1. Not getting a good night’s sleep.
Sleep deprivation can have a huge impact on your weight – to the point where if you’re chronically sleep deprived, you’ll notice yourself gaining weight, even if you’re conscientious about your diet. This is because the less you sleep, the higher your cortisol levels, which store fat – not to mention the less control you have over your appetite (1). If you have difficulty sleeping at night try drinking tart cherry juice and avoiding electronics before bed.
