. ‘Sleep-deprived bodies cry out for more food. If you have more than a year of five hours’ sleep or less a night, you could gain 10-15lbs.’ But our hormones themselves can be responsible for our poor sleep: if we’re stressed, with raised cortisol levels, our bodies find it impossible to switch off. And so the cycle continues. Pennicotte-Collier recommends sticking to the same bedtime and wake-up time, even on the weekends, to regulate your sleep and give your hormones a fighting chance.
