A Fitness Trainer Shares 9 Reasons You're Struggling to Lose Weight (and How to Fix It!)

Stress plays a big role in creating a leaner waist because it triggers the production of cortisol, which is a stress hormone that's linked to an increased appetite and more belly fat. Sleep and weight gain are also closely linked since a lack of sleep will raise cortisol levels, as well as grehlin (hunger hormone), and increase cravings, so you eat more. Find healthy ways to relax and bring more joy to your life each day, and aim to get seven to nine hours of sleep nightly.
